Angles 1 and 3 are supplementary
Answer:
x=5
Step-by-step explanation:
-2(-3+ x) = -4
Distribute
-2 * -3 + (-2) *x = -4
6 -2x = -4
Subtract 6 from each side
6 -2x-6 = -4-6
-2x = -10
Divide each side by -2
-2x/-2 = -10/-2
x = 5
3×2=6+4=d the 3×2 is how much the cost is and 6+4 is 10 so she paid 10 dollars
