Answer:
x = 14
y = 30
Step-by-step explanation:
x + 10 = 3x - 18
x = 3x - 18 - 10
x = 3x -28
x - 3x = -28
-2x = -28
x = 14
(3x - 18) + (6y - x - 10) = 180
3x - x -18 - 10 + 6y = 180
2x - 28 + 6y = 180
2x + 6y = 180 + 28
2(14) + 6y = 208
6y = 208 - 28
6y = 180
y = 30
I hope this helps!
If your meal costs $14 and you wish to leave a 20% tip, you can find the total amount to pay by mult. $14 by 1.20:
1.20($14) = $16.80. The tip would be $2.80.

Answer:
Step-by-step explanation:
#2 Should be many to one; the reason for this is when doing functions a proper one will have one input to one output.
#3 Should be D; same reasoning as above.
And sorry I am at a loss for #1.
Triangle WXZ and triangle XZY are similar triangles by the side angle side similarity postulate, therefore 16/12 = 12/9.
<h3>What are
similar triangles?</h3>
Two triangles are said to be similar if they have the same shape and the ratio of their corresponding sides are in the same proportion. Also, their corresponding angles are congruent.

For the scatter plot on homework:
a) The relationship is that the test score will increase, if the time spent on homework increases.
b) The function is y=8x+40, and what we need to see is what the score will be if someone puts in 3 hours of homework, x=3 in this because it means the time spent on homework:
y=8(3)+40
y=24+40
y=64
c) The score would be 40% if no time was spent doing homework.
For the scatter plot on the rides:
a) y = -7/5x + 17.8
b) Anika worked 17.8 hours on Day 0
c) Decreased by 7/5 in a day.
Hope this helps, have a BLESSED AND WONDERFUL DAY! As well as a great Superbowl Weekend! :-)
