Answer:

The correct option is C. The solution of given system of equations is (5,1).

Step-by-step explanation:

The given equations are

x+y=6           .... (1)

x-y=4           .... (2)

Add equation (1) and (2), to eliminate y.

2x=10

Divide both sides by 2.

x=5

The value of x is 5. Put this value in equation (1).

5+y=6

Subtract 5 from both the sides.

y=6-5

y=1

The value of y is 1. The point (5,1) is the solution of the given system of equations.

Therefore the correct option is C.

What is minimal completion time for the activities in the graph below? In a complete sentence, explain how you got your answer
kupik [55]
The minimal completion time for the activities is the shortest possible time for all the activities to be finished. In doing this, we look at the path that would require the greatest amount of time. At the START node, we choose the path that would take the longest which is 7 days leading to ACTIVITY D. Next, we choose the path leading to ACTIVITY B which takes 5 days. Then, we move to ACTIVITY C taking 5 days and finally, reach the END which would take 6 days. So, the minimal completion time is:
7 + 5 + 5 + 6 = 23 days

225 g flour
Pachacha [2.7K]
If she needs to use 225g of flour for each cake and wants to make 18 cakes she will need 4050g (225x18=4050) of flour but she only has 360g which is obviously not enough flour. For one cake she needs 75g of sugar and since she needs to make 18 cakes she needs 1350g (75x18=1350) of sugar. She only has 135g so it’s not enough.
