Solve for x:
(-3/2)x - 9 = -27
Select one:
a. −24
b. −12
c. 11
d. 12
Answers
This is what the equation looks like: [tex]\frac{-3}{2}x - 9 = -27[/tex]
First, we transpose the terms to the other side. So after transposing [tex]-9[/tex], you get: [tex]\frac{-3}{2}x = -27 + 9[/tex]
Add them and you get: [tex]\frac{-3}{2}x = -18[/tex]
Next we transpose the coefficient of [tex]x[/tex] which is [tex]\frac{-3}{2}[/tex] to the other side, and while doing so the operation changes to a division. When dividing rational numbers, you take the reciprocal so you get: [tex]x = -18 * \frac{-2}{3}[/tex]
Multiply them and you get: [tex]x = 12[/tex]
Therefore, Option D is the correct answer :D
The perimeter of the original rectangle on the left is 30 meters. The perimeter of the reduced rectangle on the right is 24 meters. What is x, the width of the original rectangle on the left? Round to the nearest hundredth if necessary.
A) 5 meters
B) 8 meters
C) 10 meters
D) 12 meters
Answers
Explanation:
If the triangle on the rights perimeter is 24 and two of the lengths are 8 then we know 8+8=16 24-16=8 8/2=4
So the triangle on the right has the numbers 8 and 4 as it’s length and width
So then you would find out how much it was dilated to get from 30 to 24
30/24 and you get 1.25 so you multiply 4 by 1.25 and get 5, and then to double check you can multiply 8 by 1.25 and get 10 then add it all together
5+5+10+10=30 so you know that’s correct.

A rectangular poster has an area of 504 square centimeters. The width of the poster is 14 centimeters. How long is the poster?
Answers
Answer:
36 sq. cm.
Step-by-step explanation:
We find area by multiplying the length by the width of the poster. But now, in your question we want to find the length of the poster. We are given the area, 504 square centimeters, and the width, 14 centimeters. Since multiplication and division are inverse operations, we will do the opposite of multiplication, division, to find the quotient, the length of the poster. 504 divided by 14 can be written like this: 504 / 14. 504 / 14 = 36 sq. cm. We can check our answer by multiplying 36 and 14 to get 504. So, we know our answer is correct.

Mei has 60 milliliters of a solution that is 35% nitric acid. How many milliliters of nitric acid does the solution contain?
(answer this and show your work please)
The solution contains _answer here_ milliliters of nitric acid.
Answers
Answer:
21ml
Step-by-step explanation:
60ml. 35% acid. What is 35% of 60 ml?
÷10 to find 10%
60÷10=6
6=10%
But this is no use
because you cannot multiply 10%to get 35%
(35% is not a multiple of 10)
So we try...
10%÷2=5%
So ÷2 to find 5%
6÷2=3
So 3=5%
5%x7=35%
So, we do
3x7=21
So 35%=21
Answer:
21ml

Which equation does not have the same solution as the others?
x/4 = 2
x - 9 = 17
x + 12 = 20
2x = 16
Answers
X-9=17 is x=26
X+12=20 is x=8
2x=16 is 8
So its the second one
8/4=2
8-9=-1
8+12=20
2(8)=16
The second one isn’t correct because 8-9 is not 17, it is -1.
