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

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

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
