Answer:
There are 52 cards in a deck… 12 of these are Face Cards (the J - Q - K of all four suits).
The probability of getting one of these is therefore 12 out of 52 — or 12/52, which is 23%. Not quite a 1 out of 4 chance, but close.
Answer:
Assuming you're doing these values in pairs:
1:9 = 1/9
3:4 = 3/4
35:410 = 7/82
4 = 4
Step-by-step explanation:
Step-by-step explanation:
When w=10, 7w=7×10=70
But the given value of 7w is 73.
So, the given value is not a solution of the equation.
Answer:
Step-by-step explanation:
Let the numbers be x and y
<u>Three times the first number minus two times the second number equals -7:</u>
<u>The second number equals one less than negative three times the first number:</u>
<u>Substitute y in the first equation and solve for x:</u>
- 3x - 2(-3x - 1) = -7
- 3x + 6x + 2 = -7
- 9x = -9
- x = -1
<u>Find the value of y:</u>
- y = -3(-1) - 1
- y = 3 - 1
- y = 2
The numbers are -1 and 2
