Math..plzz anyone who is good at this stuff...?

Question

Okay here are 5 questions if you could help me i will be VERY thankful! Or at least explain how you got the answer.

I have to SIMPLIFY all these questions.

This is question number 1:

Number 1: 15x6 divided by 3

Number 2: -7 x (-6)divided by(-3)

Number 3: -2(-9) divided by 6

Number 4: 5x(-2)x(-3)+7

Number 5: 10-(-4)x(+2)





THANKS!

Answer 1

1. 15 x 6 divided by 3
15 x 6 = 90
90/3 = 30

2. -7 x -6 divided by -3
-7 x -6 = 42
42 / -3 = -14

3. -2 x -9 divided by 6
-2 x -9 = 18
18/6 = 3

4. 5 x (-2) x (-3) + 7
5 x -2 = -10
-10 x -3 = 30
30 + 7 = 37

5. 10-(-4) x 2
-4 x 2 = -8
10-(-8)=18

here's the rules-
you have to do order of operations
so you do the multiplication and division first and which ever one comes first in the problem is the one you do first
and when you have a number minus a negative number
like the 10-(-4)
it's the same as saying
10 + 4
but in that problem, you have to first multiply the 2 and -4

if you have any questions about how i did that, message me

Answer 2

Number 1: 15x6 divided by 3 15*6/3=30

Number 2: -7 x (-6)divided by(-3) -7*(-6)/(-3)=-14

Number 3: -2(-9) divided by 6 -2*(-9)/6=3

Number 4: 5x(-2)x(-3)+7 5*(-2)*(-3)+7=30+7=37

Number 5: 10-(-4)x(+2) 10-(-4)*2=10+8=18

Answer 3

We got turded answerers here. But I'm nice enough to help you.

1. 15*6/3. Ok, now, find 15*6 (90) and divide it by three.
Simplified, it's 90/3, but the answer is 30.
2. (-7)(-6)/(-3). Find -7*-6 (42) then divide by -3.
Simplified, it's 42/-3, but the answer is -14.
3. -2(-9)/6. Find -2*-9 (18), then divide by six.
Simplified, it's 18/6, but the answer is 3.
4. 5(-2)(-3)+7. Ok, now for some hard stuff!
Mulitply first (5*-2*-3=30), then add seven.
Simplified, it's 30+7, but the answer is 37.
5. 10-(-4)(2). Mulitply first (-4*2=-8), then subtract from ten.
Simplified, it's 10-(-8), but the answer is 18.

Kelly, I'm great with math so drop me an IM or email anytime!

Answer 4

(1)15 * 6 / 3 = 90/3 = 30
(2) 7 * -6 / -3 = -42 / -3 = 14
(3) -2 * -9 / 6 = 18 / 6 = 3
(4) (5 * -2 * -3) + 7 = 30 + 7 = 37
(5) 10- (-4 * 2) = 10 + 8 =18 (this is the right)
or if u mean (10 - (-4)) * 2 = 14 * 2 = 28

Answer 5

# 1 15 can be divided by 3 so instead 15x6/3 you can simplify as 5x6 (15/3=5) same for remaining questions find which number can in the niminator can be divided by deniminator

Answer 6

1.90 divided by 3= 30
2.-42 divided by-3=14
3.18 divided by 6= 3

Answer 7

1. 15X6/3
=30
2. -7X-6/-3
=-14
3.-2(-9)/6
=3
4. 5X-2X-3+7
=37
5. 10-(-4)X2
=18

Answer 8

Look, I know the answeres to all these questions. I know how to do them. But for your own benefit, do your own schoolwork becuase in higher grades or university, you won't be able to get anwers off the internet. Also, some people could accidently give you the wrong answer and if you use this answer, YOUR answer will be wrong.
I wish I could do them for you, but I'm doing the right thing and this is on your behalf.

Answer 9

15*6/3 = 30

-7*(-6)/-3 = -14

-2*(-9)/6 = 3

5*(-2)*(-3)+7 = 37

Answer 10

Ask your parents for help with this homework and your Math teacher on Monday. If you have this for homework then you should know how to figure them out girl...
