There is a relationship between the number of hours a plumber works and the amount of money he earns. The plumber earns $60 for every 2 hours he works. Which statement about the relationship and the amount of money the plumber earns is true? Practice
A
The number of hours the plumber works is the independent variable in the relationship, and he earns $270 for 9 hours of work.

B
The amount of money the plumber earns is the dependent variable in the relationship, and he earns $540 for 9 hours of work.

C
The amount of money the plumber earns is the independent variable in the relationship, and he earns $540 for 9 hours of work.

D
The number of hours the plumber works is the dependent variable in the relationship, and he earns $270 for 9 hours of work.

Step-by-step explanation:

number of hours  worked 2 = money earned $60,

so we can conclude that

the money he earned depend on the hours worked (independent variable) and that

number of hours  worked 1 = money earned $30

A. True

hours worked IS the independent variable

9 hours of work = 9*$30  = $270 IS correct

B. False

money earned IS the dependent variable

9 hours of work is NOT $540

C. False

the money earned is NOT independent

for 9 hour will NOT earn $540

D.True

the number of hours IS dependent variable

the 9 hours of work IS earning $270

answer: 12

step-by-step explanation:

because yes

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
