Answer:
15 Nickels, 11 Pennies
Step-by-step explanation:
Simplify your life and take out the decimals
5*N + P = 86
P + 4 = N (4 more nickels than pennies)
By substitution of the second eq into the first: 5*(P+4) + P = 86
5*P + 20 + P = 86
6P = 66
P = 11, so N = 4 + 11 = 15
M=14.6 (is rounded to the nearest tenth.)
Answer:
john's age= x + 5
his sister's age= x
x + 5 + x = 150
2x + 5 = 150
2x = 150 - 5
2x = 145
x = 145 ÷ 2
x = 72.5
so, 72.5 + 5 = 77.5
john's present age is = 77.5
his sister's present age is = 72.5
X is the gcf so:
this is the maximum you can factor that too:
Answer: 1/8
Step-by-step explanation:
1) A B C D E F G H -> The probability of spinning a vowel is 2/8.
2) 1 2 3 4 5 6 -> The probability of rolling an even number on a standard dice is 3/6.
3. To find the probability of spinning a vowel and rolling an even number on a standard dice, we just have to multiply both of the probabilities:
2/8 * 3/6 = 6/48.
4. Simplify 6/48 and you get -> 1/8.
