7 * 38 + 3*45 - 56
use order of operations
(7*38) + (3*45) - 56
266 + 135 - 56
=345
3 gallons because 3/4 of a gallon covers 1/4 of a wall so you multiply the amount of gallons used for a wall times 4 which is 12/4 (keep the denominator the same ) and then divide 12 by 4 which is 3 gallons
Answer:
(5r - 20)
Step-by-step explanation:
(3r + 14) + (Ar + B) = (8r - 6)
B = -6 - 14 = -20
A = 8 - 3 = 5
Answer: 1/67600
Step-by-step explanation:
probability that the code is 43MZ:
Probability = (Total Required outcome / total possible outcomes)
Possible outcomes (digit) = (00,.............. ..., 99)
2.) possible outcomes (alphabet) = (A, B,............... .., Z)
P(43MZ) = P(43) × P(M) × P(Z)
P(43) = 1/100
P(M) = 1/26
P(Z) = 1/26
THEREFORE ;
P(43MZ) = (1/100) × (1/26) × (1/26) = 1/67600
Answer:
number of chores
so tool and two are the same but one is different so when the one is different you figure out the answer more easier than it looks, if you just did there a steer on it you want just ignore the answer because it is hard and when you look at it you say that who are the same and another two are the same but one is different.
