Olivia download music for $1.89 per song. She has a credit on her account for $3. Which expression could be used to represent the cost of the music if Olivia downloads m songs?
Answer:
Answer 3 (1.89m - 3)
Step-by-step explanation:
Since we know that the price per song is $1.89, that is going to be the part of the equation that goes with the variable.
Since she has a 3 dollar credit, this will reduce the cost of whatever amount of songs she is buying by 3 dollars, which means the second part of the equation is -3. You have your answer, 1.89m - 3.

Find the probability that the next student will select hamburger for lunch. You must write your answer as a fraction.
Answer: 12/40
Step-by-step explanation:
Basically you gotta add up all of the number of students who are getting each of the food, then you have to put the number of student that want a hamburger. You also have to create the fraction which is 12/40
Step-by-step explanation:
Total = 8 + 12 + 14 + 6 = 40
The amount of people who had a hamburger is = 12

9 orange + 10 purple = 19 total
First draw - get orange:
9/19
Second draw - get purple - without replacing:

During testing, the experimental probability of completing a new game with a perfect score was found to be StartFraction 1 over 500 EndFraction. If 1,000,000 people buy and play the game when it is released, how many players will complete the game with a perfect score?
Given: 1/500 and 1,000,000
Multiply 1/500 & 1,000,000
1/500 * 1,000,000 = 2000
Thus, 2000 people are likely to complete the game with a perfect score

Ellie is interested in getting a new phone. One phone company, phone 1 charges a monthly fee of 6$. They also charge 0.10$ per minute. Another company, phone 2, charges 5$ for a monthly fee and 0.25$ per minute. Write an equation for the total cost of each phone bill, where y is the total cost and x is the total number of minutes on the phone. Which company will allow Ellie to talk the longest is she only wants to spend 22$ a month
Answer:
Phone 1 will allow Ellie to talk the longest
Step-by-step explanation:
Phone 1:
(0.10x) + 6 = y
(0.10x) + 6 - 6 = 22 - 6
0.10/0.10x = 16/0.10
x = 160 minutes
Phone 2:
(0.25x) + 5 = y
(0.25x) + 5 - 5 = 22 - 5
0.25/0.25x = 17/0.25
x = 68 minutes

The difference of the two numbers is 1.Their sum is 23.find the numbers
Answer:
11 and 12
Step-by-step explanation:
The two numbers will be called x and y. The sum of x and y is 23 and the difference is 1.
x + y = 23
x - y = 1
Add the equations together
x + y + x - y = 23 + 1
2x = 24
x = 12
y = x - 1
y = 11

James adds vitamin drops to his fish tank to keep his fish healthy. If James
follows the instructions on the bottle of vitamins, how many capfuls should he add
to his 450-litre tank? (4 marks)
• 2 drops per 5 litres
of water
• 1 capful = 40 drops
Step-by-step explanation:
350/5=70 liters X 2 drops for every 5 liters=140 drops needed for the whole tank.
Since 1 cupful contains 40 drops, the we have this:
140 drops needed for the full tank/40 drops contained in one cup, or,
140/40=3 1/2=3.5 number of cupfuls needed for the full tank.
hopefully this helps

Answer:
x = 60°
Step-by-step explanation:
This is a congruent triangle, and the extension is parallel to one side, also making it 60°. All congruent triangles are equilateral.
Hope this helps! :-)
Answer:
a) x = 60°
b) since it is an equilateral triangle, all 3 inside corner angles = 60°.
since the 2 horizontal lines are parallel, x = the same side interior angle of 60°
