Mathematics

Svetllana [295]3 years ago
4 0

Answer:

x=-15

Step-by-step explanation:

50=-10(x+10)

Distribute 10: 50=-10x-100

Add 100 to both sides: 100+50=-10x-100+100

150=-10x

Simplify: 150/-10=-10x/-10

x=-15

What is 25.5n - 3 = 5.5n + 10.
klemol [59]
N = 13/20 or 0.65

25.5n - 3 = 5.5n + 10

Add 3 to both sides of the equation.

25.5n = 5.5n + 13

Subtract 5.5n from both sides.

20n = 13

Divide both sides by 20.

n = 13/20 or 0.65

275 miles in 5 hours

55 miles in one hour

Check

to check if im right

275×2 would be how many miles she drove in 10 hours rght ? 275×2=550

550 miles in 10 hours

we know one hour is 55 miles & 5 hours is 275 & 10 hours is 550

10 hours plus 3 hours = 13 hours right ?

55 ×3 = 165

550 +165=715

715 miles in 13 hours

Step-by-step explanation:

715÷13 to get how many miles she drove in one hour .

=55 miles in 1 hour .

then multiply 55 ×5 to get how many miles she drove in 5 hours

55×5=275

275 miles in 5 hours
