Suppose a car uses one gallon of gasoline for every 20 miles traveled.
anzhelika [568]

The miles that can be travelled in the car on $30 gasoline is 240 miles (option A).

<h3>How many miles can the car travel?</h3>

The first step is to determine the total gallons in the car. The total gallons in the car can be determined by dividing the total value of the gasoline the car by the cost per gallon. Division is the process of determining the quotient of two or more numbers.

Total gallons = total value of gasoline in the car / cost per gallon

$30 / $2.50 = 12 gallons

The next step is to determine the total miles that the car can travel using the gallons available. To determine the total miles, multiply the total gallons by the number of miles that that one gallon can cover.

Total miles = miles one gallon can cover x total gallons in the car

12 x 20 = 240 miles

Given that 2x + 7 equals 27 and 3x + 1 equals 28 does 2x + 7 equals 3 x + 1
ICE Princess25 [194]
2×+7=27
2×-7=27-7
2× =20
2/× =20/2
× = 10
2(10)+7=27


3×+1=28
3×-1=28-1=27
3× =27
3/× =27/3
× =9
3(9)+1=28

27 does not equal 28
so no

Graph the image of Kite BCDE after a translation 5 units down.​
NeTakaya

Answer:

See attachment for the translated kite

<em></em>

Step-by-step explanation:

Given

The attached image of BCDE

Required

Translate 5 units down

From the attachment;

B = (-7,0)

C = (0,5)

D =(-7,10)

E = (-10,5)

The rule to translate 5 units down is:

(x,y) \to (x,y-5)

So:

B' = (-7,-5)

C' = (0,0)

D' = (-7,5)

E' = (-10,0)

What is the relationship between the magic constant (the sum of each row) and the sum of all the numbers in the square? Why does
NARA [144]

Let's say each row sums to 15

If we had 3 rows, then the total sum would be 3*15 = 45

If we added all of the values in the 3x3 magic square, then we'd get 45 as well.

This is one example showing that

sum of all values = (number of rows)*(magic constant)

You can replace "rows" with columns to get the same idea, because each column also adds to the same magic constant. The diagonals are an exception since we only have two of them.
