Answer:

0 >n>-\frac{7}{2}

Step-by-step explanation:

2n+13-13>6-13

2n>-7

\frac{2n}{2}>\frac{-7}{2}

n>-\frac{7}{2}

n is negative, so it must be less than zero, 0 >n>-\frac{7}{2}

3(x+2)-2(×+1) i need help with this problem
zhuklara [117]

Question:

What is 3(x + 2) - 2(x + 1)?

Steps:

When you solve this type of equation always use the distributive property formula to solve this equation!

Formula: a(b + c) = ab + ac

So, what is 3(x + 2) ?

  • 3x + 6

Also, what is -2(x + 1)?

  • -2x - 2

Then, put it back into the equation for you to solve this problem.

So, this would be the new equation:

3x + 6 - 2x - 2

Then, what you want to do is put variables next to each other and the numbers next to each other so it will be easier to simplify:

3x - 2x + 6 - 2

Then, simplify:

x + 4 is the answer!

Since 3x - 2x = x and 6 - 2 = 4


Hope that helped!!

Can someone please please help me?? :(
salantis [7]

Answer:

-60 3/4m

Step-by-step explanation:

The diver first dives down 50 1/4m, which is represented by the -50 1/4m. He then descends another 10 1/2m down. So -50 1/4m - 10 1/2m.

-50-10=-60

-(1/4)-(1/2)= (1/4)+(1/2)

(1/4+1/2)=(2/8+4/8) you can only add with the same denominators.

=6/8 (simplifies down to 3/4)
