Answer:
Sorry if this isnt helpful: Im just going off stuff i learned to see if this will help you at all. Im only in 7th so.. Sorry in advance!!
Step-by-step explanation:
To find the rate, you need to create a unit rate table thing, like this:
5/3 = ?/1 To do this, you would need to divide 5 by 3 and 3 by 3 to get y and x. You get: 1.666 continued. Rounded, about 1.7 . so your unit rate for part A is 1.7/1. You would do the same thing. 2/3 = ?/1. I will let you solve that :)))
Finished A! Now B:
To compare, we use the butterfly method! so 1.7/1 o ?1. cross multiply, and whichever number is bigger comes on top. Then you would explain why that number is bigger. BAM
Answer:
3x + 20 = 80
Step-by-step explanation:
If Sam gets paid $20 a week whether she makes any cakes or not, that is a fixed amount. The amount that she makes will only go up IF she makes cakes. She makes $3 per cake she bakes, and if the number of cakes is our unknown, the expression for that is 3x. Adding that to the fixed amount she makes is 3x + 20. Now we set that equal to 80, which is what she made in a week and solve it for x, which gives us the number of cakes she had to bake to make that $80.
3x + 20 = 80
Answer:
Owen can afford to keep and drive the car for 4 days.
Step-by-step explanation:
The total owing on the car rental is R(d) = ($77.25/day)d + ($0.12/mile)m ≤ $330. Substitute 1 for d (that is, the rental is for 1 day) and 175 for m:
R(d) = ($77.25/day)(d days) + ($0.12/mile)(175 miles) ≤ $330
= $77.25d + $21 ≤ $330
This simplifies to $77.25d + $21 ≤ $330, or
$77.25d ≤ $309
Solving this by dividing both sides of the above equation by $77.25, we get
d = ($309)/($77.25) = 4
Owen can afford to keep and drive the car for 4 days.
6y + 5 > 8
6y> 8-5
6y> 3
y>3/6
Thus, y>1/2
