Answer:
a. x = 13/7
b. j = 3
c. y = 2
d. p = 25
Step-by-step explanation:
Here, it is convenient to combine like terms first. When you do that, you see that one side of the equation has a mix of a constant term and a variable term. Choose the term that matches the kind of term present on the other side of the equation (constant or variable), then add its opposite to both sides. Finally, divide by the coefficient of the variable.
__
a. 3x +13 = 10x . . . . combine like terms
13 = 7x . . . . . . . . . subtract 3x
13/7 = x . . . . . . . . divide by the coefficient of x

b. 10j -20 = 10 . . . . combine like terms

Comment on solving equations
In these "2-step" equations, the first step (after simplifying, combining like terms) is to "separate the variable and constant terms". The basic idea is to determine what term you don't want where it is, then add its opposite to both sides of the equation.
You can do anything you like to the equation, provided you do the same thing to both sides. When we say "subtract 3x," for example, we mean 3x is subtracted from both sides of the equation. This is an example of the use of the addition property of equality.
The same goes for multiplication or division. You can multiply or divide by anything you like, as long as you do the same thing to both sides of the equation. In the above, "divide by 7," for example, means both sides of the equation are divided by 7.
An employees new salary is $16,275 after getting a 5% rate. What was the salary before the increase in pay
Answer:
$15,000
Step-by-step explanation:
x + .05x = 16275
x(1+.05) = 16275
1.05x = 16275
x = $15,500

8ft,14ft,16ft what type of triangle do this numbers make
Answer: Scalene triangle
Step-by-step explanation:
A Scalene triangle is a type of triangle that all the three sides are not thesame. Here, the sides are 8ft, 14ft, 16ft. This shows that's it's neither and equilateral Triangle that has all sides equal or an isosceles triangle that has two sides equal. Also, it's not a right angle triangle.
Therefore it's an Scalene triangle
150-5r>87.5 Il mark brainliest
Answer:
r < 12.5
Step-by-step explanation:
Given
150 - 5r > 87.5 ( subtract 150 from both sides )
- 5r > - 62.5
Divide both sides by - 5, reversing the symbol as a result of dividing by a negative quantity.
r < 12.5
Answer:
r<12.5
Step-by-step explanation:
First, we need to isolate the variable so we subtract 150 from both sides.
-5r>-62.5
we then divide by -5 to get the value of x alone. Since this is an inequality and we are dividing by a negative we flip the inequality symbol. Remember to always flip the inequality symbol when dividing by a negative number.
R<12.5

Solve for x: 2x²+3x=2. Please use factoring. Thanks!
Answer:
x = [tex]\frac{1}{2}[/tex], x = - 2
Step-by-step explanation:
Given
2x² + 3x = 2 ( subtract 2 from both sides )
2x² + 3x - 2 = 0
Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 2 × - 2 = 4 and sum = + 3
The factors are + 4 and - 1
Use these factors to split the x- term
2x² + 4x - x - 2 = 0 ( factor the first/second and third/fourth terms )
2x(x + 2) - 1(x + 2) = 0 ← factor out (x + 2) from each term
(x + 2)(2x - 1) = 0
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
2x - 1 = 0 ⇒ 2x = 1 ⇒ x = [tex]\frac{1}{2}[/tex]

Is the equation x = 9 a linear equation? Does it describe a linear function? Explain.
No.
x = 9 isn't classified as a function at all. When you graph x instead of y. You will get a vertical line which isn't even a function.

Answers:
1: No, 10/12 Simplified is 5/6, and 15/30 simplified is 1/2
2: Yes, 1/5 / 3/5 Simplified is 1/3, and 1/4 / 3/4 simplified is 1/3
3: 60 words, You do 300 divided by 5, and you get 60 per minute
4: 240 words, You take the 60 per minute, and you multiply is by 4.
5: 24 doughnuts, 20x3 is 60 minutes. So, 12 doughnuts in one hour. Multiply is by 2, and you get 24 doughnuts per hour.
6: Walmart, To find out how much it costs, you so 1.25 / 5, and 0.80 / 2. So, Walmart is 0.25 per pack, and Ingles is 0.40 per pack. So, you can automatically tell that Walmart is cheaper, meaning the better buy.

