It would be -40,20 and -10,-20
Answer:
x = 3
Step-by-step explanation:

I'm going to use the method of elimination by multiplying the second equation by -3:

Then I can eliminate x:
-32y = -64
To solve for y, I'd simply divide:
y = 2
Because I now have y = 2, I'll just plug in 2:
6x - 5(2) = 8
6x - 10 = 8
6x = 18
x = 3
Hopefully I helped :)
The total number of cups for younger kids is 3.66 and for the older kids its 7.5 so if you add those together it is about 11.16 which is less than 12 cups, so your answer is yes she does have enough
Answer:
<u>y = -3x - 0.25</u>
Step-by-step explanation:
Write the equation of a line that has a slope of -3 and passes through the point (1.25, -4).
We'll use the point-slope form of y = mx + b, where m is the slope and b the y-intercept (the value of y when x = 0).
We are told the slope, m, is -3.
y = -3x + b
We need to find a value for b that will cause the line to go through point (1.25,-4), We can do that by entering this point in the equation we have this far:
y = -3x + b
-4 = -3(1.25) + b
-4 = -3.75 + b
-0.25 = b
<u>The equation is: y = -3x - 0.25</u>

Answer:
r= -6
Step-by-step explanation:
first we move the terms
6r-7r = 13-7
-r= 6
and once we change the signs
r= -6
