An expressions equated to another expression is called an equation
An equation is an expression that is used to show the relationship between two or more variables and numbers.
Given that a = 5, hence:
2a + 5
substituting values:
2(5) + 5 = 10 + 5 = 15
2a + 5 = 15
The sum of twice and four times of the variable x is 2x + 4x = 6x

Answer
1. f - 3/4
2. 62 + h
Step-by-step explanation:
1. 1/4 of the fish are angelfish, all fish are one whole, one whole - 3/4's = 1/4
2. we dont have the value of H so we in turn have to figure out the equation and 62 + h is the only answer we can come to
56 divided by 40 is 1.4. Multiply that by 100 and you get 140.
This is the long way of doing it, but it's the way I've always done it.
Answer:
7.8 × 10-5 meters
Step-by-step explanation:
the length of the a human hair= 8.4 x 10^-5
length of the vicuna hair:0.000006 = 0.6 x 10^-5
===========================================
difference between human hair and vicuna hair:
8.4 x 10^-5 - 0.6 x 10^-5 = 10^-5 ( 8.4 - 0.6)
= 10^-5 (7.8)
= 7.8 x 10 ^-5 meters
