We write to expressions since there are two unknown here which is x and y. The first expression is the <span>sum of two numbers, x and y, is 12.
x + y = 12
The second expression is that the </span><span>difference of x and two times y is 6.
x -2y = 6
Therefore, the values of x and y are 10 and 2.</span>
The answer is y=1.2x because you can plug in 1.2x4 and get 4.8
Answer:
3
Step-by-step explanation:
A factor is 3 because 54xy / 3 = 18xy, 45x / 3 = 15x, 18y / 3 = 6y, and 15 / 3 = 5
Answer:
Step-by-step explanation:
Given : Suppose an urn has r red and w white marbles.
To find : Determine the probability that the marble is white ?
Solution :
Number of red marbles = r
Number of white marbles = w
Total number of marbles in an urn = r+w
Favorable outcome is getting the marble is white = w
So, Probability that the marble is white is given by
Answer:
f(1) = 3
Step-by-step explanation:
f(t) = t² - 1t + 3
we want to find f(1)
all we have to do is replace the t's with 1 and evaluate
f(1) = (1)² - 1(1) + 3
evaluate exponent 1² = 1
f(1) = 1 - 1(1) + 3
multiply
f(1) = 1 - 1 + 3
subtract
f(1) = 3
