Answer:38 t-shirts
Step-by-step explanation:
P=30t-640 main street
p=25t-450 broad street
30t-640=25t-450
30t-25t-640=-450
5t-640+640=-450+640
5t/5=190/5
t=38

I can be organized 4 different ways
The solution is where the two lines cross each other.
They cross at (4,-3)
So probably put it into slope intercept form
y=mx+b
m=slope
we have slope=3 so input
y=3x
tada
bascially we input x or number of yers and get an ouput of height or y
Answer:
a)
b)
c)
d)
Step-by-step explanation:
We will use the following trigonometric identities
.
Recall that given a right triangle, the sin(theta) is defined by opposite side/hypotenuse. Since we know that the angle is in quadrant 2, we know that x should be a negative number. We will use pythagoras theorem to find out the value of x. We have that
which implies that . Recall that cos(theta) is defined by adjacent side/hypotenuse. So, we know that the hypotenuse is 7, then
b)Recall that , then using the identity from above, we have that
c) Recall that . Then,
d) Recall that and . Then
