Answer:
Step-by-step explanation:
A fixed pulley consists of a wheel fixed to a shaft and is used in conjunction with a belt to transfer energy to another fixed pulley. A movable pulley consists of a shell, a movable wheel and a rope. Movable pulleys are also know as block and tackle.
Set equal to eachother
(2x+1) = 79
Subtract 1 from both sides
2x=78
Divide 2 from both sides
2x/2=78/2
X= 39
one term is monomial
two terms are binomials
three terms are trinomials
each term is separated by a + or - sign
so......6 has only one term ......it is a monomial
