4. I think 4 is 128
16x16=256 and divide that by 2 and its 128
in the like term you can add directly and make it single fraction and in unlike term you have to take LCM of denominator .
Answer:
x - 80
Step-by-step explanation:
Ravi had x dollars in all.
x - 80
p(-5, 2)
the rule is x + 3, so add -5 + 3 = -2
the x coordinate of P' is -2
Answer: B
Explanation:
32 marbles in total.
18 red marbles
4 blue marbles
10 green marbles.
You are asked what part of Osteen's marbles are red?
Probability = number of possible outcomes/total number of out outcomes.
P(Red) = 18/32 = 9/16
Both, 18 and 32 are divisible by 2 which gives 9/16. Since 9/16 cannot be reduced any further, we live it as it is. If you wanted to plug this into a calculator that would give 0.5625 which is 56.25% of Osteen's marbles are red.
P(Blue) = 4/32 = 1/8. 1/8 = 0.125 which 12.5% of his marbles are blue.
P(Green) = 10/32 = 5/16. 5/16= 0.3125 which 31.25 of his marbles are green. When you add 0.5625 + 0.125 + 0.3125 = 1 which is 100%. All probabilities add up to 1.
Hope this elaborate explanation helps.
