Answer:

x = 8 (read below for Andre's mistakes)

Step-by-step explanation:

How to actually solve:

1/4(x+12) = 2

1/4(-4+12)=2

1/4(8)=2

How he solves:

1/4(x+12)=2

1/4(x+12)-12=2-12

1/4x=-10

x=-40

So apparently Andre's first mistake is he didn't use PEMDAS. His second mistake was instead of dividing by 4, he multiplied by 4.

The lines shown below are parallel. If the green line has a slope of -3/7, what is
BartSMP [9]

Answer: the slope of green line = -\frac37

Step-by-step explanation:

We know that,

If two lines are parallel then their slopes(rate of change of y with respect to x) are equal.

Given: The red line and the green line are parallel.

The slope of red line = -\frac37

Then, the slope of green line = -\frac37  [Slopes of two parallel lines are equal]

Hence, the slope of green line = -\frac37

95% of 160<br> I need help with this question
Pani-rosa [81]
You can write it several ways. Here are two:

1) Proportion
160/1.00=x/0.95
(160 is the whole, 1.00 or 100%, and x is 95% of the whole. Solve for x.)
x=<u>160*0.95<em /></u>  = 152/1 = 152<u>
</u>         1.00

2) Simple multiplication expression
"of" in math almost always means "multiply"
95% becomes 0.95. Multiply 0.95 by 160 to get your answer.
0.95*160=152

Either way, you get <u><em /></u><em />152, so that is your final answer.

The radius of Earth is 6,378.1 km, which is 63,532.9 km less than the radius of Jupiter. Find the radius of Jupiter
Vikentia [17]

All you need to do is add these two numbers together.

Radius of Jupiter = Radius of Earth + Difference between the two

Radius of Jupiter = 6378.1 + 63532.9

Radius of Jupiter = 69911 km
