PLS HURRY HAVE 10MIN. LEFT

Andre45 [30]

Answer:

Step-by-step explanation:

Let the tenth digit is x and units digit is y.

We have the following equations:

y = x + 5
(x + y)*3 = 10x + y

Simplify the second equation:

3x + 3y = 10x + y
2y = 7x

Solve by substitution:

2(x + 5) = 7x
2x + 10 = 7x
7x - 2x = 10
5x = 10
x = 2

Find y:

y = 2 + 5
y = 7

The number is 27

Maralah can drive her car 580 miles at a steady speed is in 20 gallons of gasoline. Make a rate table to show the number of mile

Aliun [14]

Total distance traveled in 20 gallons of gasoline = 580 miles

Total distance traveled in 1 gallon of gasoline = $580\div 20$

= 29 miles

Now, we have to calculate the number of miles Maralah can drive in 2,3,4,5,6,7,8,9 ans 10 gallons of gasoline.

Since, number of miles traveled in 1 gallon of gasoline = 29 miles

Number of miles traveled in 2 gallons of gasoline = $29 \times 2$ = 58 miles.

In the similar way, we will make a table which shows the number of miles she can drive her car for 1,2...10 gallons of gasoline.

Refer to the table in attached image.
