Answer:
D. 3x + 1 < x + 3
Step-by-step explanation:
Assuming the number to be x
Three times a number = 3x
1 more than 3 times a number = 1 + 3x
The symbol for less than is = <
The sum of 3 and the same number = x + 3
After assembling the given data, the equation will be:
3x + 1 < x + 3
[The options given in the question are incorrect. The correct options will be:
A. 3x + 1 = x + 3
B. 3x − 1 = x + 3
C. 3x − 1 > x + 3
D. 3x + 1 < x + 3 ]
∴ Option D is the correct answer.
Paul developed a roll of film containing 36 pictures. If he made 2 prints each of half of the pictures and 1 print of each of the rest, how many prints did he make in all?
Answer:
54
Step-by-step explanation:
Total pictures in the roll = 36
half of the roll = 1/2 of the total pictures in the roll = 1/2 * 36 = 18
Given Paul made 2 prints of each of the half pictures
no. of prints made of half of the pictures = 18*2 = 36
No. of prints left after the half of the roll is printed for two prints= 36-18 = 18
No. of prints made of rest of the pictures 1
Therefore , no of prints made of rest half of pictures = 18*1 = 18
Total prints made = 36 + 18 = 54.
Thus, Paul made 54 prints in all.

Pls mark my ans as brainliest :)Consider the line - 8x-5y = -7.
What is the slope of a line perpendicular to this line?
What is the slope of a line parallel to this line?
Answer:
See below
Step-by-step explanation:
First, you need to find the slope of the given line. You can do this by rearranging the equation so that it is in slope-intercept form (y = mx + b).
-8x - 5y = -7
-5y = 8x - 7
y = -8/5x + 7/5
The slope of this line is -8/5.
The slope of a line that is perpendicular will be the negative reciprocal. You have to change the sign, and basically flip the numerator upside down. The slope of the perpendicular line will be 5/8
-8/5 = 8/5 = 5/8
The slope of a line that is parallel will be equal. This means that the slope will be -8/5.

A sunflower grows 8 feet in 92 days. Assuming that it grows at a constant
rate, explain how you could use this information to find the number of
days it took for the sunflower to grow 6 feet. Use vocabulary words in your
explanation.
Answer:
69 days
Step-by-step explanation:
Given that sunflower grows at constant rate.
Let the rate of growth be x feet per day. It means sum flower grows x feet every day.
in 1 day plant grows x feet,
so in 92 days plant will grow 92*x feet
In 92 days the growth of plant will be = rate of growth *92 = 92*x = 92x feet
But given that A sunflower grows 8 feet in 92 days
so, 92x will be same as 8 feet.
lets put it in equation
92x =8 feet
x = 8/92 = 2/23
Thus, rate of growth of sunflower plant is 2/23 feet per days.
it means it grows 2/23 feet every day.
Let number of days taken to grow 6 feet be y days
in 1 day plant grows 2/23 feet feet,
so in y days plant will grow 2/23*y feet
In y days the growth of plant will be = rate of growth *y= (2/23)*y = 2y/23 feet
But 2y/23 should be equal to 6 feet
2y/23 = 6
Multiplying both side by 23
2y/23 * = 6 *23
=> 2y =138
dividing both side by 2
2y/2 =138/2
=> y = 69
Thus, it will take 69 days for sunflower to grow 6 feet.

2 Two cars leave the park at the same time. One travels north at a speed of 50 km/h for 2 hours. The
second car travels west at a speed of 80 km/h for 2 hours. After the 2 hours, how far apart are the two
cars? Be sure to draw a diagram illustrating this situation
3 Asmall tree is beginning to lean The owner decides to set up a tension wire to straighten the tree's
growth The owner chooses a wire which is 5 m in length to straighten the tree. The tree is 4 m high
How far must the owner secure the bottom of the wire from the base of the tree (assuming he attaches
the tension wire to the top of the tree)?
Answer:
1) 244.92cm 2) 188.68 km 3) 3m
Step-by-step explanation:
1) We are finding the circumference of the basketball in this situation. C=pi(d), d=diameter, C=circumference. So, C= 3.14(78), and finally C= 244.92 cm.
2) We can begin to approach this problem by finding how far each car has traveled over 2 hours. The car heading north is going 50 km/h, so for two hours it has covered 100 kilometers. The car going west is at 80 km/h, so for two hours it has covered 160 kilometers. Now, we could draw this as a right triangle, with one leg being the north-headed car 100 km away from the start, and the other leg being the west moving car 160 km away from the start. The hypotenuse represents the distance between them. Now we use the pythagorean theorem! north car is a, west car is b. a^2+b^2=c^2. 100^2+160^2=c^2. 35600=c^2. take the square root of both sides for c=188.68. The distance between the two cars is approx 188.68 km.
3) `This situation can be represented as a right triangle. The height of the tree, 4m, is the height of the triangle, and the wire, 5m, is the hypotenuse. We are trying to find one of the legs, which represents the ground to the base of the tree. In the pythagorean theorem, we have a^2 and c^2, and just need to find b^2. Let's plug it into the equation:
4^2+b^2=5^2
16+b^2= 25
b^2=9
b=3

