Hello!
*I'm not very good at algebra, so I am not 100% sure this is correct!*
w = cost of washer
d = cost of dryer
w + d = $586
w = d - 64
d - 64 + d = 586
2d = 586 + 64
2d = 650
d = 650 / 2 = 325
586 - 325 = 261
Check 325 - 261 = 64
So, the dryer costs $325 and because the washer is $64 less than the dryer, it costs $261.
step 1: open brackets n rmb to flip the signs
step 2 (optional): rearrange to make the equation clearer to add/minus
length of 3rd side:
(8x + 3) - (2x + 1) -(5x + 2)
= 8x + 3 - 2x -1 - 5x -2
= 8x -2x -5x +3 -1 -2
= x
Therefore, length of 3rd side is X cm.

If perimeter = 75cm,
8x +3 = 75
8x = 75-3
8x = 72
x = 9 cm
Therefore,
1st side = 2(9) +1
= 19 cm
2nd side = 5(9) +2
= 47 cm
3rd side = 9 cm
The square root of 64 is greater than the square root of 25; (square root sign) 64 > (square root sign) 25
Answer:
D) 96%
Step-by-step explanation:
If you take 96% of 28.6 you get 27.6 so it fits
First you gotta distribute.
4 (1.75y - 3.5) + 1.25y
4 * 1.75 y = 7
4* (-3.5) = (-14)
7y - 14 + 1.25y
Combine like terms
8.25y - 14
