Answer:
<em>See the graph with both lines attached</em>
A) From the tables we see the constant change of values in the second column and the initial value is zero.
This represents a proportional relationship for both tables.
B) <u>Revel</u>
- Rate of change is 5 per hour, the equation is:
- y = 5x, where y is cost, x - is the number of hours
<u>Scooters</u>
- Rate of change is 6 per hour, the equation is:
- y = 6x, where y is cost, x - is the number of hours
C) <u>When x = 12</u>,
- y = 5*12 = $60 for Revel
- y = 6*12 = $72 for Scooters
D) <u>The point (4, 24) represents that:</u>
- The cost of 4 hours is $24
E) The second table has confusing titles (days and number of cell phones) but if we assume its same as the first table, then Revel has lower rate as 5 < 6.
Comparing the prices and the graph, Revel has better rate per hour.
Answer:
the answer is 15
Step-by-step explanation:
i actually did the test :D
2/6 * 24 = 8 council members vote for a new park
so they need to convince 13-8 = 5 more members
Step-by-step explanation:
let w be the cost of a bottle of water and p be the cost of a bag of pretzels
"2 bottles of water and 3 bags of pretzels is $7.05" can be written as
2w + 3p = 7.05 ------------- eq.1
"The cost of a bag of pretzels is $1.35" can be written as
p = 1.35 ------------- eq 2
Together, eq 1 and eq 2 make up your system of equations
To solve, take eq 2 and substitute this value int eq 1
2w + 3 (1.35) = 7.05
2w + 4.05 = 7.05
2w = 7.05 - 4.05
2w = 3
w = 1.5
Hence the cost of a bottle of water is $1.50
Answer:
49
Step-by-step explanation:
Since we are rounding to the nearest whole number we look at the tenth decimal place (the 1)
Since a one is less than 5 we keep the number the same. If it was over 5 we would round the whole number up to a 50. I hope this makes sense! Have a nice day :D
