A man purchased a magazine at the airport for $2.69. The tax on the purchase was $0.13. What is the tax rate at the airport? The

alexdok [17]

We need to find the percent, let's start but making the equation.

The price is 2.69

The tax cost is 0.13

So what percent of 2.69 is = 0.13.

Equation: X/100 x 2.69 = 0.13

Multiply each side by 100 so we can get x alone with the price: 2.69x = 13

Now to get x alone, we must divide both sides by 2.69: x = 4.8

Finally, we just round 4.8 to the nearest whole number, which is 5 (5 or above give it a shove, 4 or below let it go, we have 8 so we give it a shove). This means that the answer will be 5%.

I hope this helps! :)

The sum of 2 numbers is 84 if one number is 4.less than the other find the numbers

artcher [175]

Answer:

one number= x = 44

the other number= (x-4)= 40

Step-by-step explanation:

one number= x

the other number= (x-4)

x + (x-4) = 84

2x= 84+4

2x= 88

x= 88/2= 44

one number= x = 44

the other number= (x-4)= 40

Write a slope-intercept form of the equation if it passed the

inna [77]

Answer:

$\sf\longrightarrow \boxed{\pink{\sf 3x + 4y -8=0}}$

Step-by-step explanation:

We need to write the slope intercept form of the equation which passes through (4,-1) and parallel to the line y = -3/4x .

We know that the line parallel to a given line has the same slope . Therefore the slope of the line will be , ( on comparing to Slope Intercept Form ) .

$\sf\longrightarrow Slope =\dfrac{-3}{4}$

On using point slope form ,

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

Substitute the respective values ,

$\sf\longrightarrow y - (-1) = \dfrac{-3}{4}( x - 4 )$

Simplify ,

$\sf\longrightarrow y +1 = \dfrac{-3}{4}x + 3$

Multiply both sides by 4 ,

$\sf\longrightarrow 4y + 4 = -3x + 12$

Put all terms on same side , i.e. on LHS ,

$\sf\longrightarrow \boxed{\pink{\sf 3x + 4y -8=0}}$

Hence the equation of the line is 3x + 4y - 8 = 0.

Tori takes his dog to be groomed. The fee to groom the dog is $75 plus 6.75% tax. Is 80$ enough to pay for the service?

zhannawk [14.2K]

Ok, so if you have $75 and have to pay a % of tax, you move the decimal two spaces to the left then multiply the decimal by 75. So, .0675x75= $5.06 tax, then add 5.06 and 75 which is $80.06, so he does not have enough to pay.
