Mathematics
2 answers:
Artemon [7]3 years ago

Answer:

7/24

Step-by-step explanation:

-1/3+-5/8 = -1/3-5/8

find the LCD which is 24 so we mutiply -1/3 by 8 on both sides to get the 24 on the bottom so it'll be -8/24. Then we multiply -5/8 by 3 to get the same denominator so itll be -15/24. so (-8-(-15))/24 can also be re written as (-8+15)/24. so 15-8 (will give you the same answer) is 7 so its 7/24 and you can not simplify that fraction so that is the answer

Answer:

The solution to the given inequality

 h\geq \frac{-1}{21}

Step-by-step explanation:

Given inequality

                      \frac{-1}{3h} \leq 7

             ⇒     -1≤ 7× 3h

             ⇒     -1 ≤ 21 h

             ⇒    21 h ≥ -1

            ⇒       h\geq \frac{-1}{21}

Three boys share R2100 in ratio 3:5:7 calculate how much each boy will get​
aleksandrvk [35]

The amount each boy receives from the R2100 is R420, R700 and R980 respectively

<h3>How to find ratio</h3>

Total amount = R2100

Ratio = 3 : 5 : 7

Total ratio = 3 + 5 + 7

= 15

First boy = 3/15 × 2100

= 0.2 × 2100

= R420

Second boy = 5/15 × 2100

= 0.33333333333333 × 2100

= R700

Third boy = 7/15 × 2100

= 0.46666666666666 × 2100

= R980

What is the approximate solution to this equation?
Nookie1986 [14]

Answer:

  C.  x ≈ 0.28

Step-by-step explanation:

A graphing calculator solution is attached. It shows ...

  x ≈ 0.28

__

You can divide both sides of the given equation by 5, then take natural logs and divide by 5 again.

  5e^(5x) = 20 . . . . . . given

  e^(5x) = 4 . . . . . . . . divide by 5

  5x = ln(4) . . . . . . . . take natural logs

  x = ln(4)/5 . . . . . . . divide by 5

  x ≈ 0.277259 ≈ 0.28
