Answer:
Start by subtracting 3t from both sides of your equation
13t+4=12+3t
-3t. -3t
that gives you
10t+4=12
Subtract 4 from both sides
10t+4=12
-4. -4
That gives you
10t=8
Divide both sides by 10 to leave the variable by itself
10t=8
÷10. ÷10
That leaves you with
t=8/10 or t= 4/5 if you simplify.

Answer:
36
Step-by-step explanation:
12 x 3 = 36
The first equation uses the first and second coupons. the coupon (1-y)40 will take y% off of the dress pants so the answer is 40(1-y)
Y=mx+b, m=delta y / delta x...from the table we can see that m=3/2 so our equation becomes:
y=3x/2 + b, using any point, I'll use (2,2) we can now solve for b, or the y-intercept...
2=3(2)/2 +b
2=3+b, b=-1 our line is thus:
y=1.5x-1
