What is the solution to the linear equation?<br>2/5 + p = 4/5 + 3/5p​
N76 [4]

Answer:

<h2>p = 1</h2>

Step-by-step explanation:

\frac{2}{5}  + p =  \frac{4}{5}  +  \frac{3}{5} p

Multiply through by the LCM

The LCM for the equation is 5

That's

5 \times  \frac{2}{5}  + 5p = 5 \times  \frac{4}{5}  +  \frac{3}{5}p  \times 5

We have

2 + 5p = 4 + 3p

Group like terms

5p - 3p = 4 - 2

2p = 2

Divide both sides by 2

We have the final answer as

<h3>p = 1</h3>

Hope this helps you

Which is a correct first step in solving 5 – 2x &lt; 8x – 3?
marusya05 [52]
When approaching an equation such as this, it is important to consider the acronym PEMDAS, which stands for parenthesis, exponents, multiplication, division, addition and subtraction. According to these rules, as there are no numbers in brackets, the first thing you need to do is to add the exponent 2 to 8x.

Joe was walking to a grocery store at a speed of 50 feet in 9 seconds. at what speed was he walking in miles per hour
sashaice [31]

Answer:

3.79 miles per hour to the nearest hundredth.

Step-by-step explanation:

There are 3600 seconds in 1 hour.

50  feet in 9 seconds = 50/9 feet per second.

= (50/9) * 3600  feet  per hour

= (50/9) * 3600 / 5280 miles per hour.

= 50 * 400 / 5280

= 3.79 miles / hour.
