A student plans to build a birdhouse and has a document that lists each step for building it. Which question is the student most likely to ask before she reads the document?

b). What materials will I need?

Explanation:

As per the situation provided, the most probable question that the student must ask before reading the document would be 'what materials he would require.' This is because the document describes the procedural information regarding the process of making a birdhouse in the form of steps, one after another, and in order to follow the process, the student must possess the required materials. This question will help him gather all the materials required that will be required to build it. Hence, option b is the correct answer.

x=4, y=4

step-by-step explanation:

y=2x-4;

x+2y=12

we can use substitution since the first equation is solved for y

where ever you see y in the second equation, replace it with 2x-4

x + 2(2x-4) = 12

distribute the 2

x+4x-8 = 12

combine like terms

5x-8=12

add 8 to each side

5x-8+8=12+8

5x=20

divide by 5

5x/5 = 20/5

x =4

we still need to solve for y

y = 2x-4

we know x =4

y = 2(4) -4

y = 8-4

y=4
