From the given information:
Range Number of values
1 - 5 3
6 - 10 1
11 - 15 4
16 - 20 5

Here you must do mult. and div. BEFORE add'n. and subtr'n.
<span>23 + 5 × 10 ÷ 2 – 33 + (11 – 8)
Mult 5*10, and then div. the result by 2. Then you will have
23 + 25 - 33 + 3
This simplifies to: 51-33 = 18</span>
Answer:
35 - 45x
Step-by-step explanation:
-7(-5) + -7(8x) + 11x => 35 - 56x + 11x => 35 - 45x
Answer:
8/13
Step-by-step explanation:
There are total 26 red cards in the deck of 52 cards.
There are also 12 face cards in the deck ( which is 6 of them are red, while 6 of them are black)
Since we only need either one of them, 26 + 6 = 32
The probability of drawn a card that either red or a face card is 32/52
The simplest form of this fraction is 8/13.
It’s a great way to write numbers that are very big numbers or very small numbers.
Have a great day!
