The math club wants to order t-shirts to recognize students who improved their performances in algebra I. Hot shirt charges $10 per shirt with a $15 set up fee. T-shirt world charges $5 per shirt with a $50 set up fee charged. for what number of shirts is the cost of ordering t-shirts the same at both stores?
what does that cost?
let x equal the number of t-shirts
let y equal the cost of the shirts altogether
For the following problem, apply all six steps of the
process for solving systems of equations problems.
a. Define the variables (check)
b. Write a system of equations to model the situation.
c. Solve the system using the method of your choice.

tube or goog would be a great resource to with that question

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

-9

step-by-step explanation:

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
