Answer:
x=105 and y=190
Step-by-step explanation:
4x+1y=610, and x+y=295 ; x= 105 and y=190
Answer:
5
Step-by-step explanation:
For this case, the first thing we must do is define variables:
x = number of quarters
y = number of dimes
We now write the system of equations:
x + y = 28
0.25x + 0.10y = 4.05
Solving the system of equations we have:
x = 8.33
y = 19.66
Rounding:
x = 8
y = 20
Answer:
the college student has:
8 quarters
20 dimes
Answer:
p(a) = -3/20
Step-by-step explanation:
p ( a +b) = p(a)+p(b)
1/10= p(a) +1/4
1/10 - 1/4 = p(a)
p(a) = -3/20
