Answer:
60 smaller vehicles had been washed
Step-by-step explanation:
1) Equation: 10y+5n=800, substitute the number of larger cars into the equation
2) 10x50 +5n=800
3)500+5n=800
4)5n=300
5)n=60
Answer:
x = -5/11
Step-by-step explanation:
2x - 4x-7x-2x =10-7+3-1
Combine like terms
-11x = 5
Divide each side by -11
-11x/-11 = 5/-11
x = -5/11
The answer to the equation is N>14
Answer:
<em>C. 94</em>
Step-by-step explanation:
Take in account for PEMDAS: Parenthesis, Exponent, Multiplication/Division, Addition/Subtraction.
First is to find the answer within the innermost parenthesis:
(4²+1).
Find the exponent of 4², which is 16, leaving you the equation of
16+1, which equals to 17.
Next you multiply 3 by 17 (since the parenthesis of 17 borders 3):
17×3=51.
Next, multiply 51 by 2 (same rule as 3×17).
51×2=102.
After this you get 102-2³. Now, find 2³=2×2×2=8
This gets you to 102-8, ending up with your answer of 94.
