Answer:
$3.4
Step-by-step explanation:
Total amount spent by Mila equals $71.05
She bought 5 yards of fabric at $12.85 per yard. Hence, the total amount she spent on fabric is 12.85 × 5 = $64.25
It should be noted that since she bought only 2 kinds of things, this mean that Amount spent of fabric + Amount spent on thread = $71.05
Amount spent on thread = $71.05 - Amount spent on fabrics.
Amount spent on thread = $71.05 - $64.25 = $6.8
This is the total amount spent on thread.
But the question asks amount spent on one spool of thread. Since 2 spools would cost $6.8, one spool would cost $6.8 ÷ 2 = $3.4
D
just subtract 14 from 26
Answer:
x = -1 and y = -1
Step-by-step explanation:
to solve this equation we say
let
2x-5y=3.......................................... equation 1
4y-x=-3............................................equation 2
from equation 2
4y-x=-3............................................equation 2
4y + 3 = x
i.e
x = 4y + 3 ............................................. equation 3
put x = 4y + 3 in equation 1
2(4y +3) - 5y = 3
8y + 6 -5y = 3
3y +6 = 3
3y= 3-6
3y -3
divide both sides by the coefficient of y which is 3
3y/3 = -3/3
y = -1
put y = -1 into equation 3
x = 4y + 3 ............................................. equation 3
x = 4(-1) + 3
x = -4 + 3
x = -1
therefore the value of x = -1 and y = -1 respectively
