Answer: =10x+8y−12
Step-by-step explanation:
Let's simplify step-by-step.
−6x−12+8y+16x
=−6x+−12+8y+16x
Combine Like Terms:
=−6x+−12+8y+16x
=(−6x+16x)+(8y)+(−12)
=10x+8y+−12
Answer:
=10x+8y−12
Answer:
Quarters = 20
Dimes = 14
Step-by-step explanation:
Dime = x = 10 cent = $0.1
Quarter = y = 25 cent = $0.25
x + y = 34 - - - (1)
0.1x + 0.25y = 6.40 - - - - (2)
From (1)
x = 34 - y
0.1(34 - y) + 0.25y = 6.40
3.4 - 0.1y + 0.25y = 6.40
3.4 + 0.15y = 6.40
0.15y = 6.40 - 3.40
0.15y = 3
y = 3 / 0.15
y = 20
x = 34 - y
x = 34 - 20
x = 14
Quarters = 20
Dimes = 14
