5 Select the correct expressions. Which expressions are equivalent to 3x + 2(x - 1) - 4? 3x + 2x - 2 - 4 5x - 6 3(x-4) 3(x + 2)

beks73 [17]

Your question is a bit unclear, but I will try to answer it anyway.

The expression 3x + 2(x - 1) - 4 simplified is:

3x + 2(x - 1) - 4

= 3x + 2x - 2 - 4

= 5x - 6

I cannot tell what the answers are but I am guessing they are these?:

A) 3x + 2x - 2 - 4

B) 5x - 6

C) 3(x - 4)

D) 3(x + 2) - 6

E) 6(x - 1)

Answer A is one, and so is answer B. If I read your question accurately.

I hope I helped!

There are 58 students enrolled in an art class. The day before the class begins, 10.3% of the students cancel. How many students

Sidana [21]

First, set up a proportion. 10.3% is the percentage of students who cancelled, but the question is asking for the students who are attending, so let’s use 89.7% to make it easier. The proportion would be x over 58 is equal to 89.7% over 100%. Multiply 58 by 89.7, giving you 5,202.6. Next, take 5,202.6 and divide it by 100. This should give you 52. 026, but it’s best to round this to 52. 52 students actually attend the art class, making this your final answer.

dangina [55]

the height of the tree is 23 feet .

<u>Step-by-step explanation:</u>

Here we have , Tony is 5.75 feet tall. Late one afternoon, his shadow was 8 feet long. At the same time, the shadow of a nearby tree was 32 feet long. We need to find Find the height of the tree. Let's find out:

According to question , Tony is 5.75 feet tall. Late one afternoon, his shadow was 8 feet long . Let the angle made between Tony height and his shadow be x . Now , At the same time, the shadow of a nearby tree was 32 feet long. Since the tree is nearby so tree will subtend equal angle of x. Let height of tree be y , So

⇒ $Tanx=\frac{y}{32}$
