Which equation does not have the same solution as the others?

x/4 = 2
x - 9 = 17
x + 12 = 20
2x = 16

Answers

X/4=2 is x=8
X-9=17 is x=26
X+12=20 is x=8
2x=16 is 8
So its the second one
The correct answer choice is B) x-9=17

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.

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

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.

Answers

Answer:

$58.80

Step-by-step explanation:

Area = Length * Width              square frame length & width will be the same

√196 = 14 inches                      

  196 = 14 * 14

   196 = 196

14 inches * 4 sides = 56 inches total needed for frame

Cost:

  56 inches * $1.05 = $58.80

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

X=5



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.
