Answer:

Step-by-step explanation:

Exponent properties state that when two like bases are being divided, the exponents can be subtracted. So the first step in simplifying is to subtract the two exponents, 4-2=2. This leaves the fraction as $\frac{7^{2} }{7^{0} }$ , since anything to the power of 0 is just 1, the simplified expression is $7^{2}$ . Then, because they are both constants, 7 can just be squared. This equals 49.

Solve for x 6x + 3 - 1/2 x = -2x +5

UkoKoshka [18]

First, group the x values together (on one side) and the other values on the other.

6x + 3 - 1/2 x = -2x +5
6x - 1/2 x + 2x = 5 - 3

Now solve!

7 and 1/2 x = 2
x = 8

BARSIC [14]

Mr. Zelman gave 400 books to his nephew

Solution:

Given that, Mr. Zelman wants to give 50% of his comic book collection to his nephew Alex

Mr. Zelman has 800 comic books

Number of books with Zelman = 800

Mr. Zelman wants to give 50% of books to Alex

Number of books given to nephew = 50 % of books of Zelman

Therefore, we have to find 50 % of 800
