A) .05n + .10d + .25 q = 10.30
B) d +2 = q
C) n = 3q
Substituting equations B and C into A
A) .05*3q + .10(q-2) + .25 q = 10.30
A) .15q + .1q -.2 + .25q = 10.30
A) .50q = 10.50
21 quarters
C) n = 3q
C) n = 3*21
63 nickels
B) d +2 = q
d + 2 = 21
19 dimes
Answer:
Step-by-step explanation:
We have to simplify this equation.
<u>Like this:</u>
<u>The closest number to x is 19:</u>
<u>Solve:</u>
- 2 * 19 + 8 = 46
- = 38 + 8 = 46
- = 46.
x = 19.
Move 6x to the right side
2y = -6x - 14
Divide all numbers by 2 to isolate the variable
2y/2 = -6x/2 - 14/2
y = -3x - 7
Answer:False
