Answer:
-6
Step-by-step explanation:
-6/b-50=-49
step1;collect like terms
-6/b=-49+50
-6/b=1
step2;cross multiply
-6/b=1
-6=1b(1b can also be regarded as b)
b=-6
Answer:
Divide both sides by 2
Step-by-step explanation:
We have the equation
2(x + 14) = 40
We divide both sides by 2
2(x + 14) = 40/2
x + 14 = 20
x = 20 - 14
x = 6
Therefore, the most helpful first step for solving Ravi's equation is: Divide both sides by 2
Answer:
4
Step-by-step explanation:
Simplify the following:
2^5/2^3
Hint: | For all exponents, a^n/a^m = a^(n - m). Apply this to 2^5/2^3.
Combine powers. 2^5/2^3 = 2^(5 - 3):
2^(5 - 3)
Hint: | Subtract 3 from 5.
5 - 3 = 2:
2^2
Hint: | Evaluate 2^2.
2^2 = 4:
Answer: 4
