Answer:
To begin this problem we call "the sum of the number" x. Now we have the equation 2(x)+5=20. This is the answer because it said to translate the equation. I think 2x+5+20 would be the correct translation.
Answer: 2 or more.
X and Y could be anything, so there are at least two answers
Probability=number of specific outcomes / total number of possible outcomes.
Probability of two events occurring is P(1)*P(2)
In this case:
P(BandE)=(3/12)(5/10)=15/120=1/8
P(BandE)=1/8 (12.5%)
Answer:
1,274
Step-by-step explanation:
5a^4 + 6b^3 when a = 4 and b = -1
~Substitute
5(4)^4 + 6(-1)^3
~Solve the exponents
5(256) + 6(-1)
~Multiply
1280 - 6
~Subtract
1,274
Best of Luck!
