72 cookies per 36 minutes = 72/36
If both values are divided by 36:
2/1, or 2 cookies per (one) minute.
<span>Brainiest would be nice.</span>
1:1, because there’s a same number of both !
Answer:
First mechanic worked for 10 hours and second mechanic worked for 15 hours.
Step-by-step explanation:
Let first mechanic worked for X hours and second mechanic worked for Y hours .
Now, according to the question , they worked for a total of 25 hours .
Thus ,
X + Y = 25.
Y = 25 - X -(1)
Also, first mechanic is charging $ 95 per hour and second mechanic is charging $115 per hour .
Thus, total money charged by them will be 95X + 115Y .
Which is given to be $2675 in the question.
Thus 95X + 115Y = 2675. -(2)
Putting equation 1 in equation 2 we get ,
95X + 2875 - 115X = 2675
20X = 200
X = 10 hours.
Thus , Y = 25 - X = 15 hours.
Thus first mechanic worked for 10 hours and second mechanic worked for 15 hours.

Answer as follow: happy to help always.....
Step-by-step explanation:
x-3.5 = 7.2
x = 7.2+ 3.5
as you know that 3.5 is subtracting over other side while moving it on 7.2 side it will add..
7.2+3.5
10.7
so,
x= 10.7
you can check ✅✅✅✅
Thank you!!!!!!!!!
