Which is the correct first step in solving the inequality -4(2x-1)>5-3x algebraically?

1 answer:

3 0

The correct first step is to distribute the -4 into 2x - 1. This will result in -8x + 4 > 5 - 3x. Now, the next step is to solve for the equation. This results in:
-5x + 4 > 5
-5x > 1
x < -0.2
Hope this helps!

jolli1 [7]

Step-by-step explanation:

Given that,

Amy jogs 1/3 of a mile in 1/15 of an hour and john takes 1/30 of an hour to jog 1/5 of a mile.

Speed of Amy,

$v_1=\dfrac{\dfrac{1}{3}\ miles }{\dfrac{1}{15}\ h}=5\ mph$

Speed of John,

$v_2=\dfrac{\dfrac{1}{5}\ miles }{\dfrac{1}{30}\ h}=6\ mph$

John will jog farther in one hour as he is moving with faster speed. The speed of John is 1 mph more than Amy.

to find the median you arrange the values from the lowest to highest value, then you find the MIDDLE number.. if theres two in the middle add them and divide by two.
