Investment = $5,000

Annual Interest = 5%

5000/100 x 5/1

Answer:

C) x = 1

Step-by-step explanation:

By adding the like terms you get

-12x + 10 = -10x + 8

then you add 12x to both sides and subtract 8 to both sides and get

2 = 2x

which then you would divide 2 by 2 and get 1

Which expressions are monomials?

Nimfa-mama [501]

Monomials are the expressions with one terms.

A.) $-4+6 = 2$

Since, it has only one term. Therefore, it is a monomial.

B.) $b+2b+2 = 3b+2$

Since, it has two terms. Therefore, it is not a monomial.

C.) $(x-2x)^2 = (-x)^2=x^2$

Since, it has only one term. Therefore, it is a monomial.

D.) $\frac{rs}{2}$

Since, it has only one term. Therefore, it is a monomial.

E.) $36x^2yz^3$

Since, it has only one term. Therefore, it is a monomial.

F.) $a^x$

Since, the variable is in the power. So it is not a monomial.

G.) $x^\frac{1}{3}$

Since, the power is not a integer. Therefore, it is not a monomial.
