The equation will be 2x + 7 = 3x

subtract 2x from bothsides, you get 7 = x

so x is equal to 7 

EDITED

sorry, i didnt read the sum part, so my answer is considered wrong ahaha

2(x+7) equals 3x

distribute, you get 2x+14=3x

then subtract 2x,

the answer for x is 14

X= in the number searched
2(x+7)= is the twice the sum of this number and seven.
3x= is three times the number

Because the twice the sum of a number and seven is three times the number, we suggest the following equation:

2(x+7)=3x
2x+14=3x
3x-2x=14
x=14

Answer: the number is 14.

(2b) A rectangular prism measures 2 & 2/5 inches by 3 & 1/5 inches by 2 inches. How many cubes with edge length 1/5 inch
erastova [34]

Answer:

1920 cubes.

Step-by-step explanation

Turn both the mix numbers into improper fractions.

2 2/5 = 12/5

3 1/5 = 16/5

Then you will turn 1/5 into its reciprocal and multiply both the improper fractions by it. You can just casually multiply 2 and 5.

12/5 * 5/1 = 12

16/5 * 5/1 = 16

2 * 5 = 10

Next you multiply all together to get 1920 cubes.

(I could be missing a step. I apologize if I did.)

Rewrite it in the form a^2 - b^2, where a = 2x and b = 5

(2x)^2 - 5^2

Use the Difference o Squares: a^2 - b^2 = (a + b)(a - b)

<u>(2x + 5)(2x - 5) </u>
