Which one is it A. B. C. or D.

nadya68 [22]

7x + 2y = 2
2x - y = 10

2y = - 7x + 2
- y = - 2x + 10

2y = -7x + 2
y = 2x - 10

$y=\frac{-7x+2}{2}$
y= 2x - 10

y = -3.5x + 1
y = 2x - 10

Now, let's find "x" first by doing a substituion !

2x - 10 = - 3.5x + 1
y = 2x - 10

2x + 3.5x = 1 + 10
y = 2x - 10

5.5x = 11
y= 2x - 10

$x = \frac{11}{5.5}=2$
y= 2*2 - 10 = 4 - 10 = -6

In short, the answer would be : y = -6 (Option B).

Hope this helps !

Change the fraction 3/4 to a percent

Rom4ik [11]

To convert 3/4 to a percent we need to convert 3/4 to a decimal and then multiply the decimal by 100. Lets do it:-

To convert a fraction to a decimal we have to divide the numerator by the denominator.

3/4
3 ÷ 4 = 0.75

Decimal = 0.75

0.75 × 100 = 75
75%.

So, 3/4 in percent form is 75%.

How do I solve/simplify??

Mekhanik [1.2K]

(3s^13)(9s^-5) is simply a matter of multiplication.

First, multiply the coefficients, or the numbers in front of the s. In this case, 3s x 9s = 27s.
When multiplying exponents, you simply add them, so the next step is 13-5 or 8. Therefore your answer is 27s^8
