Answer:
x=5
Step-by-step explanation:
3x+2(-3x+11)=7
Use distributive property:
3x-6x+22=7
Combine like terms:
-3x+22=7
-3x=-15
Then divide:
-3x/3=-15/3 = 5
x=5
Answer:
x = 27
Step-by-step explanation:
39/26 = x /18
cross multiply
26x = (39)(18)
26x = 702
x = 27
It would be: 20* 10 = 200 ft²
so, the carpet should have the area of about 200 ft²
