Answer:
12 minutes.
Step-by-step explanation:
Marla uses two copiers to make copies of a one-page newsletter. *Copier R makes 60 copies per minute. *Copier T makes 40 copies per minute.
Since both copier start at the same time, let the number of minutes used by both copiers be represented by x
60 × x + 40 × x = 1200 copies
60x + 40x = 1200
100x = 1200
x = 1200/100
x = 12 minutes
Therefore, it will take 12 minutes l to make 1200 copies.
Answer:
60 degrees and pi/3 radians
Step-by-step explanation:
A full revolution is 360° or 2pi
… so multiply by 1/6 to get 60° and pi/3 radians
It would take 125 loaves at a cost of $200 for the breadmaker and store bought bread to cost the same.
<h3>
Linear equation</h3>
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change and b is the y intercept.
Let x represent the rate of cost of one loaf and y represent the total cost, hence:
y = 0.8x + 100
The rate of cost of one loaf is $0.8 and the start up cost is $100.
For the second bread it is given by:
y = 1.6x
The graph of the two equations cross at (125, 200)
It would take 125 loaves at a cost of $200 for the breadmaker and store bought bread to cost the same.

The 5-d process is the process in answering problems with things meaning
if you have amanda is x and jake is 3 times amandas age....and there mother is 4 times jakes age..and there sum of ages is ....its these kind of problems. so you have a step by step process to solve them...(but you can do it without and skip a few steps when doing it )
but here it is-->
1) describle or draw the problem
2) Define (define what varables you are using
3) Do (Set up equation and solve)
4)Decide (chekc ur answer)
5)Declare ( write the final answer (ex..amanda is 2, Jake is 6...)
hope this helps
