Step-by-step explanation:

<u>System of Linear Equations </u>

We have 3 unknown variables and 3 conditions between them. They form a set of 3 equations with 3 variables.

We have the following data, being

w = price of a sweatshirt

t = price of a T-shirt

h = price of a pair of shorts

19.

The first condition states the price of a sweatshirt is twice the price of a pair of shorts. We can write it as

$\displaystyle w=2h$

The second condition states the price of a T-shirt is $4 less than the price of a pair of shorts. We can write it as

$\displaystyle t=h-4$

The final condition states Brad purchased 3 sweatshirts, 2 pairs of shorts, and 5 T-shirts for $136, thus

$\displaystyle 3w+2h+5t=136$

This is the system of equations we need to solve for w,t,h

20.

To solve the system, we replace w in terms of h and t in terms of h. Those relations have been already written, so

$\displaystyle 3(2h)+2h+5(h-4)=136$

Operating

$\displaystyle 6h+2h+5h-20=136$

$\displaystyle 13h=156$

Solving for h

$\displaystyle h=12$

The other two variables are

$\displaystyle w=2h=24$

$\displaystyle t=12-4=8$

The product of two consecutive positive integers is 1,332. Explain how you can write and solve a quadratic equation to find the

taurus [48]

Product of two consecutive integer so this mean that x and y but y = x+1 than

x(x+1)=1332

x^2 +x -1332 =0 so bc. you get 36*37=1332 and 37x-36x=x so you can rewriting this quadratic factorized completlie

x^2 +x -1332 = 0

(x+37)(x-36)=0

x+37=0

x=-37 so the larger integer result that will be 37
