Juan sells 3 oranges for every 2 apples. How many apples should Juan expect to sell
when Juan sells 15 oranges:
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
Answer:
He can expect to sell 10 apples

Step-by-step explanation:
Answer:
137 [tex]ft^2[/tex]
Step-by-step explanation:
1. Approach
Break up the given figure into smaller figures. One can break up this figure into a rectangle, and a triangle. After doing so, one can calculate the area of each of the smaller figures, and then add up the values.
2. Calculate the area of the triangle
If one were to cut the top figure off, one would get a triangle with a base of (3ft), and a height of (6ft). One can calculate the area of the figure using the formula;
[tex]\frac{base*height}{2}[/tex]
Substitute;
[tex]\frac{6*3}{2}\\\\= \frac{18}{2}\\\\\ 9[/tex]
3. Calculate the area of the rectangle;
Now, one is left with a rectangle with dimensions (16ft), and (8ft). To find the area of this figure, use the formula;
[tex]base * height[/tex]
Substitute;
[tex]16 * 8\\\\= 128[/tex]
4. Find the area of the whole figure
Now add the area of the triangle, and the area of the rectangle together.
(Rectangle) + (Triangle)
= 128 + 9
= 137

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
Whoever gets this correct gets brain, 5 stars and a thanks! An explanation of it would be amazing! Tysm!
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)
[tex]\frac{1}{4} = 0.25\\[/tex][tex]\frac{3}{5} = 0.60[/tex]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.
[tex]\frac{broccoli}{fiber} =\frac{0.25}{0.60}[/tex]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".
[tex]\frac{broccoli}{fiber} =\frac{5}{x}[/tex]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
[tex]0.25x = 5(0.60)[/tex][tex]0.25x = 3[/tex]5) Then at last, divide both sides by [tex]0.25[/tex] and you'll get:
[tex]x=12[/tex]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

Aaliyah needed to get her computer fixed. She took it to the repair store. The technician at the store worked on the computer for 3 hours and charged her $66 for parts. The total was $441. Write and solve an equation which can be used to determine xx, the cost of the labor per hour.
Equation:
Answer: x =
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

Determine the equation of the line passing through the points A(–1, 6) and B(2, 4).
Answer:
y = -2/3x + 5 1/3
Step-by-step explanation:
Find the slope:
4 - 6 / 2 - (-1) = -2/3
Put it in point-slope form:
y - 6 = -2/3(x + 1)
rearrange:
y - 6 = -2/3x - 2/3
y = -2/3x + 5 1/3
