A^4/b^5 then add two to each exponent
a^6/b^7

The negative exponents become positive when you switch them to the top or bottom.

Use the substitution method to solve the system of equations. Choose the

luda_lava [24]

Answer:

(2, 22 )

Step-by-step explanation:

Given the 2 equations

y = 7x + 8 → (1)

y = x + 20 → (2)

Substitute y = 7x + 8 into (2)

7x + 8 = x + 20 ( subtract x from both sides )

6x + 8 = 20 ( subtract 8 from both sides )

6x = 12 ( divide both sides by 6 )

x = 2

Substitute x = 2 in (2) for corresponding value of y

y = x + 20 = 2 + 20 = 22

Solution is (2, 22 )

What is the solution to this equation?

Darya [45]

Answer:

B) x=0

Step-by-step explanation:

x +20+ 10x= 9x +20

1st step: simplify the left side by combining like terms

10x+x=11x

2nd) 11x+ 20= 9x +20

Next, you subtract 11 and 9 which is equal to 2.

2x+20=20

Now, the 20 cancels out the other twenty so your left with 2x which is not an answer, therefore the only other number is 0 to be possible.

Check: 0+20+0=20 (first expression)

0x9=0 0+20= 20 (2nd expression)

20 = 20 so this is CORRECT!!!!!!!!

Find the GCF of 60, 96, and 156.

Temka [501]

Answer:

GCF = 12

for the values 60, 96, 156

Step-by-step explanation:

Solution by Factorization:

The factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60

The factors of 96 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96

The factors of 156 are: 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

Then the greatest common factor is 12.
