Answer: -13k+11
Step-by-step explanation:
Combine like terms
-15k+2k=-13k
-1+12=11
65 + (3x-10) + 2x = 180
65 +5x-10 = 180
55 + 5x =180
5x = 125
x = 125/5 = 25
x = 25
B = 3(25)-10 = 75-10 = 65
C = 2(25) = 50
Answer:
11 if you mean x^2
Step-by-step explanation:
Since we are solving for x, we need to just get x by its self. The only thing we have to do is get rid of the exponent of (^2). to do this, we have to take teh square root of both sides:
The square root of x^2 is x
The square root of 121 is 11
So the asnwer is x = 11
Answer:
55
Step-by-step explanation:
12 x 5 = 60
60-5 = 55
55 is not prime
It’s the letter “B” I think
