Answer:

Step-by-step explanation:

so the first bit you don't even need its trying to trick you

first you do 72/6= 12 so that means for every 12 students, you need one tutor

then you do 120-72=48 and that means there are 48 students that have no tutor

to find out how much more tutors you need, do 48÷12= 4, meaning you need 4 extra tutors for the 48 more kids.

last you add 72 witch is the about of tutors you started with, to 4 witch is how much you just got.

72+4=76

What is 24.051 rounded to the nearest hundredth? How did you solve it?

4vir4ik [10]

This is like late elementary/early middle school stuff where you learn this.
First off, what number is in the position of the hundereth place? 0? No. 1? No. 5 yes! Now how i learned how to round is you take the number to the right of whatever you are being asked about and round it up or down. Now if the number (in this case it is 1) is lower than 5, you round down (or keep it the same) but if it is 5 or higher you round up. since 1 is lower then 5, that 5 in the hundereths place stays the same.

skad [1K]

Answer:

$\boxed{\bold{ab+9a-6}}$

Step-by-step explanation:

Remove parenthesis: (a) = a

$\bold{2ab+9a-4-\left(ab+2\right)}$

$\bold{-\left(ab+2\right): \ -ab-2}$

$\bold{2ab+9a-4-ab-2}$

Simplify $\bold{2ab+9a-4-ab-2}$

$\bold{ab+9a-6}$

Help me plz idk how to do this :)

Anna35 [415]

Hey there :)

Without using a calculator it is not hard to identify where it lies.
√88

Which are the perfect squares before and after √88 ?
√81 which is 9 and √100 which is 10

Therefore, √88 is between 9 and 10

In case you use a calculator, we can see that:
√88 = 9.38

9 < 9.38 < 10

$\boxed {Your \ answer \ will \ be \ 9 \ and \ 10}$
