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.

Answer:

$\huge \boxed{y=14x}}$

Step-by-step explanation:

x=0.5, y=7

x=1, y=14

x=1.5, y=21

x= 2, y=28

Let’s take the first equation.

y = 14x

y = 14(0.5) = 7

When x is 0.5, y is 7.

y = 14(1) = 14

When x is 1, y is 14.

y = 14(1.5) = 21

When x is 1.5, y is 21.

y = 14(2) = 28

When x is 2, y is 28.

** HELP ASAP!! **write an equation in slope intercept form of the line that has a slope = -3/2, and passes through the point (-3

rewona [7]

Given :-

Slope of the line is -3/2 .
It passes through (-3,3) .

To Find :-

The equation of the line .

Solution :-

Here it's given that ,

$\longrightarrow m =\dfrac{-3}{2}$

And a point that is (-3,3) . We can use the point slope form of the line which is ,

$\longrightarrow y - y_1 = m(x - x_1)$

Substituting the respective values,

$\longrightarrow y - 3 = \dfrac{-3}{2}\{ x -(-3)\}$

Simplify,

$\longrightarrow y -3 = \dfrac{-3}{2}( x +3)$

Simplify by opening the brackets ,

$\longrightarrow y - 3 =\dfrac{-3}{2}x -\dfrac{9}{2}$

Add 3 on both sides ,

$\longrightarrow y = \dfrac{-3}{2}x -\dfrac{9}{2}+3$

Add ,

$\longrightarrow \underline{\underline{ y =\dfrac{-3}{2}x -\dfrac{3}{2}}}$

This is the required answer in slope intercept form .
