Answer:
$1000 per month
Step-by-step explanation:
5000 dollars is 100 percent so we put 5000 over 100
5000/100
then since we need to find 20 percent of something, we put x over 20
x/20
Then we cross multiply
<u>5000</u> times <u>x </u>
100 20
so 100x = 100000
and x = 1000
Good luck, and hope I did this correctly
Answer:
60 months
Step-by-step explanation:
20 000 = 5000 + 250 m
20 000 - 5000 = 250 m
(15 000) / 250 = m = 60 months
Answer:
x = -1
Step-by-step explanation:
3x - 10x + 5 = 5x + 17 (collect like terms)
-7x + 5 = 5x + 17 (subtract 5x on both sides)
-12x + 5 = 17 ( subtract 5 on each side)
-12x = 12 ( divide by -12 on each side)
x = -1
So if you're solving by substitution, one equation must be in slope intercept form. Ill just go with the first one.
-4x+y=6
<u>+4x +4x
</u>y=6+4x
Now substitute the value of y in for the value of y in the second equation:
-5x-(6+4x)=21
-5x-6-4x=21
-9x-6=21
<u> +6 +6
</u><u>-9x=27
</u>-9 -9
x=-3
Now input that into the first equation:
-4(-3)+y=6
12+y=6
<u>-12 -12</u>
y=-6
