There are total 18 marbles in a bag.
P(red marble) first drawn:
3/18=1/6
P(red marble) second drawn:
2/17
2/17×1/6=1/51. As a result, the probability of drawing two red marbles is 1/51. Hope it help!
Answer:
d) 5 lollipops each and 3 left over
Step-by-step explanation:
To find out how many each of them get, you need to find the total amount of lollipops to be shared equally.
Total No. of lollipops = 3 + 5 + 7 + 4 + 9
= 28
No. of lollipops each of them get = 28 ÷ 5
= 5 R3
(To find the remainder of something, you have to know how much is the quotient (which is 5 in this case), multiply it by the divisor (which is also 5 in this case) then minus that number from the total (which is 28 in this case) )
Additional working:
5 × 5 = 25
28 - 25 = 3 (remainder)
Alright, so to understand algebra
use PEMDAS
parenthasees
exponents (square roots count as exponents)
multiply or divide
add or subtract
basically try to isolate the unknown/vareable/xterm
so
3(2x-1)-10=8+5x (assuming you meant to type 8+5x and not 8=5x)
first distribute using distributive property
a(b+c)=ab+ac
3(2x-1)=3 times 2x+3 times -1=6x-3
6x-3-10=8+5x
add like terms
6x-13=8+5x
subtract 5x from both sides
x-13=8
add 13 to both sdies
x=21
