Answer:

Amount of gas = 3.2 gallons

Required coordinate pair is (3.2, 12)

Step-by-step explanation:

Let x be the number of gallon of gas.

Given:

Berto has ⇒ y = $12

Gas cost per gallon ⇒ $3.75

Solution:

Using below formula.

Number of gallon of gas = $\frac{Total\ cost}{Gas\ cost\ per\ gallon}$

Now, we substitute total cost and gas cost per gallon.

$x=\frac{12}{3.75}$

$x=3.2\ gallon\ of\ gas$

Therefore, Berto can buy 3.2 gallon of gas and required coordinate pair is (3.2, 12).

Andre45 [30]

Answer:

Step-by-step explanation:

Let

Point 1 ----------> (5, 2)

Point 2 ----------> (–6, 2)

we know that

the distance between two points it is calculated with the formula

d=√[(y2-y1)²+(x2-x1)²]

then

d=√[(2-2)²+(-6-5)²]

d=√[(0)²+(-11)²]

d=√[121]

d=√121-----------> d=11 units

the answer is 11 unit
