Answer:

$\frac{10a+300}{200}$

Step-by-step explanation:

1. take 10 times a and get 10a and put in the numerator spot of your answer

2. then do 15 times 20 which is 300 so add 300 to 10a in the numerator spot of your answer

3. multiple 20 times 10 which is 200 and make it your denominator of your answer

This method is called the butterfly method

-7h+3(4-6h)=127 is h= 25?

GREYUIT [131]

Answer:

No, h = (-23)/5

Step-by-step explanation:

Solve for h:

3 (4 - 6 h) - 7 h = 127

3 (4 - 6 h) = 12 - 18 h:

12 - 18 h - 7 h = 127

-18 h - 7 h = -25 h:

-25 h + 12 = 127

Subtract 12 from both sides:

(12 - 12) - 25 h = 127 - 12

12 - 12 = 0:

-25 h = 127 - 12

127 - 12 = 115:

-25 h = 115

Divide both sides of -25 h = 115 by -25:

(-25 h)/(-25) = 115/(-25)

(-25)/(-25) = 1:

h = 115/(-25)

The gcd of 115 and -25 is 5, so 115/(-25) = (5×23)/(5 (-5)) = 5/5×23/(-5) = 23/(-5):

h = 23/(-5)

Multiply numerator and denominator of 23/(-5) by -1:

Answer: h = (-23)/5
