Answer:
420
Step-by-step explanation:
Let x = number of $40 tickets.
Let y = number of $60 tickets.
x + y = 700
40x + 60y = 33600
-40x - 40y = -28000
20y = 5600
y = 280
x + y = 700
x + 280 = 700
x = 420
Answer: 420 $40 tickets were sold
Given the equation y= -3x+2.5, when y is 8.5, what value of x makes the equation true?
PLEASE EXPLAIN HOW YOU GOT YOUR ANSWER AS WELL !! ( im not very smart :c )
Answer:
x= -2
Step-by-step explanation:
First, write your equation with 8.5 substituted for y: 8.5= -3x +2.5
Next, subtract 2.5 from both sides to simplify the equation: 6= -3x
After that, divide both sides by -3 to get x by itself: -2 = x
So, when y=8.5, x=-2.

Correct Question
A dentist is making identical dental care bags for patients using 56 tubes of toothpaste, 112 packets of floss, and 84 toothbrushes. What is the greatest number of identical dental care bags the dentist can make with the least amount of items leftover? Describe the contents of each bag.
Answer:
What is the greatest number of identical dental care bags the dentist can make with the least amount of items leftover?
28 identical dental care bags
Describe the contents of each bag.
2 tubes of toothpaste, 4 packets of floss and 3 toothbrushes.
Step-by-step explanation:
We solve for this using greatest common factor method
Step 1
Find the factors of 56, 84 and 112
The factors of 56 are: 1, 2, 4, 7, 8, 14, 28, 56
The factors of 84 are: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84
The factors of 112 are: 1, 2, 4, 7, 8, 14, 16, 28, 56, 112
The greatest common factor amongst them is = 28
Hence, the greatest number of identical dental care bags the dentist can make with the least amount of items leftover is 28 bags.
Describe the contents of each bag.
Each bag should contain 2 tubes of toothpaste, 4 packets of floss and 3 toothbrushes.

if p varies inversely as the square root of q, and p=12 when q=36, find p when q=16
Answer:
Step-by-step explanation:
p = k / sqrt(q)
The first job is to find k.
p = 12
q = 36
Solution for k
12 = k / sqrt(36)
sqrt(36) = +/- 6
Multiply both sides by +/-6
12 * +/- 6 = k
k = +/- 72
Solution for q = 16
p = +/-72/ sqrt(16)
p = +/- 72 / sqrt(16)
p = +/- 72 / +/-4
p = 18

Lauren's net pay after deductions will be equal to $623.52
What will be the net pay of Lauren?The net pay of the Lauren will be calculated as
The gross pay is = $ 765
The Federal tax = $68
Social security tax on gross pay 6.2%= [tex]SST=765\times 0.062=47.43[/tex]
Medicare tax on gross pay 1.45%= [tex]765\times 0.0145=11.09[/tex]
State tax on federal tax holdings 22% =[tex]68\times 0.22=14.96[/tex]
Now the net pay will be
[tex]=765-68-47.43-11.09-14.96=623.52[/tex]
Thus Lauren's net pay after deductions will be equal to $623.52

For his phone service, Hong pays a monthly fee of $30, and he pays an additional $0.07 per minute of use. The least he has been charged in a month is $124.92.
What are the possible numbers of minutes he has used his phone in a month?
Use m for the number of minutes, and solve your inequality for m.
Answer:
First, let's set up the equation
· We know the least total he's got in one month is $124.92
· In that one month, he was charged an additional $30 dollar fee.
· During the time he uses his phone, he is charged $0.07 per unknown minutes (which we can consider 'm').
It would look like this;
30 + 0.07m = 124.92
where $30 is the additional fee
$0.07 is the money he is charged per unknown minutes otherwise known as 'm'
$124.92 is the total of that whole month (which has been the least amount of money he used)
So now we solve for m:
30 + 0.07m = 124.92
-30 -30(get rid of any constants first by performing the inverse operation of addition, subtraction)
0.07m = 94.92
/0.07 /0.07 (isolate 'm' by applying the inverse operation of multiplication, division)
m = 1,356 minutes

Given ∆ADB and ∆ACB. These triangles can be proven congruent by ASA, if two additional statements are provided.
Answer: First option
Step-by-step explanation:
Mr. M traveled 5 miles fewer than twice the number of miles on Tuesday as Monday. On Wednesday he traveled 40 more than the square of the number of miles traveled Monday. If the total miles traveled was 1,024, write an equation to represent the total miles traveled on Monday, Tuesday and Wednesday.
Answer:
x² + 3x - 989 = 0 (where x is the number of miles traveled on Monday)
Step-by-step explanation:
Let x = number of miles traveled on Monday
Let y = number of miles traveled on Tuesday
Let z = number of miles traveled on Wednesday
Given:
Mr. M traveled 5 miles fewer than twice the number of miles on Tuesday as Monday⇒ y = 2x - 5
Given:
On Wednesday he traveled 40 more than the square of the number of miles traveled Monday⇒ z = x² + 40
Given:
Total miles traveled = 1024⇒ x + y + z = 1024
Substitute y = 2x - 5 and z = x² + 40 into x + y + z = 1024:
⇒ x + 2x - 5 + x² + 40 = 1024
⇒ x² + 3x + 35 = 1024
⇒ x² + 3x - 989 = 0 (where x is the number of miles traveled on Monday)

A bank offers a savings account that earns 0.5% interest each month.
Write an equation for the balance of the savings account after Y months.
Given an initial deposit of 500$ what will the account balance be after 15 months.
Answer
Step-by-step explanation:
This is exponential growth, so we would use the following equation
y=a(b)^x
500(1.005)^15
1. Initial amount is $500, since that's what we started with.
2. Add the following percentage by 100%
100%+0.5%= 1.005
3. We need to find the account balance after 15 months so raise it to the 15th power.
y= 500(1.005)^15
The balance after 15 months will be $538.84.

Step-by-step explanation:
Given the following question:
[tex]12(s-10)[/tex]
To rewrite the expression using the distributive property we have to remember the rule that applies to all expressions, we have to multiply all the terms inside the paratheses by the terms outside of the paratheses.
[tex]12(s-10)[/tex]
[tex]12\timess=12s[/tex]
[tex]12s-10\times12[/tex]

[tex]12s-120[/tex]
Your answer is "12s - 120."

One brand of juice contains 0.05 of natural juice. Which is this decimal written as a percent?
A) 0.05%
B) 5%
C) 0.5%
D) 50%
Answer:
B.) 5%
Step-by-step explanation:
You'll need to multiply 0.05 by 100. Since 100 = 1, we are only multiplying by 1 and not changing the value of our number.
0.05 × 100 = 5
5/100 is 5 over 100 and means 5 per 100. 5 "per 100" means 5 "percent" or 5%
Therefore, 0.05 = 5%
