Answer:
![7.5](https://tex.z-dn.net/?f=7.5)
Step-by-step explanation:
We already have our equation, which is 0.80s = 6.00
This means that in this problem, we must find what the s variable is.
All you really have to do is divide 6.00 by .80.
![6 / 0.80 = 7.5](https://tex.z-dn.net/?f=6%20%2F%200.80%20%3D%207.5)
0.80(7.5) = 6.00
Now to interpret the solution, Maxine can afford spending 7.5 (or 6) songs to download by only using 6 dollars.
Take any 2 points and find the slope of the line connecting them:
<span>1 9
3 8
9-8 1
slope m is m = ------- = -------- = -1/2

Answer:
Table 1
Step-by-step explanation:
To determine if it is proportional, y/x must be constant
Table 1
y/x = .5/1 = 1/2
1/2 =
3.5/7 = 1/2
4/8 = 1/2
This is constant
Table 2
y/x = 1/3
2.5/ 7.5 = 1/3
4/15 = 2/5 so it is not constant
Table 3
y/x = 12/3 =4
15/6 =5/2 not constant
Table 4
y/x = 7/2
9/3 = 3 not constant
Answer:
B
Step-by-step explanation:
Since x is 2 wherever you see x put 2
solve x3 + x7+ 2
=(2)3 + (2)7 + 2
= you do the number outside the bracket multiplied by the number inside the bracket
like this
=(2 × 3) + (2 × 7) + 2
= 6+ 14 + 2
= 22
Answer:
c and d
Step-by-step explanation:
in the bar diagram it shows that 2a's + 45 = 195 and so any of the equations that are equal will be the answer which is c and d
