3x + 4y = 5
<u>-5x - 4y = -11</u>
-2x = -6
-<u>2x</u> = <u>-6</u>
-2 -2
x = 3
3(3) + 4y = 5
9 + 4y = 5
<u> -9 -9</u>
4y = -4
<u>4y</u> = <u>-4</u>
4 4
y = -1
(x, y) = (3, -1)
Answer:
17.25
Step-by-step explanation:
You already know y = 72, so you could rewrite the equation to 72 = 4x + 3. To get to the answer, you need to find what X is. What you should do is subtract 3 from both sides, get 69, divide by 4 on both sides and get 17.25
I'm not sure if this is correct, but I hope this helped.
Answer:
5/36
Explanation:
Distance on a number line is basically difference between two numbers. So we subtract the two numbers. This can be solved on a calculator btw. 7/12 - √16/81 = 5/36.
These 2 angles are supplementary so we have
x+ 88 + x + 108 = 180
2x + 196 = 180
2c = -16
x = -8
the 2 angles are -8+88 and -8+108
that is 80 and 100.
Answer:
P(King) = 4/52 = 1/13
Step-by-step explanation:
As we know there are 52 cards in total from 2 to 10, and King, Queen, Jack, and Ace, with each of them are equal in numbers which is 4.
Total Number of Kings in the Deck of Cards = 4
P(King) = Number of Kings/Total Number of Cards
= 4/52 = 1/13
