Subtract from both sides by 3/8, and u got -1/8. If u want to check put -1/8 in a
-1/8+3/8=1/4
Answer:
x= 30/ 17
Step-by-step explanation:
Answer:
He gave 8.57 % of his money for his cousin.
Step-by-step explanation:
In order to calculate the percent that Pedro gave to his cousin, we first need to calculate his total amount, which is given by "x". This is given by:
x = 15 + (x - 15)/5 + 128
x = 15 + x/5 - 3 + 128
x = x/5 + 140
x - x/5 = 140
(5*x - x)/5 = 140
4*x = 700
x = 175
He had originally $175 and gave $15 to his cousing, therefore we can use a rule of three to calculate the percent that he gave to his cousin:
$175 -> 100%
$15 -> y%
175*y = 1500
y = 1500 / 175
y = 8.57 %
I believe the answer is A
Answer:
y= 2/3x +1
Step-by-step explanation:
The y intercept is 1 It crosses the y axis at 1. So the point is (0,1)
Another point on the line is (3,3)
We can calculate the slope
m = (y2-y1)/(x2-x1)
= (3-1)/(3-0)
=2/3
The equation for a line is y=mx+b where m is the slope and b is the y intercept
y= 2/3x +1
