If gas cost $3.00 per gallon, what factors will determine how much gas you purchase?

Goryan [66]

Answer:

If you are on a budget it depends if you want to purchase $50 or another amount, while if you want to fill up the gas tank it depends on the cars' capacity. Some cars can take up to 11 gallons of gas, so if wanting to fill up the tank you would need to spend $33.

Hope this helps!

Nikitich [7]

The longer sides are 20 kilometers, and the shorter sides are 13 kilometers.
(Length times width equals 260, and 20 times 2 plus 13 times 2 is 66.)

Answer:

A. Division property of inequality

Step-by-step explanation:,

If a, b and c are any real numbers,

By the division property of inequality,

a = b ⇒ $\frac{a}{c}=\frac{b}{c}$ ,

By the inverse property of multiplication,

$a(\frac{1}{a}) = 1$

where, 1 is multiplication identity.

By the subtraction property of inequality,

a = b ⇒ a - c = b - c

By transitive property of inequality,

a = b and b = c ⇒ a = c,

Thus, it is clear that,

Division property of inequality is used in step 4.

Option A is correct.

Step-by-step explanation:

In trapezoid ABCD, it is given that:

AE = BE & DF = CF

Hence, points E and F are the mid points of the sides AB and CD respectively.

We know that:

In a trapezoid length of the line segment joining the mid points of non parallel sides is equal to one half of the sum of lengths of the parallel sides.

$\therefore \: 4x = \frac{1}{2} \{(x + 5) + 44 \} \\ \\ \therefore \: 4x = \frac{1}{2} \{x + 5 + 44 \} \\ \\ \therefore \: 4x \times 2= \{x + 49\} \\ \\ \therefore \: 8x = x + 49 \\ \\ \therefore \: 8x - x = 49 \\ \\ \therefore \: 8x - x = 49 \\ \\ \therefore \:7x = 49 \\ \\ \therefore \:x = \frac{49}{7} \\ \\ \therefore \:x = 7\\ \\ \therefore \:4x = 4\times 7.. (\because EF = 4x)\\ \\ \: \: \: \: \: \huge \red{ \boxed{\therefore \:EF = 28}}$
