Write and solve equations here. Let the two numbers be x and y.
Then x + 3y = 24, and 5x + 3y = 36. Solve this system of linear equations.
Note that the first equation can easily be solved for x. Then x = 24 - 3y. Subbing 24 - 3y for x in the 2nd eq'n, we get:
5(24 - 3y) + 3y = 36, or 120 - 15y + 3y = 36
-12y = 36 - 120, or -12y = -84
-84
Solving for y: y = ------- = 7
-12
If y is 7, then x is 24 - 3(7). Simplifying, x = 24 - 21 = 3.
Then the solution is (3, 7).
By all means insert 3 for x and 7 for y in either of the original equations. If that equation comes out to be true, you'll know your solution is correct.
X y
0 0
1 5
2 10
3 15
The answer is y = 5x
we can check this by plugging in the numbers from the table:
5 = 1(5)
5 = 5
This makes this answer correct because it makes the equation true.
Answer:
Step-by-step explanation:
For a radical equation, the unknown or the variable is located under the radical sign.
In this case our variable is x.
From the given options, is the only radical equation.
The last equation, is not a radical equation because the number (13) under the radical sign is constant.
The 3rd choice is correct
Answer: 3/64
Step-by-step explanation: I think you ask 3/4 divided by 32/2 if you are the answer is 3/64. How to divided is first simplify the expression, if possible, by canceling the common factors. But if your asking me to do 32/2 divided by 3/4 the answer is 64/3 if you want it to be an improper fraction but if you want it to be a mixed fraction it would be 21 1/3. How to divided is first simplify the expression, if possible, by canceling the common factors.
Probability is a numerical description of how likely an event is to occur or how likely it is that a proposition is true.
