Answer: Each shirt costs $1.25, and each hat costs $2.5.
Step-by-step explanation:
Let x= Cost per T-shirt, y = Cost per Hat.
As per given,
3x+3y=11.25 (i)
4x+2y=10 (ii)
Multiply 4 to equation (i)
12x+12y=45 (iii)
12x+6y= 30 (iv)
Eliminate (iv) from (iii), we get
6y= 15
⇒ y = 2.5
Put value of y in (i)
3x+3(2.5)=11.25
⇒3x+7.5=11.25
⇒3x= 3.75
⇒x= 1.25
Hence, each shirt costs $1.25, and each hat costs $2.5.
The 3 has no relation to time. Therefore, it is the starting position of the ball. Since the expression is the height, in feet, of the ball above the ground, the 3 means that the ball started 3 feet above ground when thrown.
For future knowledge, the t^2 means that -16 is the initial acceleration of the ball, and the t means that 40 is initial velocity.
Answer:
Step-by-step explanation:
- is the application of probability theory, a branch of mathematics, to statistics, as opposed to techniques for collecting statistical data.
- the study and manipulation of data, including ways to gather, review, analyze, and draw conclusions from data.
The equation is on y and x. We need to prove X+Y=100
Step-by-step explanation:
If the value of X=40,
Then value of Y could be 100-40 because the total count is 100.
Y=60.
Verification done by the given equation.
X+Y=100
Y=100-X
Y=100-40
Y=60
Therefore the value of the Y is 60
