Answer:
1/10
Step-by-step explanation:
There are 4 prime numbers from 1 to 10 (2,3,5,7). This makes the probability of getting a prime number as 4/10 = 2/5.
The probability of getting one tail is 1/2, making the proability of getting 2 to be (1/2)^2 = 1/4.
Multiply both probabilities together, and you get 2/5 * 1/4 = 1/10
Answer:
5x = 14
Step-by-step explanation:
If 5 yards of fabric is $14 you need an equation that would solve how much 1 yard of fabric costs. You can say 5x = 14 or x = 2.8 which means that one yard of fabric (1x or just x) is $2.80.
The third answer
1 quarter, 6 dimes, 1 nickel, 7 pennies
<u>Answer:</u>
It's X=2
<u>Working out:</u>
<u>(left one):</u>
2(x+3)=10
2x+6=10
2x=10-6
2x=4
x=2
Working out:
(right one):
2(x+3) must be all divided by 2 so it will be x+3 and same for 10, it will be 5 so...
x+3=5
x=5-3
x=2
