Answer:
your answer is 6 hours
Step-by-step explanation:
you have the 2nd pipe takes 72 hours so then you multiply 4 x 9 x 12 which is 432 and then you divide 432 by 72 which is 6 so it would be 6 hours
hope it helps ^^
Answer:
A system of linear equations contains two or more equations to solve a problem. We graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect.
Step-by-step explanation:
Answer:CD = x = 4 units
Explanation:We are given that the two triangles are similar. This means that we can set the similarity proportionality as follows:
![\frac{BC}{CD} = \frac{CA}{CE} = \frac{AB}{ED}](https://tex.z-dn.net/?f=%20%5Cfrac%7BBC%7D%7BCD%7D%20%3D%20%20%5Cfrac%7BCA%7D%7BCE%7D%20%3D%20%20%5Cfrac%7BAB%7D%7BED%7D%20%20%20)
W e have:
BC = 20 - x
AC = 20
CD = x
CE = 5
Substitute in the above proportionality and solve for x as follows:
![\frac{20-x}{x} = \frac{20}{5} = 4](https://tex.z-dn.net/?f=%20%5Cfrac%7B20-x%7D%7Bx%7D%20%3D%20%20%5Cfrac%7B20%7D%7B5%7D%20%3D%204)
4x = 20 - x
5x = 20
x = 4
Based on he above:
CD = 4 units
BC = 20 - x = 20 - 4 = 16 units

Answer: 7(5+6)
Step-by-step explanation:
The greatest common factor is the largest number that can both be divisible by 35 and 42
The distributive property is where a number is distributed to both numerals in the equation
Plug in 83 for y and 3 for x
83 = 3^2 - 6 (3) + 92
83 = 9 - 18 + 92
83 = -9 + 92
83 = 83 so it works
