If four times a number plus 3 is 11, what is the number? a. 4 bm 2 c. 16 d. 5

goblinko [34]

Answer:

B. 2 (Second Option)

Step-by-step explanation:

Four times: ⇒ 4

Number:⇒ y

4y+3=11

Subtract by 3 both sides of equation.

4y+3-3=11-3

Simplify.

11-3=8

4y=8

Divide by 4 both sides of equation.

4y/4=8/4

SImplify, to find the answer.

8/4=2

y=2 is the correct answer.

2 is the correct answer.

Answer:

x=3.89

Step-by-step explanation:

I'll go in depth for you.

Before we figure out what we do, let understand what we know about this triangle.

We know that both triangles have a angle that measure 27°.
We also know EH=5
FG=9
ZG=7
We need to know how to find EZ

Notice how line EG and HF intersect at Angle Z. We know that if two lines intersect at an angle, it form angles called vertical angles. This means that the two angles that are vertical to each other are congruent.

This means that angle Z in both triangles both measure the same.

Now since both triangles have 2 congruent corresponding angles, we can say that the Triangles are Similar due to the Angle-Angle Postulate.

"If two corresponding angles of two triangles are congruent, then the two triangles are similar."

What is mean when Triangles are similar? 

It means that the similar triangles corresponding angles are equal and their sides are in proportion.

The corresponding sides are 

EH and GF

EZ and ZG

HZ and HF.

Our proportion formula for similar triangles is 

Any two sides of the first triangle divided by each other must equal the two corresponding sides of the second triangles divided by each other respectively.
