Using the together rate, it is found that they would prepare the solution in 1.71 minutes working together.
<h3>What is the together rate?</h3>
It is the sum of each separate rate.
In this problem, the rates are given by:
Hence the together rate is given by:
7x = 12
x = 12/7
x = 1.71.
They would prepare the solution in 1.71 minutes working together.

Answer:
Yor answers would be :
For the 5th pic :
The equation of the line : Y= -2X + 4
Y-intercept : 4
The slope : -2
For the 7th pic :
The equation of the line : Y=4/3X-4
Y-Intercept : -4
The slope : 4/3
I don’t know the gap at the beginning but the answer is c
The answer is 4. 2x plus 7 is equal to 15. First you subtract 7 from both sides then divide by 2 to get the answer 4. Hope this helps!
To find out a glass prism's surface are you should first find the, base's are. Since the base is triangle, it's are formula is :
(which h is height and b is base length).
since there are two triangle's their total area will be 70.2 To find the remaining surface's are multiply the perimeter of the base with the length.
then sum the total surface : 70,2 + 2025 = 2095,2
