Answer:
see below
Step-by-step explanation:
defining variables:
since you are trying to find t shirt cost and jeans cost, your variables would be
the cost of the t shirt and the cost of jeans, denoted by any variable you want.
I'll use x and y since they are the most common variables (x = shirt y = jeans)
Equation
4 shirts + 5 jeans = 160 dollars
4x + 5y = 160 (the cost of 4 shirts + the cost of 5 jeans is $160)
the cost of 2 shirts + 6 jeans = $150
2x + 6y = 150

If you do .50 x 8 from each ticket being drawn and the probability you get 4
Answer:
t=15
Step-by-step explanation:
25% of 300=(25/100) . 300 [x%=x/100]
=75
500% of t= (500/100) . t = 5t [x%=x/100]
<em>Now,</em>
<em>75 = 5t</em>
<em>75/5=t </em>[divide both sides by 5]
<em>15=t</em>
