Explanation:
This is a triangular prism. Its faces are triangular, but the <em>lateral</em><em> </em>faces are rectangular. All prisms will have lateral faces shaped as rectangles. Do not <em>ever</em> forget this.
I am joyous to assist you at any time.
3x - 4y = 18 ⇒ 3x - 4y = 18
2x + y = 1 ⇒ 8x + 4y = 4
11x = 22
11 11
x = 2
2x + y = 1
2(2) + y = 1
4 + y = 1
- 4 - 4
y = -3
(x, y) = (2, 3)
First let us determine the total number of combinations that
can be made from these pair. The number of combinations can simply be
calculated by multiplication, so:
Combination = 4 * 4 = 16
Since we know that for each shirt color, there is a
corresponding sock with the same color. So there are 4 matching pairs.
Therefore the unmatching pairs are 12. Calculating the probability to get
unmatching pair would be:
Probability of unmatching pair = 12/16 = 0.75
Interpretation: There is a 75% probability that his socks
and shirt wont match.
To solve the equation, we can first take 17.1 to the right hand side, changing the minus to addition :
1/6x -17.1 = 18
1/6x = -18+17.1
1/6x = -0.9
To take away the fraction, we multiply both sides by 6 so that 1/6 can be taken away to solve the equation:
1/6x = -0.9
1/6x x 6 = -0.9 x 6
6/6x = -3.6
x = -3.6
We can also turn the decimal number into fraction to solve the equation in fraction:
-0.9
= -0.9 x 1/10
= -9/10
To solve the equation:
1/6x = -9/10
x = -9/10 x 6
x = -36/10
x = -18/5
x= -3 3/5
Therefore, x = -3.6 or -3 3/5.
Hope it helps!
