Answer:
x = 3
Step-by-step explanation:
So if we plug in 3 to 7+x+(-10), it simplifys to
7+3+(-10)
10+(-10)
10-10 = 0
x=3
i dont understand
115%(15,800)= $18,170. <--- markup price
$15,800+$18,170= $33,970 total price
That is 115% x $15,800 = $18,170 markup price
Then add the original price to the markup price
That is $15,800 + $18,170 = $33,970
0.375
Convert the fraction to a decimal by dividing the numerator by the denominator.
3/8 = 0.375
y=1/5(x+37)
y=1/5x+4/5
Plug in the (3,8)
8=1/5(3)+b
8=3/5+b
7 2/5=b
