Which expression is equivalent to 4x+3x+4-2x

Mathematics
1 answer:
kvv77 [185]3 years ago
6 0

Answer:

5x+ 4

Step-by-step explanation:

First, put all of the x variables together. So 3x+4x=7x

7x + 4 -2x  Since the 2x is negative you can subtract it from 7x and get 5x.

you can not add the four to the 5x because it does not have a matching variable.

So, you have: 5x+ 4

d = 60 miles * 4 hours
d = 240 miles.

Dave loves underwater diving. His house boat is 250 feet above sea level. He jumped from that level. He went 600 feet below sea
nikklg [1K]

Answer:

<h3>600 feet</h3>

Step-by-step explanation:

<u>I would just like to explain how this works with a visual (please enjoy my drawing <3 haha)</u>

With my drawing we know that the bird is 150 feet above sea level, and the fish is 100 feet below sea level.

From the bird to the water it is 150 feet, from water to fish is 100 feet

<u>From</u><u> the </u><u>bird</u><u> to the</u><u> fish</u><u> it is </u><u>150 feet + 100 feet</u>

<h3>This is equal to 250 feet, </h3>

so we know from the bird (150 feet above sea level) to the fish(100 feet below sea level).

<h2>Knowing this information we can easily answer this question</h2><h3>Dave is 250 feet above sea level, and he went 600 feet nelow sea level, meaning<u> he only went 600 feet under the water.</u></h3>
