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

Answers
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:
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

Adjacent is x
So tangent of 18 degrees = 18/x
Use calculator to find tangent of 18 =0.3249
So 0.3249 = 18/x
Reciprocal both sides
3.0777 = x/18
Multiply both sides by 18
