Let X = the number of pennies.
The number of nickels would be 2X
A penny is 0.01 and a nickel is 0.05
Now you have:
0.01x + 2(0.05x) = 8.80
Simplify:
0.01x + 0.10x = 8.80
Combine like terms:
0.11x = 8.80
Divide both sides by 0.11:
x = 8.80 / 0.11
x = 80
Pennies = X = 80 total pennies.
Nickels = 2x = 2 *80 = 160 nickels.
Answer:
35ab = 48
Step-by-step explanation:
given
5a = 6 ( divide both sides by 5 )
a = 
and
7b = 8 ( divide both sides by 7 )
b = 
substitute these values for a and b into the expression and simplify
35ab
= 35 ×
×
( divide 35 and 5 by 5 )
= 7 × 6 × 
= 42 ×
( divide 42 and 7 by 7 )
= 6 × 8
= 48
