Answer:

-16.12

Step-by-step explanation:

Move the -3.1 to the other side so the variable s is isolated. Then on the right side, you will have -19.22 + 3.1. That equals <u>-16.12.</u> That is your answer.

Determine whether y varies directly with x. If so, find the constant of variation k and write the equation.
anyanavicka [17]
<span>The correct answer is that y does not vary directly with x.

Explanation<span>:
If y varies directly with x, this means that it would fit the equation y=kx for every point in the set.

For the first point, we would have 11=7k; this would mean that k=11//7.
For the second point, we would have 13=8k; this would mean that k=13/8.

Checking using proportions shows us that 11/7 does not equal 13/8:
cross multiply, and you have 11*8=7*13, or 88=91.

This is not true, so k is not a constant, and y does not vary directly with x.</span></span>

M&lt;KGH=x+161,m&lt;FGK=x+41,and m&lt;FGH=180° Find x
Butoxors [25]

Answer: x = -11   ∠FGK = 30°   ∠KGH = 150°

<u>Step-by-step explanation:</u>

∠FGK + ∠KGH = ∠FGH    <em>Segment Addition Postulate</em>

x + 41 + x + 161 = 180       <em>Substitution</em>

2x + 202 = 180  <em>               Simplify (added like terms)</em>

2x = -22                            <em>Subtraction Property of Equality</em>

x = -11                               <em>Division Property of Equality</em>

 

∠FGK = x + 41     = (-11) + 41    = 30

∠KGH = x + 161   = (-11) + 161   = 150

Solve the equation. (please *w*)<br> -4(2 - 1.2x) = 40
Ierofanga [76]

Solving for x would look like

rewrite: -4(2-1.2x)=40

distribute: -8+4.8x=40

add 8 to both sides of the equation: 4.8x=48

isolate x: x=10

So x = 10
