Answer:

D: 12

Step-by-step explanation:

1) So what I did at first was convert the fractions into decimals.

(Personally, this makes it easier, for me at least)

2) The problem states that for every 0.25 cups of broccoli, 0.60 grams of fiber are added as well to the mix. You can also convert this into a fraction. (It doesn't matter which one is the numerator/denominator, but for this example, I used the 0.25 cups of broccoli as the numerator.

3) Next step would be making another fraction. This time, the fraction is for the 5 cups of broccoli. Since we don't know the amount of grams for the fiber, we will replace it with an "x".

4) Realize, that |  [tex]\frac{0.25}{0.60} =\frac{5}{x}[/tex] |  To figure out the answer to this part, you can cross-multiply

5) Then at last, divide both sides by [tex]0.25[/tex] and you'll get:

Sorry this may have taken a long time; I just wanted to make sure everything was correct. Hope you do well on math, whether it's a test, or just homework. Good luck! :D

Question:

Three students were working on 630,000÷700 in math class.

a. Desiree finds the quotient is 9,000 and Micah finds the quotient is 900.

    Determine which student found the correct quotient.

b. Delilah finds her answer is 90, but she copied the expression incorrectly from the board. If her reasoning and answer for the expression she copied are correct, what expression might she have written?

Answer:

a. Micah is correct

b.

[tex]Expression = 63000 \div 700[/tex]

[tex]Expression = 630000 \div 7000[/tex]

Step-by-step explanation:

Given

[tex]Expression = 630000 \div 700[/tex]

[tex]Desiree = 9000[/tex]

[tex]Micah = 900[/tex]

Solving (a): Who is correct?

To do this, we first calculate the quotient of the expression.

[tex]Expression = 630000 \div 700[/tex]

Divide 630000 by 700

[tex]Quotient = 900[/tex]

Hence:

Micah is correct

Solving (b): What Delilah must have copied?

We have:

[tex]Delilah = 90[/tex]

There are no options to pick from. So, we just need to work out expressions that equals 0.

Possible expressions are:

[tex]Expression = 63000 \div 700[/tex]

[tex]Expression = 630000 \div 7000[/tex]

Answer:

x = -5, and y = -6

Step-by-step explanation:

Suppose that we have two equations:

A = B

and

C = D

combining the equations means that we will do:

First we multiply both whole equations by constants:

k*(A = B) ---> k*A = k*B

j*(C = D) ----> j*C = j*D

And then we "add" them:

k*A + j*C = k*B + j*D

Now we have the equations:

-x  - y = 11

4*x - 5*y = 10

We want to add them in a given form that one of the variables cancels, so we can solve it for the other variable.

Then we can take the first equation:

-x  - y = 11

and multiply both sides by 4.

4*(-x - y = 11)

Then we get:

4*(-x - y) = 4*11

-4*x - 4*y = 44

Now we have the two equations:

-4*x - 4*y = 44

4*x - 5*y = 10

(here we can think that we multiplied the second equation by 1, then we have k = 4, and j = 1)

If we add them, we get:

(-4*x - 4*y) + (4*x - 5*y) = 10 + 44

-4*x - 4*y + 4*x - 5*y = 54

-9*y = 54

So we combined the equations and now ended with an equation that is really easy to solve for y.

y = 54/-9 = -6

Now that we know the value of y, we can simply replace it in one of the two equations to get the value of x.

-x - y = 11

-x - (-6) = 11

-x + 6 = 11

-x = 11 -6 = 5

-x = 5

x = -5

Then:

x = -5, and y = -6

Step-by-step explanation:

Answer:

what?......................

Answer:

x=125

Step-by-step explanation:

First identify what the varible means,

x = the cost of the labor per hour.

Next, write out an equation

3x + 66 = 441

Solve,

3x+66=441

Step 1: Subtract 66 from both sides.

3x+66−66=441−66

3x=375

Step 2: Divide both sides by 3.

3x/3 = 375/3

x=125

Answer:

10 apples

Step-by-step explanation:

We can write a ratio to solve

3 oranges     15 oranges

--------------- = -----------------

2 apples           x apples

Using cross products

3x = 2 * 15

3x = 30

Divide by 3 on each side

3x/3 = 30/3

x = 10
