Answer:

y = 1/2 - 5

Step-by-step explanation:

This doesn't fit any of the answer choices, but none of them are right. It says a slope of 1/2 NOT negative, right? And a y-intercept of -5. This isn't in any of the answer choices. I guess it might be looking for the first answer choice, but again, the slope there is negative when the question does not say negative.

How do you create your equations when working on a mixture word problem?

Let's try to think about the general form of a word problem involving mixtures.

In general, we have the following scenario:

a merchant sells two kinds of products (coffee, sweets, etc).

we know the unit prices for both kinds of products and for the final mixture

US dollars per pound for the first kind of product,

US dollars per pound for the second kind of product

US dollars per pound for the mixture

we know the total quantity formed by the mixture of the two products (

pounds)

we have to find out the quantities of each product needed to form the mixture

(here we have the variables:

denoting the quantity of the first kind of product and

denoting the quantity of the second kind of product)

Now, we have sufficient information to work out the equations.

First, we know that the sum of the two quantities is

pounds, which gives us the first equation:

Second, we know that the sale price is the product of quantity and unit price, which gives us the second equation:

⋅

Now, we have a system of two linear equations that can be easily solved by substitution.

$2 \frac{5}{8} \div 2 \frac{1}{2}$
Change the mixed fractions to improper fractions.
To do this, multiply the whole number part by the denominator. Add that to the numerator. Then write the result on top of the denominator.

You would now have:
$\frac{21}{8} \div \frac{5}{2}$
Change the division sign to a multiplication sign by turning the second fraction upside down.
That is,
$\frac{21}{8} \times \frac{2}{5}$

The answer is:
$\frac{42}{40}$

This can be simplified to:
$\frac{21}{20}$

4(5x - 2) = 72<br> What do I do

Pepsi [2]

Answer:

x = 4

Step-by-step explanation:

4(5x - 2) = 72

Do the distributive property

20x - 8 = 72

Then add 8 to both sides to get 20x alone

20x - 8 = 72

+ 8 + 8

20x = 80

Then divide both sides by 20 to get x

$\frac{20x}{20} = \frac{80}{20}$

x = 4
