Step-by-step explanation:

-9<4x+3≤27 |-3 (because we have to remove everything what's next to the x)

-9-3<4x+3-3≤27-3

-12<4x≤24 |:4

-12:4<4x:4≤24:4

-3<x≤6

x = (-3;6]

Emerson struck out 112 times in 350 at-bats. What is the percent of strike outs per at-bat?

Natasha2012 [34]

We are told that Emerson struck out 112 times in 350 at-bats. We are asked to find the percent of strike outs per at-bat.

Let us find out 112 is what percent of 350.

$\text{Percentage of strike outs per at-bat}=\frac{112}{350} \cdot 100$

$\text{Percentage of strike outs per at-bat}=0.32 \cdot 100$

$\text{Percentage of strike outs per at-bat}=32$

Therefore, Emerson struck out 32% of the at-bats.

Solve 2(4 x + 3) < 5 x + 21. { x | x < 9} { x | x > -5} { x | x > -9} { x | x < 5}

Nesterboy [21]

Answer:

x <5

Step-by-step explanation:

2(4 x + 3) < 5 x + 21

Distribute

8x +6 < 5x +21

Subtract 5x from each side

8x -5x +6 < 5x-5x+21

3x +6 < 21

Subtract 6 from each side

3x+6-6 <21-6

3x <15

Divide each side by 3

3x/3 <15/3

x <5
