Answer:
32 hours
Step-by-step explanation:
First setup an equation
500 + 22x = 1204 the x represents how many hours she worked an that is what we want to know. So to find out x you do this......
22x + 500 = 1204
1204-500= 704
704/22 = 32
So, X = 32 hours
Answer:
Some keywords include "starting amount," you should look out for this because it will be the y-intercept for the equation. Another keyword may be "daily" or "monthly" or "yearly," which would be the coefficient of x, or the amount that y increases with an increase of 1 in x.
pls mark brainliest :)
Angle C is 40degree
Then Angle B is supposed to be 180-90-40 which will be 50 degree
Let us say that:
x = hours worked by Wolfgang
y = hours worked by Heinrich
So that:
x = y + 10
14 x + 12 y = 3520
By combining the two equations:
14 (y + 10) + 12 y = 3520
14 y + 140 + 12 y = 3520
26 y = 3380
y = 130 hours
x = y + 10 = 140 hours
<span>So Wolfgang worked 140 hours while Heinrich worked 130
hours.</span>
There are no values of X that make the equation true therefore there is no solution
