A mobile phone carrier charges an extra fee if a customer uses more than 500 minutes each month. Tom has already used 230 minutes this month. Which inequality can be used to determine how many more minutes Tom can use this month without going over the 500-minute limit?
A. 230 + m > 500
B. 230 + m greater-than-or-equal-to 500
C. 230 + m < 500
D. 230 + m less-than-or-equal-to 500
Answer:
230 + m < 500
Step-by-step explanation:
The inequality shows that the combined total of 230 and m (stands for minutes Tom can use) is less than 500.
To win the recycling contest, you must collect a total average between 83 and 87 pop tabs for 4 weeks, inclusive. Suppose you collected 82, 86, and 84 pop tabs during the first three weeks of competition. What are the possible number of pop tabs you can collect during the last week in order to win the recycling contest?
Write an inequality where X is the number of pop tabs you can collect during the last week. Then solve to find out the possible number of pop tabs you can collect.
Answer:
Inequality:
83 ≤ (82 + 86 + 84 + x)/4 ≤ 87
Step-by-step explanation:
You must collect no less than 80 and no more than 96 pop tabs.
8. Felicity bought 34 of a pound
of hamburger. She used 12 of the
hamburger for dinner. How much
hamburger did she use?
9514 1404 393
Answer:
3/8 pound
Step-by-step explanation:
If Felicity started with 3/4 pound and used 1/2 of it, then the amount she used was ...
(1/2)(3/4 pound) = (1·3)/(2·4) pound = 3/8 pound
Felicity used 3/8 pound of hamburger for dinner.
The measures of 13 of the 14 angles of a 14−gon add up to 2,016°. What must the fourteenth angle measure be?
Answer:
[tex]x = 155 \frac{1}{13}[/tex] or 155 1/3 degrees. If you want a decimal, 155.076923 degrees.
Step-by-step explanation:
2,016 is the sum of 13 identical numbers. Let's say the unknown number is [tex]x[/tex]. We'll now write an equation to solve it.
[tex]13x = 2016[/tex]
Divide both sides by 13.
[tex]x = \frac{2016}{13}[/tex]
Now, I went ahead and solved this and ended up with a repeating decimal. But for your sake we'll just make it a nice mixed number.
13 goes into 2016 155 times.
Here, I'll check for you.
[tex]13 * 155 = 2015[/tex]
So, if we were to turn this into a mixed number, we'd get something like this.
[tex]x = 155 \frac{1}{13}[/tex]
That should be your fourteenth angle measure.

KL = 23
so you just have to add both of the segment lengths together.
each individual equation is already given in the image, so I'll substitute it out below:
JK + KL = JL
4x+2 +4x+3 = 45
8x + 5 = 45
8x = 40
x = 5
BUT WE'RE NOT DONE. plug in 40 for the variable X:
KL = 4(5) + 3
KL = 20 + 3
KL = 23
now i'll check my answer really quickly:
23 + 4(5) + 2 = JL
23 + 20 + 2 = JL
23 + 22 =
45
therefore, KL is 23

A tennis pro has 12 can of tennis balls. There are 3 balls in each can. He gives an equal number of balls to each of the 4 players. After the lesson, he realizes that each player lost 3 balls. How many tennis balls are left? Show your work and explain (in complete sentences) how you found your answer.
Answer:
24 Tennis balls
Step-by-step explanation:
Calculation for How many tennis balls are left
First step
Since we have 12 can with 3 balls each Let the number of balls that the tennis pro has at the beginning be x
x=(12 can ×3 balls each)
x=36
Second step
Since we have 4 players who lost 3 ball each Let the total number of balls that was lost be y
y=(4 players×3 balls each)
y=12
Third step is to calculate How many tennis balls are left
Since x represent the number of balls at the beginning and y represent the number of balls that was lost , then let the number of tennis balls that was left after the session represent z
z=36−12
z=24 Tennis balls
Therefore the numbers of tennis balls that are left will be 24 Tennis balls

Nick and June win some money and share it in the ratio 3:1. Nick gets 30 £60 more than June. How much did they get altogether
Answer:
£120
Step-by-step explanation:
With regards to the above, the difference between the ratio is
3:1 is 2
I.e
(3 - 1) = 2
Nick gets 2 extra, which is equal to £60
Therefore,
1 share = £60/2 = £30
June gets 1 share = 1 × £30 = £30
Nick would get = 3 × £30 = £90
Therefore, the value gotten by both would be;
= £30 + £90
= £120

Answer:
The equation is;
y = 1/2x + 7
Step-by-step explanation:
Here, we want to write in the slope-intercept form, the equation that goes through the two points
The general form of this is;
y = mx + b
where m is slope and b is the y-intercept
we start by calculating the slope of the line
m = (y2-y1)/(x2-x1)
m = (8-6)/(2-(-2))
m = 2/4 = 1/2
So we have ;
y = 1/2x + b
To get b, we use any of the two pints
8 = 1/2(2) + b
8 = 1 + b
b = 8-1
b = 7

~Please I really need help~ Alex works as a carpenter making wooden tables. He is guaranteed a base pay of
$300 per week, and also earns $50 per completed table. Write an equation to
determine Alex's weekly pay. He hopes to make at least $800 per week. How many
tables per week does he need to make?
Answer:
Alex needs to make 10 tables per week.
Step-by-step explanation:
If his base pay is $300, then subtract it from $800, you get $500. Then divide $500 by how much Alex earns per table, $50, then you get 10. Alex needs to make 10 tables per week.
In January, Dawn earns $9.25 allowance. She earns 3 times as much in February. If during March, she earns $5.75 more than she did in February, how much allowance does she earn in March?
Answer:
$33.50
Step-by-step explanation:
$9.25 is how much she has in January and she earns 3 times as much in February. So multiply 9.25 and 3, then you get 27.75. We need to find out how much she makes in March so simply add $27.75 and $5.75.
Your answer will be $33.50
