Solve for x: three fourths times x plus five fourths equals four times x

Nostrana [21]

Answer:

x equals five thirteenths

Step-by-step explanation:

To solve this, we will follow the steps below;

$\frac{3}{4}$ × x + $\frac{5}{4}$ = 4 × x

$\frac{3x}{4}$ + $\frac{5}{4}$ = 4x

$\frac{3x + 5}{4}$ = 4x

Multiply both-side of the equation by 4

$\frac{3x + 5}{4}$ × 4= 4x × 4

On the left-hand side of the equation 4 will cancel-out 4, thus the equation becomes;

3x + 5 = 16x

subtract 3x from both-side of the equation

16x - 3x = 5

13x = 5

Divide both-side of the equation by 13

$\frac{13x}{13}$ = $\frac{5}{13}$

(On the left-hand side of the equation 13 at the numerator will cancel-out 13 at the denominator while on the right-hand side of the equation 5 will be divided by 13)

x = $\frac{5}{13}$

x equals five thirteenths

The following annual expenses for car insurance, vacation, and home repairs for the Clark family are $1130, $700, and $468, resp

eimsori [14]

Answer:

A) $192

Step-by-step explanation:

Given:

Yearly expense of Car insurance = $1130

Yearly expense of Vacation = $700

Yearly expense of home repairs = $468

we need to find the monthly allowance of Clark family.

First we find the total annual expense of Clark family.

Total Annual expense is equal to sum of Yearly expense of Car insurance and Yearly expense of Vacation and Yearly expense of home repairs.

Framing in equation form we get;

Total annual expense = $\$1130 + \$700+\$468 = \$2298$

Now we know that;

Number of months in a year = 12 months.

Total Monthly allowance will be equal to Total annual expense divided by Number of months in year.

Framing the equation we get;

Total Monthly allowance = $\frac{\$2298}{12}= \$191.5$

Rounding to nearest dollar we get;

Total Monthly allowance of Clark family is $192.

Charisse is buying two different types of cereals from the bulk bins at the store. Granola costs $2.29 per pound and muesli cost

valentina_108 [34]

Even though im not giving you grapahs, I can explain you the situation and I can shed you light inot this. Pay attention. Giveen the data we are going to use it like this <span>2.29x + 3.75y <= 7.00. Remember, you can't spend more money than 7.00, so whatever you buy has to be within 7.00$ or equal 7.00$. Since you're buying in pounds, and the amount varies, you have a variable there to indicate the price of each product depending on how many pounds of it you buy. Now, what you need to do is use this equation to graph and also solving part b by substituting in that value for y. I hope this can help you</span>
