Answer:
3 hours
Step-by-step explanation:
t = time to make a table
c = time to make a chair
t + c = 5
t+3c = 9
Subtract the second equation from the first
t+3c = 9
-(t + c = 5)
-----------------------
2c = 4
Divide by 2
2c/2 = 4/2
c =2
2 hours for the chair
t+c = 5
t+2 = 5
t = 5-2
t = 3hours

Answer:
4. option A ---> m = 65h
Step-by-step explanation:
According to the question it states that,
- m --> number of miles traveled.
- h --> <u>over</u> hours
Now if we look at the table we need to find the starting point, or in other words, how much distance traveled in 0 hours. So we would divide miles / hours.
*Four hours, the variable in the question and in the table says n, but the answer choices says h, so I am saying h for hours just if you were wondering on it.*
distance (m) / hours (h)
130 / 2 = 65
195 / 3 = 65
325 / 5 = 65
455 / 7 = 65
So, our starting point, or numbers of miles traveled in 0 hours was 65. Now let us form an equation.
m = 65h
I would appreciate if you give me the brainlist or not. Hope this helps and stay safe, happy, an healthy, thank you :) !!
Area of a circle using the radius is pi*r^2, so:
A=3.14*4^2
A=3.14*16
A=50.24
