c 12
b 11
d 13

c

Step-by-step explanation:

yup

the answer would be 11 weeks

Step-by-step explanation:

you take 45 then add 15 per week until you get to $210 which is 11 weeks

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
