When doing an equation like this, you first need to isolate the variable (x).
In this case, you would add the 2 on both sides
making the equation >> x - 0 = 11
you’d drop the zero because it has no value and you get your answer:
x = 11

AnswEr:

Add the two, to both sides. -2+2=0

So, the equation would like like this

x -2= 9

+2 +2

Then solve, the 2’s cancel out leaving you with x by itself. Finishing the equation to look like this-> x=11

Talia tossed a penny many times. She got 20 heads and 80 tails. She said the experimental probability of getting heads was 20 80
iragen [17]

Answer:

the experimental probability is 1/5

Step-by-step explanation:

This is because one to calculate the experimental probability one has to divide the favorable events over the possible events, and those that Talia did were the favorable events divided the non-favorable events

20 heads and 80 tails

Faborable events = 20

Possible events = 20 + 80 = 100

20/100 = 1/5

Answer:

rakamları farklı,üç basamaklı iki farklı sayının çarpımı "*en az*" kaçtır dediğine göre ilk olarak rakamları farklı üç basamaklı en küçük sayiyi bulmalıyız. Rakamlari farklı üç basamaklı en küçük doğal sayi:102 dir

şimdi birbirinden farklı iki sayı dedigi için ikinci sayıya 102 diyemeyiz o yüzden biz de 102den farklı en küçük 2. sayiyi bulmalıyız. O zaman 2. sayımız 103 olur

102×103=10 506 olur

sin35 = x/20

0.574 = x/20

cross multiply

x = 20(0.574)

x = 11.48

Round to the nearest tenth.

x = 11.5
