So all you have to do is turn the dollars into cents. And for the % you have to divide the cents you get by the %
Answer:
He could use y+3x=-4
Step-by-step explanation:
When we subtract 3x on both sides, we get y=-4-3x, which means we just solved a variable and can substitute into the other equation 2x-3y=-21
Answer:
x = (19.5 - 6y - 6z) /6
y = (19.5 - 6x - 6z) /6
z = (19.5 - 6x - 6y) /6
Step-by-step explanation:
Let the Apples be X
Oranges be Y
Avocados be Z
Total cost of the Fruits = 19.5
So the equation would be as follows:
6x + 6y + 6z = 19.5
for Apples, equation would be:
6x= 19.5 - 6y - 6z
x = (19.5 - 6y - 6z) /6
For Oranges, the equation would be:
6y= 19.5 - 6x - 6z
y = (19.5 - 6x - 6z) /6
For Avocados, the equation would be:
6z= 19.5 - 6x - 6y
z = (19.5 - 6x - 6y) /6
Answer:
The midpoint is (1, 4.5)
Step-by-step explanation:
To find the midpoint, take the coordinates for the two endpoints and add the x's and divide by two. Then add the y's and divide by two. R has coordinates (-4,0) and B is (6,9). On this particular question when we just do half of the problem we can pick out the correct answer from the multiple choice list. -4 + 6 is 2. And divided by 2 is
2/2 is 1 there is only one choice that has an x that is 1. It doesn't hurt, nor take much time to confirm with the y's. 0+9 is 9. And 9/2 is 4.5.
So the midpoint is (1, 4.5)
