Answer:
8y+6y=288
Step-by-step explanation:
8y+6y= 12y
12y=288
12y divide by 12 = 288 divided by 12 =
y=24
Answer: 
Step-by-step explanation:
Given
Rectangle has an area of 
Suppose rectangle length and width are
and 
If each side is increased by 
Area becomes 
We can write

Substitute the value of width from (ii) in equation (i)

Width corresponding to these lengths

Therfore, we can write the length of the longer side is 
No, because 3/2 is actually 1 1/2. 2/3 isn't even 1
Answer:
y=4
Step-by-step explanation:
2(y+1)-2=4+y
2y+2-2=4+y
2y=4+y
2y-y=4
y=4
Answer:
Step-by-step explanation:
d = number of dimes
2.80 = 0.1d + 0.25 (d + 8 )
2.80 = 0.1d + 0.25d + 2 Combine like terms
2.80 = 0.35d + 2 Subtract 2 from both sides
0.80 = 0.35d Divide both sides by 0.35
d ≈ 2.29
No, it's not possible to have more quarters than dimes when the total is $2.80 because it's not possible to have part of a dime.
