Answer:
75
120
Step-by-step explanation:
Let the first mechanic's hourly rate = x
Let the second mechanic's hourly rate = y
x + y = 195
15x + 5y = 1725 Divide this equation by 5
3x + y = 345 Write the first equation below this one. Subtract
<u>x + y = 195</u>
2x = 150 Divide by 2
x = 150/2
x = 75
====================
x + y = 195
75 + y = 195
y = 195 - 75
y = 120
30 10s would be a hundred multiplying it so there are 3 of 100 in 300

Answer:
x = sqrt (22)
Step-by-step explanation:
This is a RIGHT triangle with the two legs of equal length sqrt 11
us pythagorean theorem
a^2 + b^2 = c ^2 where a and b are the legs and c = hypotenuse
(sqrt11)^2 + (sqrt11)^2 = x^2
11 + 11 = x^2
x = sqrt (22)
