The first step to this is to subtract 7 from both sides. The +7 and -7 cancel each other out leaving you with 3x=6 then divide by 3 on each side giving you x=2.
Let's say that Bob is x and James is y
x + y = 180
x = 2y
2y + y = 180
y = 60.
James spent 60 dollars.
Answer:
28
Step-by-step explanation:
- 28 is a multiple of 7, multiply it by 2 is 56 and it is greater than 22.
if you find another answer too, let me know
$4,200 / .12 =$35,000 her salary this year.
$35,000 - $3,000=$32,000 Her salary last year.
An equation representing this would look something like this:
S=(C/I) - R, where, S=her salary last year, C=amount of her savings, I= rate of her savings, R=salary increase.
Answer:
y = 1/2x + 5
Step-by-step explanation:
The line has a slope of one half. If you look at the dots made, take a look at the dot on the y-axis. Then, if you move up one space from that point, and move two spaces to the right of the point, you reach the second dot. This determines the slope which would be written as 1/2x. Then, if you look back to where the line passes through the y axis, you'll see it landed on positive five. This means 5 will be added to the end of the equation. So, y equals the slope plus the y-intercept. y = 1/2x + 5
