Ответ:
B 4(2x-5) = 4
2x-5 = 1
2x = 6
x=3
Ответ:
56
Step-by-step explanation:
5x - 5 = 56 Set AC equal to EC since they are congruent
+ 5 + 5 Add 5 to both sides
5x = 61 Divide both sides by 5
x = 12.2
Plug this back into the original equation
5(12.2) - 5 = 56
61 - 5 = 56
56 = 56
The measure of AC is 56.
