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

The height of a triangle is twice its base. If its area is 121cm^2 Find its base​
kozerog [31]

Answer:

The base is 11 cm.

Step-by-step explanation:

The formula for the area of a triangle is A = \frac{1}{2} bh. If we plug in what we know to this equation, we are left with 121 = \frac{1}{2} * b * 2b, which we now need to simplify.

First, we combine like terms.

121 = \frac{1}{2} * 2b^{2}

Then, we can eliminate the \frac{1}{2} and 2 on the right side of the equation, since they cancel each other out.

121 = b^{2}

Finally, we take the square root of both sides of the equation and find our answer:

11 = b
