For this case, the first thing we must do is define variables.
We have then:
x = number of dimes
y = number of quarters
We write the system of equations:
0.10x + 0.25y = 4.55
x = y
Solving the system we have:
x = 13
y = 13
The value of the dimes is:
(0.10) * (13) = 1.3 $
Answer:
The value of only the dimes is:
1.3 $
Inside the square root shouldn't be negative, so x must be negative in order to form positive number inside the root.
if x = 0, y = 0
if y = -1, y = -1
if y = -4, y = -2
if y = -9, y = -3
the points lie on the graph (0,0), (-1,-1), (-4,-2), (-9,-3)
I think the answer is 0.04...
Answer:
x = -180
Step-by-step explanation:
0 = 0.65x + 117
-117 = 65x/100
cross-multiply to solve for 'x':
65x = -11700
x = -11700/65
x = -180
