The fifth graders are planning a pizza party. each fifth grader will eat two slices of pizza with a favorite topping. each fifth grader selects a favorite topping. one-half of the students want pepperoni. one-fourth of the students want extra cheese. one-eighth of the students want sausage. four students want mushrooms. how many students select a favorite topping for their pizza slice.

There are 32 students that select a favorite topping.

Let x be the total number of students.
1/2 of the students, or 1/2x, choose pepperoni.
1/4 of the students, or 1/4x, choose cheese.
1/8 of the students, or 1/8x, choose sausage.
4 students choose mushrooms.

We know that if we add all of the students together we will get the total number of students, which we defined as x:

1/2x+1/4x+1/8x+4=x

We will use 8 as the common denominator of these fractions:
4/8x+2/8x+1/8x+4=x

Adding like terms,
7/8x+4 = x

Subtract 7/8x from both sides:
7/8x+4-7/8x = x-7/8x
4 = 1x-7/8x
4 = 1/8x

Divide both sides by 1/8:
4÷(1/8) = 1/8x÷(1/8)
4/1 ÷ 1/8 = x
4/1 × 8/1 = x
32/1 = x
32 = x

There are 32 students.

Letter c hope it

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
