Trever and Marisa together have 28 t shirts to sell if marissa has 4 fewer t shirts than trevor find how many t shirt Trevor has
Salsk061 [2.6K]

Answer:

   Trevor has 16 number of shirts

Step-by-step explanation:

We have been given that Trevor and Marisa together have 28 t shirts to sell if Marissa has 4 fewer t shirts than Trevor

let the number of shirts Trevor have be x

And since, Marissa has 4 fewer than Trevor so number of shirts Marissa will have be x-4

Hence, according to question equation becomes:

x+x-4=28

We will solve for x to find the number of t shirts  Trevor has

2x -4 =28

2x = 32

x =16

Hence, Trevor has 16 number of shirts

Mekhanik [1.2K]

Answer:

A) A = 1; B = 0; C = 20

Step-by-step explanation:

The standard form for a quadratic is

Ax^2 +Bx +C=0

We are given

1/4x^2 + 5 = 0

Rewriting

1/4x^2 +0x+ 5 = 0

A = 1/4  B=0 C=5

We can multiply each side by 4

4(1/4x^2 +0x+ 5) = 0*4

x^2 +0x+ 20 = 0

A = 1  B=0 C=20
