Answer:
y=30
Step-by-step explanation:
this fits into the negative association if you plotted the point (80,30) it would fit into the graph and not stand out in either direction
(4x+7)/5 = 58
Cross Multiply:
4x+7 = 5*58
4x + 7 = 290
Subtract 7 from both sides:
4x = 283
Divide by 4 on each side:
x = 70.75
D) 70.75! :)

Answer:
44
Step-by-step explanation:
Lunch = 3 appetizers per guest
If there are 22 guests: 22 × 3 = 66 appetizers served
Dinner = 5 appetizers per guest
If there are 22 guests: 22 × 5 = 110 appetizers served
Difference = total dinner appetizers - total lunch appetizers
= 110 - 66
= 44
X=4 because when you square 4 you get 16! Aka 4x4=16. Also the other one is 16 divided by 4. Hope this helped
