Answer:
5x+ 4
Step-by-step explanation:
First, put all of the x variables together. So 3x+4x=7x
7x + 4 -2x Since the 2x is negative you can subtract it from 7x and get 5x.
you can not add the four to the 5x because it does not have a matching variable.
So, you have: 5x+ 4
The answer is choice D.
y = 2x
I will show two reasons why this equation is correct.
Let x = 1
y = 2(1)
y = 2
The first point in the table is (1,2).
In the table, x = 3 is the second choice.
y = 2(3)
y = 6
The second point in the table is (3,6).
Answer: y = 2x
Answer:
∠R = 55.6°
∠Q = 62.2°
∠S = 62.2°
Step-by-step explanation:
total interior angle sum = 180°
2x + 29 + 4x + 9 + 4x + 9 = 180
combine like terms:
10x + 47 = 180
subtract 47 from both sides of the equation:
10x = 133
divide both sides by 10:
x = 13.3
∠R = 2(13.3) + 29 = 55.6°
∠Q = 4(13.3) + 9 = 62.2°
∠S = ∠Q
Answer:
Z=0.75
Step-by-step explanation:
Given
Z is inversely proportional to X.
First we’ll define what an inverse proportion is. Inverse proportion is a relationship between two quantities such that if one quantity increases the other decreases.
Symbolically the relationship between Z and X can be defines as
Z ∝ 1/X
When the proportionality symbol is removed a constant is introduced.
Z= K/X
As we Know,
X=16
Z=1.125
We can find the value of K by using the values of Z and X
Putting in the values
1.125=K/16
K=1.125*16
K=18
Now, For
X=24
Z= 18/24
Z=0.75
