Answer:
$7.15
Step-by-step explanation:
The best way to solve this is by crossing out the data you don't need so you're left looking at the key pieces to put the equation together. If his dad paid him $45.76 for 6.4 hours, then all you need to do is divide 45.76 by 6.4. (Hint: Use a calculator, it makes it ten times faster than trying to write it out!)
45.76 ÷ 6.4 = 7.15
So Greg made $7.15 an hour working with his dad.

Answer:
x intercept: 15/8 and yintercerpt is 3/2
Step-by-step explanation:
to find y intercept you have to put equation in standard form.
10y=-8x+15
y=--4/5x+3/2
x intercept is when y=0, so we plug in 0
0=-4/5x+3/2
4/5x=3/2
x=15/8
divide how much it was reduced ( 5) by the original price(35)
5/35 = 0.14285, now turn that into a percent so about 14.3%
The correct answer is C. 65
Explanation:
The serving size of the soft drink is 8oz, besides this, the amount of sugar for this serving size according to the label is 26 grames. Now, to calculate the amount of sugar in 20oz, one of the simplest methods is to use a rule of three, because three values are known, and one is missing. The process is shown below:
1. Write the known values and use x to represent the unknown values
8 oz = 26 grames of sugar
20 oz = x
2. Use cross multiplication (this means multiply 8 x 6) and divide it into the remaining value
or x = 26 x 20 / 8
3. Solve the equation
or x = 520 / 8
