HELPP. Write the following as an algebraic expression. The sum of a and a quarter of b.
Fynjy0 [20]

Answer: a + \frac{1}{4}b

This is the same as a + \frac{b}{4}

All we're doing is adding 'a' and \frac{1}{4}b since the term "sum" is the result of adding two or more numbers.

One quarter of a number is the same as dividing by 4.

Example: one quarter of 28 = \frac{1}{4}*28 = \frac{28}{4} = 7

N-2=10n+4 over 2 what is the value of n
Snowcat [4.5K]

Consider the given equation:

n-2 = \frac{10n+4}{2}

Cross multiplying in the given equation, we get

(n-2) \times 2 = 10n+4

Applying distributive property which states a(b+c) = ab+ac, we get

(n \times 2) - (2 \times 2) = 10n+4

2n -4 = 10n+4

Adding '4' on both the sides, we get

2n-4+4 = 10n+4+4

2n = 10n+8

Subtracting '10n' from both the sides of the equation, we get

2n-10n = 10n+8-10n

-8n = 8

Dividing by '-8' in both the sides of the equation, we get

n= -1

Therefore, the value of 'n' is -1.
