Answer:
Option A
Step-by-step explanation:
–5x – 9y = 28 Equation 1
–4x + 5y = –2 Equation 2
We to eliminate one of the variables. In this case "Y" by using the appropiate number, in this case
–5x – 9y = 28
*{–4x + 5y = –2
We have:
–5x – 9y = 28
We have:
–5x = 28
So, We have:
-61X= 122
Using Equation 2. We have:
-4*(-2)+5Y=-2
8+5Y=-2
5Y=-10
Y=
Finally:
X=-2
Y=-2
Answer:
1. 11
2. 5.65685...~ 5.7
3. 4.2426...~ 4.2
4. .75
Step-by-step explanation:
1.) 11*11=121
2.) 5*5=25, 6*6=36
So the answer is between 5 and 6. It is closer to 6^2 than 5^2. I used a calculator to figure out the exact answer.
3.) 54/3=18, 4^2=16, 5^2=25
It is closer to 4^2 than 5^2. about 2/9 off (between the two answers). 4.242...
4.) 9/16= .5625. √.5625= .75
Hope this helps:) Have a good day!

Root square of 3 is 1.732, the root square of Pi is 1.77, the root square of 8 is 2.82 and the estimated value of Pi itself is 3.14.
Anthony's OT pay will be $118.875 and his overall pay will be $752.875.
Number of hours Anthony has to work in a week = 5 × 8 = 40 hours.
He worked for = 47.50 hours.
Overtime = 47.50 hours - 40 hours = 7.50 hours
Pay per hour = $15.85 / hour
Overtime pay (OT pay) = $15.85 × 7.50 = $118.875
Overall pay = $15.85 × 47.50 = $752.875
Therefore, Anthony's OT pay is $118.875 and his overall pay is $752.875.
