The length of a red string is 7 less than 8 times the length of a yellow string.

Find the length of the red string when the length of the yellow string is 5.

Solution:

Let length of red string = a

Let length of the yellow string = b

Given that,

length of the yellow string is 5

b = 5

The length of a red string is 7 less than 8 times the length of a yellow string

Therefore,

a = 8b - 7

Substitute b = 5

a = 8(5) - 7

a = 40 - 7

a = 33

Thus length of red string is 33

the correct answer is b) histograms can be used to exhibit the shape of distributions. this is because histograms count the frequency of each possible answer, so one is able to see which results are more common and which are less common.

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
