espero que esto ayude
No sé si es del todo correcto, ¡pero que tengas un buen día!
2 times the cube root of 8x+9=5
divide both sides by 2
cube root of 8x+9=2.5
cube everybody (put to 3rd power)
8x+9=2.5^3
8x+9=15.625
minus 9 both sides
8x=6.625
divie both sides by 8
x=0.828125
Answer:
a). The equation; 7.25 h-36.25=0
b). total number of hours Steven work=5 hours
Step-by-step explanation:
Part A
The expression for the total money earned is as follows;
T=E×h
where;
T=total earnings
E=earnings per hour
h=number of hours worked
In our case;
T=$36.25
E=$7.25
h=h
replacing;
36.25=(7.25×h)
36.25=7.25 h
The equation would be; 7.25 h=36.25, or 7.25 h-36.25=0
Part B
7.25 h=36.25
h=36.25/7.25
h=5
total number of hours Steven work=5 hours
