Answer:
400
Step-by-step explanation:
because 380 + 20 is 400
Answer:
Step-by-step explanation:
Henry is 3 more than twice Nicholas' age. You can write this as :
H = 3 + 2N
Marcus is 9 less than 6 times Nicholas' age:
M = 6N - 9
Since Henry and Marcus are twins, this means H = N.
3 + 2N = 6N - 9
Add 9 to both sides
12 + 2N = 6N
Subtract 2N from both sides
12 = 4N
Divide both sides by 4 to find N.
N = 12/4 = 3
So there are 8 total cards, so you need to make your fraction out of 8. and there are 5 blue cards, so the probability of drawing one blue card is 5/8. but because you are doing a second draw, and NOT replacing the card you pulled the first time, you need to multiply 5/8 (the probability of drawing one blue card) and 4/7 (the second drawing).
5/8•4/7=5/14 which means the probability of drawing 2 blue cards in a row without replacing the first card is 5/14

9^1/3 * 3^x = 27^4/5
Rewrite 9 as 3^2
(3^2)^1/3 * 3^x = 27^4/5
Multiply the exponents in the first term:
3^2/3 * 3^x = 27^4/5
Use power rule to combine exponents:
3^(2/3 +x) = 27^4/5
Rewrite the 2nd term:
3^(2/3 +x) = (3^3)^4/5
Set the exponents only to equal:
2/3 + x = 3(4/5)
Solve for x:
simplify the right side:
2/3 + x = 12/5
Subtract 2/3 from both sides:
x = 26/15
