It takes Bruce 12 h to complete his training. It takes Oliver approximately 2 days, 2 h, and 15 min to complete his training. Ho

Bond [772]

Answer:

Oliver completed his training work in 50.25 hours

Step-by-step explanation:

we know that

$1\ day= 24\ hours$

$1\ hour=60\ minutes$

we have

$2\ days, 2\ h,\ and\ 15\ min$

Convert days to hours

$2\ days=2(24)=48\ hours$

Convert minutes to hour

$15\ min=15(1/60)=1/4=0.25\ h$

$2\ days, 2\ h,\ and\ 15\ min=(48)+(2)+(0.25)=50.25\ h$

therefore

Oliver completed his training work in 50.25 hours

I really need help asap please

We can use the substitution method to solve this problem.

The second equation is $\sf y=2x$ , so we can plug in 2x for 'y' in the first equation:

$\sf 5x-2y=3$

$\sf 5x-2(2x)=3$

Multiply:

$\sf 5x-4x=3$

Combine like terms:

$\sf x=3$

This is the x-value of our solution, we can plug this into any of the two equations to find the y-value:

$\sf y=2x$

$\sf y=2(3)$

Multiply:

$\sf y=6$

This is the y-value of our solution. So our entire solution is (3, 6).
