Hey! So the the answer to your question is 77.

This is because to find out how many grapefruits they sold, you would first need to find the two numbers to you can multiple 10 and 1 by so they would add up to 307 and 100. The numbers that work are 23 and 77. So, when you multiply 10 to 23 (10 because it’s the cost of nuts), you would get the answer of 230. Then you would subtract 307 by 230 because 307 is the total amount of money they earned from selling. When you do that, you would get 77. After that, you multiply 1 times 77 because the cost of the grapefruit is $1. When you add 23 and 77, you should get 100. The total items they sold. When you add 230 and 77, youd get 307. So, there were 77 grapefruits that they sold.

Hopefully this is right

I believe x = 12

Step-by-step explanation:

If the triangles were similar then they would have the same angle measures.

Steps:

Add angle K and L: 90 + 54 = 144

Subtract the added angles from 180 to find angle J: 180 - 144 = 36

Angle J is similar to angle X so, divide 36 by 3: 36/3 = 12

x = 12

11.6 km²

Step-by-step explanation:

Divided it into two shapes, a triangle and a rectangle. Then find the area for each. The triangle is 4 km long and 2.2 km wide. The rectangle is 1.8 km wide and 4 km long.Solve the area for the triangle. The equation l · w ÷ 2=A will help. So, the equation would be 4 · 2.2 ÷ 2=4.4Then, solve the area for the rectangle by using the equation l · w=A. 1.8 · 4=7.2Add them together. 4.4+7.2=11.6Final answer - 11.6 km²

Which is NOT a line of symmetry (please help)

Answers

Answer:

3

Step-by-step explanation:

The line 3 is not a line of symmetry.

What is Line of Symmetry?

Line of symmetry of a figure or a shape is the line which divides the figure or shape in to equal and symmetrical parts.

This line is also called as axis of symmetry.

It is sometimes also called as mirror line since the line divides in to parts which looks like mirror images.

Given is a shape of a triangle.

There are 4 lines drawn.

Of these, 3 lines are drawn from a vertex of the triangle to the middle point of the opposite side, which divides the triangle in to two equal triangles.

So these lines are lines of symmetry.

But line 3 does not divide the triangle in to equal parts.

So it is not line of symmetry.

Hence line 3 is not a line of symmetry.
