I’m not 100% sure but my best guess would be
6.A
7.A
8.C
9.C
10.D
so john is x and if Maya has the same as john but -3 then
x+x-3
but sam is still missing and she has half of Maya which is 0.5x - 1.5
so the equation is
x+x-3+0.5x-1.5=68
and then you add 3 and 1.5 to 68 which is
2.5x=72.5
and you divide by 2.5 which is 29
John has 29 points
The answer is 0.87. Hope i could help
Answer:
a) 56.25 mph
b) $1.59/lb
Step-by-step explanation:
The units of the "unit rate" tell you the math operation you need to perform.
<h3>a)</h3>
Miles per hour (mi/h) is found by dividing miles by hours.
(450 mi)/(8 h) = (450/8) mi/h = 56.25 mi/h
<h3>b)</h3>
Dollars per pound ($/pound) is found by dividing dollars by pounds.
($7.95)/(5 pounds) = (7.95/5) $/pound = 1.59 $/pound
__
<em>Additional comment</em>
In the context of unit rates, "per" means "divided by."
What makes a rate a "unit rate" is the "1 unit" in the denominator. For miles per hour, the denominator is 1 hour. For dollars per pound, the denominator is 1 pound.
