slega [8]

Answer:

-12

Step-by-step explanation:

Let the number be A

Given if you divide the sum of six and the number A by 3 , the result is 4 more than 1/4 of A

That’s

6+A/3 = 4+1/4 of A

6+A/3 = 4+1/4 x A

6+A/3 = 4+A/4

Cross multiply

4(6 + A) = 3(4 + A)

Distribute

4 x 6 + 4 x A = 3 x 4 + 3 x A

24 + 4A = 12 + 3A

Subtract 24 from both sides to eliminate 24 on the left side

24 - 24 + 4A = 12 - 24 + 3A

4A = -12 + 3A

Subtract 3A from both sides so the unknown can be on one side

4A - 3A = -12 + 3A - 3A

A = -12

Check

6+(-12)/3 = 4 +(-12)/4

6 -12/3 = 4 -12/4

-6/3 = -8/4

-2 = -2

Natali5045456 [20]

Answer:

The money left after gasoline expenses was $622.50.

Step-by-step explanation:

Given:

Last month, family had used 40% of the monthly income for gasoline, and 63% of that gasoline was consumed by the family's SUV.

The family's SUV used $261.45 worth of gasoline previous month.

Now, to find the money left of the family monthly income after gasoline expenses.

Let the total money spend on gasoline be $g.$

As, given:

The family's SUV used $261.45 worth of gasoline, which was 63% of the gasoline that was consumed.

According to question:

$63\%\ of\ g=$261.45.\\\\$

$\frac{63}{100} \times g=261.45\\\\0.63\times g=261.45$

Dividing both sides 0.63 we get:

$g=\$415.$

The total money spend on gasoline = $415.

Now, 40% of the monthly income is used for gasoline.

Let the total monthly income be $x.$

So, to get the monthly income we put an equation:

$40\%\ of\ x=\$415\\\\\frac{40}{100}\times x=415\\\\0.40\times x=415$

Dividing both sides by 0.40 we get:

$x=\$1037.50.$

The total monthly income = $1037.50.

Now, to get the money left after gasoline expenses we subtract the total money spend on gasoline from the total monthly income:

$\$1037.50-\$415\\\\=\$622.50.$

Therefore, the money left after gasoline expenses was $622.50.
