I think the answer is half of one number to the other
Answer:
Step-by-step explanation:
-7+-3= -10 6+9=15
-10/2=-5 15/2=7.5
Step-by-step explanation:
I think the answer is x=-4,x=+6
now, le'ts do the summation using 0.5n+2
(0.5(2.7) + 2)+(0.5(3.0) + 2)+(0.5(3.2) + 2)+(0.5(3.7) + 2)+(0.5(4.4) + 2)+(0.5(4.9) + 2)+(0.5(5.3) + 2)
which gives us 27.6. Now, the paper doesn't state, or at least I don't see it, but that's just the sum of the hours, to get the average we simply divide that by 7, the amount of items, and 27.6 ÷ 7 gives us about 3.94.
does it underestimate or overestimate the one found with the summation? well, the summation gave us 3.9 and 3.94 is just 0.04 or 4 hundredths above it.
Answer:
c = ½(p + 2s)
Step-by-step explanation:
Let c = the total cost
p = cost of one shirt
2s = cost of two sweaters
p + 2s = total cost before discount
But Alana paid only half the regular price, so
c = ½(p + 2s)
