Choose the missing step in the given solution to the inequality -x -10 > 14 + 2x <br>

Andreyy89

Answer:

x < -8

Step-by-step explanation:

-x - 10 > 14 + 2x

Subtract 2x from both sides;

-3x - 10 > 14

Add 10 to both sides;

-3x > 24

Divide both sides by -3

The sign switches when divide by a negative number.

x < -8

First, rewrite 17/25 and 13/20 so that they have a common denominator. Then, use to order 17/25 and 13/20

Elenna [48]

Please Help!! Urgent ( Zoom in to see it better)

1. You are trying to isolate "F" in the equation

$C=\frac{5}{9}(F-32)$ Multiply 9/5 on both sides

$(\frac{9}{5})C=(\frac{9}{5}) \frac{5}{9} (F-32)$

$\frac{9}{5}C=F-32$ Add 32 on both sides

$\frac{9}{5}C+32=F-32+32$

$\frac{9}{5}C+32=F$

THIS IS WRONG

2. You are trying to isolate "y" in the equation

$m=\frac{x+y+z}{3}$ Multiply 3 on both sides

3m = x + y + z Subtract x and z on both sides

3m - x - z = y

THIS IS CORRECT

3. Isolate "r"

$s=\frac{r}{r-1}$ Multiply (r - 1) on both sides

s(r - 1) = r Distribute s into (r - 1)

sr - s = r Subtract sr on both sides

-s = r - sr Factor out r from (r - sr)

-s = r(1 - s) Divide (1 - s) on both sides

$\frac{-s}{1-s}=r$

THIS IS WRONG

4. Isolate "b"

$A=\frac{1}{2}(a+b)$ Multiply 2 on both sides

2A = a + b Subtract a on both sides

2A - a = b

THIS IS CORRECT

5. Isolate "y"

$m=\frac{x+y}{2}$ Multiply 2 on both sides

2m = x + y Subtract x on both sides

2m - x = y

THIS IS WRONG

The 2nd and 4th one is right
