2x+3y = 15 x-3y=3 Solve

Mathematics

Arada [10]3 years ago

By process of elimination. 3y and -3y get eliminated. Giving you

3x=18

Divide by 3 on each side

Giving you x=6

Plugging it into equation 2 you get

(6)-3y=3

Taking out the parenthesis you have

6-3y=3

Subtract by 6 on each side giving you

-3y=-3

Divide by -3 on each side giving you

y=1

So the answer for this equation is x=6 and y=1 or the ordered pair (6,1)

Write the following comparison as a ratio reduced to lowest terms.<br><br> 88 quarters to 30 dollars
LUCKY_DIMON [66]
You need to find common factors. The factors of 88 are 1 and 88, 2 and 44, 4 and 22, and 8 and 11. The factors of thirty are 1 and 30, 2 and 15, and 5 and 6. The greatest common factor is 2 so the ratio is 44:15.

Jim worked 40 hours last week, plus 8 overtime hours at the time-and-a-half rate. His gross pay was $884. A. What was his hourly
marishachu [46]

Answer:

Hourly rate: $17.

Hourly overtime rate: $25.5.

Step-by-step explanation:

Let x represent Jim's hourly pay.

We have been given that Jim worked 40 hours last week. So amount paid in 40 hours would be 40x.

We are also told that his over time pay is time-and-a-half rate that is 1.5x.

The amount earned for working 8 overtime hours would be 8\cdot 1.5x=12x.

Since Jim's gross pay was $884, so we will equate amount earned in 40 hours and 8 hours of overtime with 884 as:

40x+12x=884

52x=884

\frac{52x}{52}=\frac{884}{52}

x=17

Therefore, Jim's hourly rate is $17.

Overtime rate would be 1.5x\Rightarrow1.5(17)=25.5

Therefore, Jim's hourly overtime rate is $25.5.
