First plugin 2y+4 for x
3(2y+4)+5y=32 distribute
6y+12+5y=32 combined like terms
11y+12=32 combined like terms
11y=20 divide
Y=1.818
V = length x width
5 x 8 = 40
3 x 4 = 12
40 + 12 = 52 (answer for #3)
4 x 6 = 24
14 - 6 = 8
8 x 9 = 72
24 + 72 = 96 (answer for #4)
7 x 6 = 42
3+6+3 = 12
5 x 12 = 60
60 + 42 = 102 (answer for #5)
Answer:
Step-by-step explanation:
x + 8 = -2
x = -10
the answer is a
Let r = usual driving rate
let t = usual driving time
We need to figure out t
The distance she covers in her usual time at her usual rate is r*t
The distance she covers in her new time at her new rate is:
(1+t)*((2/3)r)
Set this equal to each other and solve for t.
rt = (2/3)r + (2/3)rt
(1/3)rt = (2/3)r
(1/3)t = (2/3)
t = 2
So her usual time is 2 hours. (There's probably a faster way to do this)
Answer:
2 friends have more than 5 cards
Step-by-step explanation:
Incomplete question;
I will answer this question with the attached dot plot
The horizontal axis represents the friends, the vertical represents the number of baseball trading cards and the dots represent the frequency
So, we have:
The friends that has more than 5 are:
<em>Hence, 2 friends have more than 5 cards</em>
