Answer:
B. 138.7
Step-by-step explanation:
Put the given number where the variable is and do the arithmetic.
h(x) = 5.7 -19x
h(-7) = 5.7 -19(-7) = 5.7 +133 = 138.7
Multiply 80 by 5/8ths.
80*5/8=50
Let's solve your equation step-by-step.
2b+1=16−3b
Step 1: Simplify both sides of the equation.
2b+1=16−3b
2b+1=16+−3b
2b+1=−3b+16
Step 2: Add 3b to both sides.
2b+1+3b=−3b+16+3b
5b+1=16
Step 3: Subtract 1 from both sides.
5b+1−1=16−1
5b=15
Step 4: Divide both sides by 5.
5b/5=15/5
<em>answer: b=3</em>
