5(2x-3)=155 solve for x

Answers

5(2x-3)=155
10x-15=155(solve/multiply 5 by the numbers/variables in the parentheses first)
10x=170(add 15 to each side)
Divide 170 by 10x
170÷10x=17
x=17

5(2x - 3) = 155
10x - 15 = 155
10x = 155 + 15
10x = 170
x = 170/10
x = 17

A car travels 120km at a certain speed. If the journey takes 2 1/2{Two and the half hours}, find the average speed{Let the speed be v km/h}

Answers

Answer:

48 km/h

Step-by-step explanation:

Distance = 120 km

Time = 2½ h

Speed = ?

We know that

Speed = Distance/Speed

Let,

Speed = v km/h

=> v = 120/(2½)

=> v = 120/(5/2)

=> v = 120 × 2/5

=> v = 24 × 2

=> v = 48 km/h

Average speed is 48 km/h
