Answer:
Step-by-step explanation:
I can not see your answers to choose but with this equation for 2 variables, you can replace the values of x and y and see if that is right or not.
For example, to know (-2,5) is a solution, you replace x= -2 and y= 5
into this equation: -3x -y = 6
and you have: -3*(-2) -5 =6
or 6-5 =6, and you find that is impossible, so (-2.5) is not a solution.
Hope you understand it
If 45% don't want uniforms, it means that 45 out of 100 students don't want them, so the probability is 45/100 = 9/20
And 55% want unifrms, so the probability = 55/100 = 11/20

Answer:
Answer:
33.14\°
Step-by-step explanation:
Let
Y ----> field of vision that Yash's camera would need
we know that
Applying the law of sines
\frac{sin(Y)}{25}=\frac{sin(41\°)}{30}
Solve for sin(Y)
sin(Y)=\frac{sin(41\°)}{30}(25)
Y=sin^{-1}[\frac{sin(41\°)}{30}(25)]
Y=33.14\°
Answer:
Inspection fee = $50
h = 2 hours
Step-by-step explanation:
Let
x = the inspection fee
Charge per hour = $22
Number of hours = 4
A customer with a coupon for 40% off the inspection fee
This means the customer paid 60% of the inspection fee
118 = 60% of x + 22(4)
118 = 0.6x + 88
118 - 88 = .6x
30 = .6x
x = 30/0.6
x = $50
Inspection fee = x = $50
How many hours are worked when a customer pays $94 without a coupon?
94 = 50 + 22h
94 - 50 = 22h
44 = 22h
h = 44/22
h = 2 hours
