4. Number of dimes= d and number of quarters=q
d+q= 27
10d + 25q= 405
d= 27-q
10(27 -q) +25 q= 405
270 -10q + 25q= 405
270 + 15q= 405
15q= 135
q=9
d + q= 27
d +9=27
d=18

Answer:
(1, - 2 )
Step-by-step explanation:
Given the 2 equations
3x + y = 1 → (1)
5x + y = 3 → (2)
Subtracting (1) from (2) term by term eliminates the term in y, that is
(5x - 3x) + (y - y) = (3 - 1) and simplifying
2x = 2 ( divide both sides by 2 )
x = 1
Substitute x = 1 in either of the 2 equations for corresponding value of y
Using (1), then
3 + y = 1 ( subtract 3 from both sides )
y = - 2
Solution is (1, - 2 )
Answer : 15
to find the scale you divide. 45/3 = 15.
this gives you the scale 15
i don’t know how else to explain it but i hope this helps
Subtract 12 on both sides and both 12s cross out leaving -3m= 6 and then divide -3 on both sides and your answer should be m=-2
