Answer:

Margaret has 2 flowers

Step-by-step explanation:

First we can make a set of equations

j = 3m

a = 3j

a + j + m = 26

Since j = 3m we can rewrite Anna's equation as a = (3(3m)) or simply a = 9m

Now we can plug in the equations for Anna and Jessica into the main equation

9m + 3m + m = 26

13m = 26

m = 2

Sharonda uses a blend of dark chocolate and milk chocolate to make the ice cream topping at her restaurant. She needs to buy 120
White raven [17]

Step-by-step explanation:

ATQ,

Let d be the number of kilograms of dark chocolate she buys and m be the number of kilograms of milk chocolate she buys.

She needs to buy 120 kg of chocolate in total for her next order, and her recipe calls for twice the amount of dark chocolate as milk chocolate.

So,

m = 2d .....(1)

m + d = 120 ...(2)

We can also solve the above equations,

Put m = 2d in equation (2)

2d + d = 120

3d=120

d = 40

Put d = 40 in equation (1)

m = 2(40)

m = 80

Hence, she will need 40 kg of dark chocolate and 80 kg of milk chocolate.

How do I find the median for 77,82,87,85,32,78?
alisha [4.7K]

Answer:

80

Step-by-step explanation:

The median is the middle value of the data arranged in ascending order. If there is no exact middle then the median is the average of the 2 values either side of the middle

Arrange the data in ascending order ( smallest to largest )

32, 77, 78, 82, 85, 87

There is no value exactly in the middle, use the average

median = \frac{78+82}{2} = \frac{160}{2} = 80
