I'm pretty sure the answer is 24
Answer:
6hrs
Step-by-step explanation:
First, we have to put the information given to us about the money they earn into an expression
let x represent the number of hours Kini and Duke work and y represent the total amount of money they earn in a week.
y(kini) = 9x + 8
y(duke) = 7.5x + 17
Now we subtract the x values and the constant values
9x - 7.5x = 1.5x
17 - 8 = 9
Make these into an equation
1.5x = 9
Divide both sides by 1.5 so x(the number of hours the both work) can stand alone.

x = 6 hrs
Answer:
37 degrees
Step-by-step explanation:
Tan x = 4.8/6.3
Tan x = 0.76
Tan^-1 (0.76) = 37 degrees
Answer:Its 75 9' 280
Step-by-step explanation:
Because its the retail price.
First, r<span>earrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : </span><span>3*(2*x-1)-(4*x+2)=0
= </span><span>3 * (2x - 1) - (4x + 2) = 0
= 2x - 5 = 0
= </span>2x-5 = 0<span> ---- </span><span>Add </span> 5 to both sides of the equation ---><span>
</span>= 2x = 5
Then you will divide both sides of the equation by 2 and get,
<span>= x = 5/2 OR 2.5
I hope this helps!</span>
