Find the percent of the number. 50% of 70 is
.

Question 2
Explain your method.

35

Step-by-step explanation:

Using proportions, you are correct:

70/x = 100/50

cross multiply

100x = 3500

divide both sides by 100 to get your answer.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
