Solve the equation: -18 = 6(2 + x)
Answers
Answer:
-30
Step-by-step explanation:
Multiply 6 and 2 to get 12
Then subtract -18 and 12 to get -30 and
-30 divided by x or 1 is -30
Answer:
x = -5
Step-by-step explanation:
first, you distribute the 6, which gives you -18=12+6x. then you subtract the 12 on both sides giving you -30=6x. Finally you divide the 6 from the x and the -30 which leaves you with -5 = x
The diameter of a circle is 19 cm. Find its circumference in terms of pi.
Answers
Answer:
3.14x19
Step-by-step explanation:
59.66 is the circumference
The circumference in terms of pi is 18π cm.
Give that the diameter of the circle=19 cm. Then radius=9.5 cm.
What is the formula to find the circumference of the circle?In geometry, the circumference is the perimeter of a circle or ellipse. That is, the circumference would be the arc length of the circle as if it were opened up and straightened out to a line segment. More generally, the perimeter is the curve length around any closed figure.
The formula to find the circumference of the circle is 2πr.
Now, circumference=2π×9.5 cm=18π cm
Therefore, the circumference of a circle is 18π cm.

Solve for x and/or y:
Answers
Answer:
C) x=35
Step-by-step explanation:
First, we know that the total amount of degrees in a rotation is 360. As the picture tells us, the opposite angles will be exactly the same. Taking this information, we can have the following equation:
4x + 2(3x+5) = 360
By now using our linear equation skills, we get:
10x+10=360
10x=350
x=35
The degree amount of x for c) is 35 degrees.
C. Since the angles form a linear pair, their sum equals 180.
So, 2x + 3x + 5 = 180
x=35
D. Since the angles are verticle, they equal each other.
So, 3x + 5 = 5x -57
x=31

Workers install 720 chairs at a constant rate. After 4 days, the workers still have to install 480 chairs. How much time does it take to install the chairs from start to finish?
Answers
Answer:
12 days
Step-by-step explanation:
As, After 4 days, remaining chairs = 480
So, the number of chairs already installed = 720-480 = 240
In 4 days they constructed = 240
In 1 day =240/4 = 60
So in 1 day = 60
So in "x" day = 720
So = 720/60
= 12
= 12 days

5) A theater earns $3640 from a concert. An orchestra ticker costs three times as
much as a balcony ticket. Write a system of linear equations that represents this
situation. What is the price of each ticket?
Ticket Type
orchestra
balcony
Number Sold
148
76
Answers
Answer:
148x+76y=3640
The orchestra tickets costed $21, the balcony tickets costed $7
Step-by-step explanation:
You do 148x because we know that they sold 148 tickets we just need to know the cost and 76 because we know that have sold 76 balcony tickets.
I’m don’t really know how to say the rest
The price of each ticket will be;
The price of balcony ticket = $910
So, The price of orchestra ticket = $2730
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
A theater earns $3640 from a concert.
And, An orchestra ticket costs three times as much as a balcony ticket.
Now,
Since, An orchestra ticket costs three times as much as a balcony ticket.
Let price of balcony ticket = x
So, The price of orchestra ticket = 3x
Hence, We can formulate;
⇒ x + 3x = $3640
⇒ 4x = $3640
⇒ x = $3640/4
⇒ x = $910
Thus, The price of balcony ticket = x
= $910
So, The price of orchestra ticket = 3x
= 3 × $910
= $2730
Thus, The price of each ticket will be;
The price of balcony ticket = $910
So, The price of orchestra ticket = $2730

In parallelogram HIJK, the measurement of angle H is 45 degrees, find the measure of angle K
Answers
Answer:
< K = 135
Step-by-step explanation:
< K = 180 - < H
= 180 - 45 = 135
The measure of angle K is 135 degrees and this can be determined by using the properties of a parallelogram.
Given :
In parallelogram HIJK, the measurement of angle H is 45 degrees.
The following steps can be used in order to determine the measure of angle K:
Step 1 - According to the definition of a parallelogram, the opposite sides of a parallelogram are parallel.
Step 2 - According to the given data, the measurement of angle H is 45 degrees.
Step 3 - So, according to the definition of a parallelogram, the measure of angle K is:

A restaurant sells 10 tacos for $8.49, or 6 of the same kind of taco for $5.40. Which is the better deal? NEED THIS ASAP
Answers
Answer:
849
Step-by-step explanation:
To get the better deal, you should find the selling prices for a single tacos in both cases and compare the amounts.
In the first one, 10 tacos for $8.49
This means 1 tacos sells for $8.49/10 = $0.849
In the second one, 6 for $5.40, this means for a single tacos, the selling price is $5.40/6 =$0.9
The better deal is the first one that sells one taco for $0.849 compared to the second one that sells one tacos for $0.9
Answer:
The better deal is the 6 tacos for $5.40
Step-by-step explanation:
10/8.49= $1.18
6/5.40=$1.1
The 6 tacos are about $1.11 per taco and the the 100 tacos are $1.18 per taco

4. 3/4 bucket per hour
Answers
Answer:
4. 3/4 bucket per hour
Step-by-step explanation:
The bucket was 3/10 full after 2/5 of an hour.
How much water is leaking per hour.
Quantity of water leaking per hour = 3/10 ÷ 2/5
= 3/10 × 5/2
= 15/20
= 3/4
Quantity of water leaking per hour = 3/4 bucket per hour
The answer is
4. 3/4 bucket per hour
