Two mechanics worked on a car. The first mechanic worked for
yuradex [85]
Create equations:
10X+15y=2575.
X+Y=210.
Solve for X: X=210-Y, and sub it into the other equation: 10(210-Y)+15Y=2575. Solve for Y: 2,100-10y+15y=2575, 5y=475, y=95.
Sub Y into the original problem: X+95=210. Solve: X=115.
The first mechanic charges $115 per hour and the second charges $95 :)

timurjin [86]

Answer:

The middle term would be 48x

Step-by-step explanation:

In order to find this, we need to take the squares of the end terms and put them in a perfect square. Then we can distribute to find the middle term.

(3x + 8)^2

(3x + 8)(3x + 8)

9x^2 + 24x + 24x + 64

9x^2 + 48x + 64

Rounded 3,428,583 rounded to the nearest 10,000
densk [106]
Since you want to round to the 10,000 place, you'll want to look at the 2 and the 8 that are next to each other. The 8 makes the two a 3 because it is greater than 5, which gives you 3,430,000. Hope this helped!
