Answer:
the two points represent solutions to the equation 3x - 9y= 18
if y = 0,
3x - 9(0) = 18
3x = 18
x = 6
(6,0): point 1
if x = 9
3(9) - 9y = 18
27 - 9y = 18
-9y = -9
y = 1
(9, 1) : point 2
Step-by-step explanation:
Answer: x=3-2y/3
Step-by-step explanation:
You just have to try to isolate one variable
If you let the width be x, then the length will be 2x + 3. The perimeter P is
twice the width plus twice the length, i.e.,
P = 2*x + 2*(2x + 3) = 2x + 4x + 6 = 6x + 6.
So if the perimeter is 66 cm then 66 = 6x + 6 ---> 6x = 60 ---> x = 10 cm.,
and so if the perimeter is at most 66 cm., the width can be at most 10 cm..
The state sales tax in Colorado is 2.9%.
We know that because we divide 2.32/80. We have to find out what percent the tax is of the amount paid. The answer comes to 0.029. Multiply it by 100, and you get 2.9%
Answer: 2x -5
Step-by-step explanation:
Hi, to answer this question we have to write equations with the information given:
- <em>John has × marbles </em>
John=x
- <em>Max has twice (multiplied by 2) as many.max give gives john 5 of his marbles.
</em>
We have to multiply by 2 the number of marbles that John has (x), and subtract 5.
Max = 2x -5