which one
Answer:
7
Step-by-step explanation:
.........................
Greetings.
The answer is 7.
Explanation:
- What is Function? -Function is a set of relation with domains that are not repetitive. What I'm trying to say is that in a single set, there cannot be same domain values.
For example,
(1,2) (1,3)
The relation above is not a function since the domain is repetitive (There are two 1's as domain which is not a function.)
But If it is (1,2) (2,1) (3,1) Then It's a function. Because there are no repetitive domains.
The question asks you which value would give the whole set only a relation and not a function.
As explained, 2 repetitive, same domains don't make the relation a function, but rather a relation instead.
Hope this helps! :)
Feel free to ask anything in the comment/reply if you are curious/confused with Function.

write an equation of the line in slope-intercept form
(-5,-1) (3,-9)
Answer:
y = -x - 6
Step-by-step explanation:
y = mx + b
-1 = -5m + b --> b = 5m - 1
-9 = 3m + b --> b = -3m - 9
5m - 1 = -3m - 9
8m = -8
m = -1
Plug back in the first equation.
-1 = -5(-1) + b
-1 = 5 + b
b = -6

Match the given slope (m) and y.Intercept (b) with the equation of the line in slope intercept form
Slope, m. 2. y Intercept, b = 5
DRAG & DROP THE ANSWER
Slope, m = 3. y intercept, b - 7
OH
y = 122
Slope, m - 25. y-intercept, b = 0
O!
y = 252
Slope, m = 12. y Intercept, b=0
y = 10 + 15
Slope, m = 10. y-Intercept, b = 15
y = 2x + 5
y = 3x + 7
Answer:
is y=3x+7is the answer of this question
The slope intercept form of equation: y = mx + b
Therefore:
m = 2 and b = 5 ⇒ y = 2x + 5
m = 3 and b = 7 ⇒ y = 3x + 7
m = 3 and b = -7 ⇒ y = 3x - 7
m = 25 and b = 0 ⇒ y = 25x
m = -25 and b = 0 ⇒ y = -25x
m = 12 and b = 0 ⇒ y = 12x
m = 10 and b = 15 ⇒ y = 10x + 15
y = 122 ⇒ y = 0x + 122 ⇒ m = 0, b = 122
y = 252 ⇒ y = 0x + 252 ⇒ m = 0, b = 252
y = 10 + 15 ⇒ y = 0x + 25 ⇒ m = 0, b = 25
y = 2x + 5 ⇒ m = 2, b = 5
y = 3x + 7 ⇒ m = 3, b = 7

Answer:
x = 7
Step-by-step explanation:
All the angles in a triangle added together equals 180 so:
64 + 71 + 9x - 18 = 180
add like terms
9x + 135 - 18 = 180
9x + 117 = 180
subtract 117 from both sides
9x = 63
divide by 9
x = 7
Answer:
x=7
Step-by-step explanation:
A triangle equals 180 and 64+71 is 135. 180-135 is 45. 9x-18=45.
There are two vectors with magnitudes of 10 and 17 and an angle of28 degrees between them, What is the magnitude of the resulting vector?
Answer:
The magnitude of the resulting vector = 14
Step-by-step explanation:
Let say the magnitude of vector A = 10 and the magnitude of vector B = 17
The angle between them is 28°.
Then, that will form a triangle.
Let name the magnitude of the resulting vector to be C.
SO, by using Pythagoras rule:
hypotenuse² = opposite² + adjacent²
17² = 10² + C²
17² - 10² = C²
289 - 100 = C²
189 = C²
C = [tex]\sqrt{189}[/tex]
C = 13.75
C ≅ 14
Masada sold his radio to Agouti at sh 63,000 making a loss of 10%.
Agouti later sold the radio to Cheney at a profit of 15%.
(a) Calculate the amount of money Masada paid for the radio?
(03 marks)
Given:
Selling price of radio for Masada = 63,000
Loss = 10%
To find:
The amount of money Masada paid for the radio?
Solution:
Let x be the amount of money Masada paid for the radio.
According to the question,
[tex]x-10\%\text{ of }x=63000[/tex]
[tex]x-\dfrac{10}{100}x=63000[/tex]
[tex]x-0.1x=63000[/tex]
[tex]0.9x=63000[/tex]
Divide both sides by 0.9.
[tex]x=\dfrac{63000}{0.9}[/tex]
[tex]x=70000[/tex]
Therefore, Masada paid 70,000 for the radio.
