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

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

find the length of the missing side
Answer: 55.4
Step-by-step explanation:
Remember soh cah toa
tangent = adjacent/opposite
angle is 18 degrees
Opposite is 18
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
x = 55.3983
You may need to round

Suppose you make coffee and it starts off just too hot to drink, so you put it in the refrigerator temporarily to cool it off. If the original temperature is 190 degrees Fahrenheit and the refrigerator is 36 degrees Fahrenheit, what will the temperature of the coffee be after 3 minutes? (k = 0.12)
Answer:
Step-by-step explanation:
f(x)= 36( 1 - 0.12)^x. F(x)= 36(0.88)^3. f(x)= 95.04 190-95.05 = 94.95 degree.
Because the temperature is going down, we will use (1-0.12) instead of (1+0.12). X=3 because it is what temperature after 3 min. x= time.
I don't understand the question that well, but please don't report me. I will fix it if I can.
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
