Answer:
3x=2y
Step-by-step explanation:
subtract on from each side 4x-1=1-1+2y=3x+2y
Answer:
9 : 10
Step-by-step explanation:
First the ratio will be 63 : 70
Now, we have to simplify! The GCF (greatest common factor) is 7, so let's divide both numbers by 7 to maintain equality.
63/7 = 9
70/7 = 10
9 : 10 is the final answer!
Answer:
-1/6
Step-by-step explanation:
24x=-4
X=-4/24
X=-2/12
X=-1/6
Answer:
look, equation ii and vi are contradicting each other....
Step-by-step explanation:
after eliminating those equation you can find the value of x and y.
y=-6
x=3
Assuming you mean y = 200 - 16t^2, we have all the required information needed to solve this problem. The y-value is the height of the building and the t-value represents the number of seconds after the shoe fell off.
Since we are trying to solve <em>for t</em>, we will be using our y-value. The problem states that we landed on a building with a height of 31 feet. We can plug this into the y-value, since that is what y is defined as (the height of the building).
Now we have:
31 = 200 - 16t^2
We can solve this to find t:
-169 = -16t^2
169 = 16t^2
10.5625 = t^2
3.25, -3.25 = t
We have found two answers for t. However, the negative value is not a solution because we can not have a negative number of seconds. Thus, 3.25 is the only value of t which works for this problem.
Since t is the value we are trying to find, we have our answer. The shoe hits the building after 3.25 seconds.
