Answer:
The property used in the simplification is: Distributive Property.
Step-by-step explanation:
" The distributive property is used to combine the two terms that had the same variable. The distributive property is the key to combining expressions with like terms.
Terms are like terms when they have the exact same variables with the exact same exponents" .
Hence, the property used in the simplification of this expression is a distributive property.
Answer:
9 nickels
Step-by-step explanation:
Set the number of pennies as x. The number of nickels would be 31 - x.
The pennies are worth x cents and the nickels are worth 5 * (31 - x), or 155-5x.
We are given that he has 67 cents, so:
x + 155 - 5x = 67
Solve.
-4x = 67 - 155 = -88
x = 22
Nickels are 31 - x, so the number of nickels he has is 9.
I hope this helps!
Answer:
Step-by-step explanation:
Use similar triangles and proportions to solve:
and cross multiply:
4(6 + x) = 60 and
24 + 4x = 60 and
4x = 36 so
x = 9
The answer is c bc when you multiple they equal
