Answer:
x = 3 and y = 1
Step-by-step explanation:
Given equations
y=3x-8 and y=4-x
We will substitute y from second equation in the first and get:
4-x = 3x-8 first we will add (+x) to both sides and get
4-x+x = 3x+x-8 => 4 = 4x-8 now we will add (+8) to the both sides and get
4+8 = 4x-8+8 => 12 = 4x now we will change the sides of equation and get
4x = 12 => x = 12/4 = 3 => x=3 now we will replace x=3 in the second equation
y= 4-x = 4-3=1 => y=1
Finally we have (x , y) = ( 3 , 1)
God with you!!!
This is quite easy. you have 5 as a whole, think, 1 whole is 3/3 so 3/3/ 5 times is 12, add another 3 to that for 15 then add one to 15, BOOM! you have 16 batches of cookies.

Answer:
1. Proportional
2. Not proportional
3. Not proportional
Step-by-step explanation:
Let's see what percentage of the $8.80 order is the $1.32 tip.
To find what percent a p[art is of a whole, divide the part by the whole and multiply by 100%.
$1.32/$8.80 * 100% = 15%
Mike's tip was $15% of the total.
1. $2.22 tip on $14.80 order
15% of $14.80 = 0.15 * $14.80 = $2.22
Tip is proportional
2. $1.86 tip on $10.50 order
15% of $10.50 = 0.15 * $10.50 = $1.58
Tip is nor proportional
3. Same as option 2 above.
