19.18/2.8= 6.85 hours or rounded it would be 7 hours
Answer:
Step-by-step explanation:
x is the amount of hours it will take. Since he pays $30 per hour, your answer would be 30x + 525
Answer:
x= 5/4 ; y= -7/4
Step-by-step explanation:
I will solve your system by substitution.
(You can also solve this system by elimination.)
3x+y=2;5x−y=8
Step: Solve3x+y=2for y:
3x+y+−3x=2+−3x(Add -3x to both sides)
y=−3x+2
Step: Substitute−3x+2foryin5x−y=8:
5x−y=8
5x−(−3x+2)=8
8x−2=8(Simplify both sides of the equation)
8x−2+2=8+2(Add 2 to both sides)
8x=10
8x
8
=
10
8
(Divide both sides by 8)
x=

4
Step: Substitute

forxiny=−3x+2:
y=−3x+2
y=−3(

4
)+2
y=
−7
4
(Simplify both sides of the equation)
Answer:
x=

Answer:
Subtract xx from both sides of the equation.
−2y=4−x
