Answer:
4.5
Step-by-step explanation:
7.3= y + 2.8
Subtract 2.8 from both sides
7.3 = y+ 2.8
-2.8 -2.8
--------------------
y = 4.5
Answer:
False
Step-by-step explanation:
y = -3× - 2
4 = -3(2) - 2
4 = -6 - 2
4 = -8
Answer:
Shania has read the most pages.
Step-by-step explanation:
Following the formula y = mx + b.
Kevin already read 45 pages.
y = mx + 45
He reads 20 pages per hour, since it has per hour, we put it has "m"
y = 20x + 45
Shania already read 5 pages
y = mx + 5
Shania reads 25 pages per hour
y = 25x + 5
We need to find out how many pages they read after 20 hours, plug 20 into x.
Kevin
20(20) + 45 =
400 + 45 =
445
Shania
25(20) + 5 =
500 + 5 =
505
Shania read 60 more pages than Kevin.
Answer:
1. $8.30
Step-by-step explanation:
so 3 hats were purchased and each cost 15.50 so
15.50*3=46.50
and the rest of the 96.30 is 6 keychains so
96.30-46.50=49.80
and there is 6 keychains
49.80/6=8.30
Each key chain was $8.30
Claire's answer is unreasonable because when we got the price of the keychains all together in Claire's mind the total for the keychains would be $4.98, which we clearly got the total for the keychains at $49.80.
