Answer:
(5,-3)
Step-by-step explanation:
9x+2y=39
6x+13y=-9
---------------
117x+26y=507
12x+26y=-18
----------------------
105x=525
x=5
Substitution
9(5)+2y=39
45+2y=39
2y=-6
y=-3
4b+1 equivalent to -2(b+4)+3
6-4=2
5-X=?
5-2=3
X=3
That is the answer, sorry if i didn't explain it well<span />
Answer:
She sneezed for 138.286 weeks in a row. You need days of week to create a proper conversion.
Step-by-step explanation:
There are 7 days in a week. There are 978 days shown.
You can depict it as this:
978 = 7x; x is the amount of weeks.
Divide both sides by 7
138.285714 = x
Round to three decimals
x = 138.286

Step-by-step explanation:
Taylor cannot spend over $260.
Subtract the cost of the part needed for the repair:
= 260 - 80
= $180
$180 is left for fixing the car after buying the part.
As the labor costs $30 and now she cannot exceed $180 for labor, the total number of hours the mechanic can work is:
= 180 / 30
= 6 hours
