Answer:
A) 10.7a - 8.1b
Step-by-step explanation:
(14.2a + 9.8b) - (13.1b - 0.2a) - (3.7a + 4.8b)
Combine like terms.
(14.2a + 0.2a - 3.7a) = 10.7a
(9.8b - 13.1b - 4.8b) = -8.1b

The answer to this question is -121584
Answer:
x= -12 & y=24
Step-by-step explanation:
given,
x+y=12.......... equation (i)
2x=3y........eq(ii)
let,
x=12-y.......eq(iii)
from eq(ii)
2(12-y)=3y
y=24
putting the value of y in eq(iii)
x=12-24
x= -12
Answer:
r = 4
Step-by-step explanation:
You need to use the slope formula to solve for r.
1. Write out the equation using slope formula
(-7 - 1)/(r + 4) = -1
2. Multiply both sides by r + 4
-8 = -r - 4
3. Add 4 on both sides. Optionally, use the reflexive property of equality.
-r = -4
4. Multiply both sides by -1
r = 4
