Solve this equation: –9h – 6 + 12h + 40 = 22.

Answers

Answer 1

Answer: Let's solve your equation step-by-step.−9h−6+12h+40=22Step 1: Simplify both sides of the equation.−9h−6+12h+40=22Simplify: (Show steps)3h+34=22Step 2: Subtract 34 from both sides.3h+34−34=22−343h=−12Step 3: Divide both sides by 3.3h3=−123h=−4Answer:h=−4

Answer 2

Answer: Combine like terms to get 3h + 34 = 22, subtract 34 from 22 to get 3h = -12, divide by 3 on both sides to get h= -4

Solve this proportion 10/8=n/10

Answers

The solution to the expression is n = 12.5.

We have,

To solve the expression 10/8 = n/10, we can use cross-multiplication.

Cross-multiplication involves multiplying the numerator of one fraction by the denominator of the other fraction.

10/8 = n/10

10 x 10 = 8 x n

100 = 8n

To solve for n, we divide both sides of the expression by 8:

100/8 = n

n = 12.5

Therefore,

The solution to the expression is n = 12.5.
