Joy added 26 new contacts to her phone list. She now has a total of 100 contacts. Let c represent how many contacts joy had on her phone before she updated it
Answer:
c=74
Step-by-step explanation:
Let c represent how many contacts Joy had on her phone before she updated it.
Because Joy added 26 new contacts, we can say that c+26 is equal to her new total of 100 contacts.
c+26=100
Therefore, the equation that represents this situation is c+26=100
Now, we can use our equation to solve for c.
c+26=100
Subtract both sides by 26 to isolate c
c+26-26=100-26
c=74
Therefore, Joy had 74 contacts on her phone before she updated it.

Answer:
x=-14 is the answer. Hope this helps :)
Answer:
x=-14
Step-by-step explanation:
(x/2)-(3x/4) = (-x/4) = 7/2
-x =14 (multiply by 4)
x = -14 (multiply by -1)

Answer:
m = 1/2
Step-by-step explanation:
To find the slope, all you have to do is find the rise and divide it by the run. Rise means how many units you move up or down from point to point. Run means how far left or right you move from point to point.
You can pick any two points on the line. Let's say I choose (10, 5) and (20, 10).
Let's look at the y coordinates first. You have 5 and 10. To get from 5 to 10, you have to go up 5 units. Your rise is 5. Let's look at the x coordinates now. To get from 10 to 20, you have to go up 10 units. Your run is 10.
As I said before, the slope is rise/run. In this case, we have 5/10, which can be simplified to 1/2. Your slope is 1/2.
Note that any two points on this would give you the same answer of 1/2 for this line. If I had picked (30, 15) and (70, 35), I would still get 1/2.
Hope this helped!

Assume you know that a hot-air balloon is currently inflated with a certain amount of air and that the amount is a percent of the total amount required to inflate the balloon. Explain how you would determine the total amount of air required to inflate the balloon.
Answer:
Percent air is calculated as:
Percent air = Current amount/Total amount *100Solve for total amount of air:
Total amount = Current amount / Percent air * 100Substitute the values in hand to get the answer

Answer:
The answer is 5
Step-by-step explanation:
Write the product 3i(5 - 3i) in the form a + bi.
An imaginary number is denoted by i.
The value of i is √-1.
Imaginary number.
i= √-1
i² = -1
i³ = -i = -√-1
The product of 3i (5 - 3i) in the form of a + bi is
9 + 15i.
What is an imaginary number?An imaginary number is denoted by i.
The value of i is √-1.
We have,
Imaginary number.
i= √-1
i² = -1
i³ = -i = -√-1
Now,
3i (5 - 3i)
Removing the parenthesis.
= (3i x 5) - (3i x 3i)
= 15i - 9(-1)
= 15i + 9
= 9 + 15i
This is in the form of a + bi
Thus,
The product of 3i (5 - 3i) in the form of a + bi is
9 + 15i.

Answer:
Probability = [tex]\frac{22}{31}[/tex]
Step-by-step explanation:
Number of students working part time, living in dorm = 22
Total number of students working part (either living in dorm or not in dorm)
= 22 + 9
= 31
Probability of the students working part time and living in dorm,
P = [tex]\frac{\text{Favorable event}}{\text{Total outcomes}}[/tex] = [tex]\frac{\text{Students working part time either living in dorm}}{\text{Total number of students working part time either living in dorm or not}}[/tex]
P = [tex]\frac{22}{31}[/tex]
Therefore, probability of the students chosen that he/she is working part time given that he/she lives in dorm is [tex]\frac{22}{31}[/tex].

At a park, the cost to rent a bike has an initial fee of $15.00 plus $7.50 per hour. Which equation models the relationship between total cost, y, and the number of hours, x, that the bike is rented?
Answer:
y = 15 + 7.50x
Step-by-step explanation:
It is given that, At a park, the cost to rent a bike has an initial fee of $15.00 plus $7.50 per hour.
Let the number of hours is x and the total cost is y.
When the bike is rented for x hours, its cost will be 7.50x.
Total cost (y) in terms of number of hours is given by :
y = 15 + 7.50x
Hence, this is the required equation.
how do you solve 4devided by
12
Answer:
0.33333333
Step-by-step explanation:
4 divided by 12 would be written like this: 4/12
it's always good to simplify if possible, so it should look like this: 1/3
3 which is the denominator would be divided by 10, so 3/10 = 0.33333333
0.33333333 is the answer because the numerator is how many times you multiply it, and 1*0.33333333 = 0.33333333

A pie shop sold a total of 208 pies one day. The pies were apple, cherry, and blueberry. The ratio
of apple pies sold to cherry pies sold to blueberry pies sold was 6:4:3. How many of each type
were sold?
Plss step by steppp
Answer:
96 apple pies, 64 cherry pies, and 48 blueberry pies.
Step-by-step explanation:
6 + 4 + 3 = 13, and 208 / 13 = 16. Now multiply each number in the ratio by 16, so 6 x 16 = 96, 4 x 16 = 64, and 3 x 16 = 48. You can check your answer by adding all 3 numbers and making sure it adds up to 208. Hope that helps

do you guys mind helping me with this question
Answer:
4 and 6
Step-by-step explanation:
Judging by the table and how x = 1 and y = 2, you can estimate that y is twice as much as x.
This is supported by the equation, if you take 2 and multiply it by x (1) and take 3 and multiply it by y (2), then add the 2x1 (2) and 3x2 (6), you should get 8.

Answer:
2. Definition of supplementary angles
3. [tex]\angle 1 + \angle 2 = \angle 1 + \angle 3[/tex]
4. [tex]\angle 2 = \angle 3[/tex]
5. Definition of congruent angles
Step-by-step explanation:
Required
Fill in the gaps
1. Given
Supplementary angles: [tex]\angle 1[/tex] and [tex]\angle 2[/tex]
Supplementary angles: [tex]\angle 1[/tex] and [tex]\angle 3[/tex]
2. Supplementary angles add up to 180.
So:
[tex]\angle 1 + \angle 2 = 180[/tex]
[tex]\angle 1 + \angle 3 = 180[/tex]
3. Apply transitive property on (2)
[tex]\angle 1 + \angle 2 = 180[/tex] and [tex]\angle 1 + \angle 3 = 180[/tex], then
[tex]\angle 1 + \angle 2 = \angle 1 + \angle 3[/tex]
4. Subtract [tex]\angle 1[/tex] from both sides
[tex]\angle 1 - \angle 1 + \angle 2 = \angle 1 + \angle 3 - \angle 1[/tex]
[tex]\angle 1 - \angle 1 + \angle 2 = \angle 1 - \angle 1+ \angle 3[/tex]
[tex]\angle 2 = \angle 3[/tex]
This property is called the subtraction property
5. If [tex]\angle 2 = \angle 3[/tex],
Then [tex]\angle 2[/tex] and [tex]\angle 3[/tex] are congruent
