Answer: 36

--------------------------------------------------------------------------------

Explanation:

There are 35 girls and 50 boys. Making 35+50 = 85 students total.

Of the 85 students, 42% (see column 1, bottom row) bought their lunch from the cafeteria. So 0.42*85 = 35.7 which rounds to 36

Write an equation and solve: Your math homework has 6 more than three
lorasvet [3.4K]

Answer: 33 math problems.

Step-by-step explanation:

Let x = Number of math problems

y= Number of history problems

According to the question , we have

3y+6=x\ \ \ \ \ (i)\\\\ x+y=42\ \ \ \ (ii)

We can rewrite (i) as x-3y=6    (iii)

Now, subtract (iii) from (ii), we get

y-(-3y)=42-6\\\\\Rightarrow\ y+3y=36\\\\\Rightarrow\ 4y=36\\\\\Rightarrow\  y= \dfrac{36}{4}\\\\\Rightarrow\  y=9

Put this in (i), we get

x=3(9)+6 = 27+6=33

Hence, you have to complete 33 math problems.

Which of the following number lines represents the compound inequality shown below?
OLEGan [10]

Answer:

I'm not really sure what the question might be asking or if I've been given all the information but this is how you would solve it as (-2,4] meaning any real number between these will give you a real x on the domain.

Step-by-step explanation:

-4 < 3x + 2 \leqslant 14 \\  - 6 < 3x \leqslant 12 \\  - 2 < x \leqslant 4

You have purchased a property that you intend to rent out to people. The mortgage payment is $765/month and the property taxes a
Delicious77 [7]
Monthly mortgage payment multiplied by 12 months in a year. 
765*12=9,180.
Add yearly mortgage plus property taxes:
9,180+4,056=13,236
Divide the total by 12 months in a year. 
13,236/12=1,103
You should charge $1,103 a month to come out even. 

You can also take the property taxes and divide them by 12 (months in a year)  4056/12=338. Then add the monthly mortgage ($765) 
 765+338= $1,103.

Hope this helps :)