simplify this algebraic expression completely.
Answer:
Option 4
Step-by-step explanation:
=> 8y-2(y+4)
=> 8y-2y-8
=> 6y-8
Answer:
The last option, D.
Step-by-step explanation:
Alright, so we are given this expression that is not simplified. First, we need to apply the distributive property. Since it is -2(y+4) or -2 times y plus 4.
We need to multiply -2 by each term inside the parentheses.
-2 times y is -2y and -2 times 4 is -8.
Remember, a positive times a negative is always negative.
Now we have 8y-2y-8.
We can simplify this even more by combining like terms.
8y and 2y are like terms because they have the same variable stuck to it. 8y-2y is 6y.
We can't combine like terms with -8 because -8 doesn't even have a variable. It is not coefficient, it is just a constant.
Therefore, the simplified algebraic expression is 6y-8.
Hope this helps!

x + y + z = 40
2x + 3y + 3z = 110
x + y + 2z = 50
Step-by-step explanation:
let
x = photograph
y = painting
z = neckless
the first part reads that jada sells 1 photograph, 1 painting, and 1 neckless. this written in a mathematical formula will be x + y + z = 40
the second part reads that jada sold 2 photographs, 3 paintings, 3 necklaces. This written as a mathematical formula will be 2x + 3y + 3z = 110
the third part reads that jada sold 1 photograph, 1 painting, and 2 necklaces. this written in a mathematical formulawill be x + y + 2z = 50

Step-by-step explanation:
For her birthday, Samantha received a gift card, with a value of $200, to a department store. She wants to purchase at least 5 articles of clothing for work. At the store, sweaters cost $24.49 each and dress pants cost $36.99 each. If Samantha does not spend more than the amount on the gift card, which system of inequalities could be used to determine the number of sweaters, s, and the number of dress pants, p, she can buy? A. s + p $200 B. s + p > 5 $24.49s + $36.99p 5 $36.99s + $24.49p < $200
Your answer choices are a bit jumbled and some symbols are missing. However, the answer will involve the two inequalities
[tex]s+p \ge 5 \ \text{ and } \ 24.49s+36.99p \le 200[/tex]
The first inequality is the idea where she wants to buy at least 5 articles of clothing. The expression s+p is the total amount of sweaters and pants purchased, and we want this quantity to be 5 or larger.
The second inequality has the total amount spent (24.49s+36.99p) to be at most 200 dollars. In other words, we want the amount spent to be $200 or less.
24.49s = amount spent on just the sweaters
36.99p = amount spent on just the pants
24.49s+36.99p = total amount spent

Find the perimeter of the right triangle. If necessary, round to the nearest tenth.
A right triangle with side 13 inches, side 14 inches, and blank hypotenuse.
a.
91 in.
b.
46.1 in.
c.
19.1 in.
d.
182 in
Answer:19.1
Step-by-step explanation:
Answer:
B. 46.1 in
Step-by-step explanation:
First, we must find the hypotenuse of the triangle.
Since this is a right triangle, we can use Pythagorean Theorem.
a^2+b^2=c^2
where a and b are the legs and c is the hypotenuse.
13 and 14 are the legs, because they form the right angle. x is the hypotenuse because it is opposite the right angle.
13^2+14^2=x^2
Evaluate each exponent.
13^2=13*13=169
14^2=14*14=196
169+196=x^2
Add 169 and 96
365=x^2
Take the square root of both sides.
√365=√x^2
√365=x
19.1049732=x
Round to the nearest tenth.
19.1=x
The hypotenuse is 19.1 inches
Now, find the perimeter. Add up all the sides of the triangle: the legs (13 in and 14 in) and the hypotenuse (19.1 in)
13 in +14 in +19.1 in
46.1 in
The perimeter is 46.1 inches and B is correct.
