Order of Operations

Rufina [12.5K]

9 - (a - 7)

Note that - = -1

First, distribute - 1 to all terms within the parenthesis

-1(a - 7) = -a + 7

9 - a + 7

Combine like terms

9 + 7 = 16

-a + 16, or A. 16 - a is your answer

hope this helps

When estimating a square root, how do you find the numerator in your fraction of your estimation?

Tasya [4]

Answer:

To get your numerator you subtract the first two numbers, 63 - 49 = 14. That leaves you with 14 over 15 or . 93. Since the square root of 63 is higher than 7 but less than 8 your whole number is 7

Y=-6x + 5<br> x - y = 5

rodikova [14]

Answer:

y = $\frac{-25}{7}$ or -3.571

x = $\frac{10}{7}$ or 1.429

Step-by-step explanation:

x - y = 5

x = 5 + y

Solve for y:

y = -6x + 5

y = -6(5 + y) + 5 Substitute x with 5 + y

y = -6(5) - 6y + 5

y = -30 - 6y + 5

y + 6y = -30 + 5

7y = -25

y = $\frac{-25}{7}$ or -3.571

Solve for x:

x = 5 + y

x = 5 + -25/7

x = $\frac{10}{7}$ or 1.429
