If a car travels 123 miles in 3 hours, how many miles will the car drive in 5 hours help?

Answers

Answer 1

Answer: 205 miles in 5 hours

Step-by-step explanation:

The way to find our answer is to first find how many miles the car can go in one hour. We would se the equation (123 divided by 3 to find our answer) which would give us 41 miles per hour. Then, we would proceed to multiply 41 by 5 which would give us our answer, 205 miles in 5 hours. Please correct me if I'm wrong!

Answer: x=9

Step-by-step explanation:

Step 1: Subtract 2x from both sides.

3x−4−2x=2x+5−2x

x−4=5

Step 2: Add 4 to both sides.

x−4+4=5+4

x=9

Answer is 9

3x-4= 2x+5
+4 +4
——————
3x= 2x+9
-2x -2x
——————-
1x or (x) =9

Decimal: .3                          Decimal: .4              

Fraction: 3/10                       Fraction: 4/5            

Ratio: 30/100                        Ratio: 40/100

2. You are finding the whole

Ways to solve

40% of 20 = 0.4 × 20 = 8  or

40% of 20 = 2/5 x 20 = 2/5 x 20/1 = 40/5

40/5

40/5 = 8/1

40% of 20 = 0.4 x 20 = 8.0

40% of 20=8.0

3. You are finding the part

  4 divided by 5 equals=0.8 or

Percent : 30%

Decimal: .8

Fraction: 4/5
