Try using a scratch piece of paper to graph the points of each table to see which one would have a negative slope. Or use the formula y1-y2/x2-x1 to find the slope and see which one is negative.
Answer: Sally paid less
Step-by-step explanation:
From the question, Sally paid $1.50 for 2 1/2 pounds of apples at the Grocery Mart. The cost per pound of apple will be:
= $1.50 ÷ 2 1/2
= $1.50 / 2.5
= $0.6 pee pound of apple
Fred paid $1.95 for 3 pounds of apples at the Corner Fruit Stand. The cost per pound of apple will be:
= $1.95 / 3
= $0.65 pee pound of apple.

Answer:
10k-4=2k-20
+4 +4
10k=2k-16
-2k -2k
8k=-16
k=-2
Check:
10(-2)-4=2(-2)-20
-20-4=-4-20
-24=-24
Step-by-step explanation:
651.2 is the answer if you add and subtract yhe numbers twice
You would use PEMDAS so that means you would start by multiplying 3 with the parentheses 3(2+6d) on both sides then you would combine like terms so you would add 18d+18d. Then you would subtract 6- -5 on both sides then solve for a one-step equation
3(2+6d)-5=3(2+6d)-5
6+18d-5=6+18d-5
6+36d-5=6-5
1+36d=1
-1. -1
36d/36. 0/30
D=0
