Answer:
3/4
Step-by-step explanation:
1/2 the deck is red cards.
1/4 of the deck is spades.
There are no spades that are red cards, so the probability of drawing a red card or a spade at random from a well-shuffled deck is ...
1/2 + 1/4 = 3/4
Answer:
w = -7z/2
Step-by-step explanation:
We need to solve for w in terms of z.
The equation given is:
5w + 9z = 2z + 3w
Collect like terms:
5w - 3w = 2z - 9z
2w = -7z
w = -7z/2
She would have $7160.86 left over in cash here's why.....
she starts off with $8,322.65 and spends $830.98 on rent $8,322.65-$830.98= $7,491.67
then spends $210.36 on food and another $120.45 on gas
$7,491.67-$210.36= $7,281.31 - $120.45= $7,160.86 <---- Left over $
The rule is 3^x.
Check: 3^1 = 3; 3^2 = 9; 3^3 = 27 and 3^4 = 81
