I'm not so sure because there is no solution to that equation
Step-by-step explanation:
Always start by solving the parenthesis equation and multiply, divide, subtract, or add before you get into adding. Next you add those 2 numbers together and when you look at the answer on the left and on the right.. when they are different numbers, you know there is no solution. I'm not sure if this helped and if it didn't I'm sorry.. I tried.

ASAP!!!! I WILL MARK YOU BRAINIEST!!! Two men decide to drive to a distant town, taking the same route. The first leaves 2 hours ahead of the second and drives at 60 km per hour, while the second man drives at 90 km per hour. How many hours will it take the second man to catch up with the first man?
Answer:
4 hours.
Step-by-step explanation:
If the first guy is driving at 60 km, in 2 hours he is 120 km away. The second guy, leave two hours after. He will drive and in 2 hours he is 180 km. now if the second car keeps going then
120+ 60 + 60 +60 + 60 = 360
180 + 90 + 90 = 360.
So, the two hours for the guy going at 90 km and another 2 hours is 4 hours, so it will take 4 hours for the second driver to catch up.

Miguel has to take two quizzes tomorrow. He has only enough time to study
for one of them.
• The history quiz has 4 true-or-false questions.
• The science quiz has 3 multiple-choice questions.
Miguel calculates the probability that he will get all the questions correct by
guessing.
To get 100% correct:
P(guess is correct)
History
Answer 4 of 4 correctly.
0.5
Science
Answer 3 of 3 correctly.
0.2
Miguel will study for the quiz on which he is likely to do worse by guessing.
Which quiz should he study for?
O
A. History, because he must get more questions correct.
B. Science,
C.History,
Answer:
Option B is correct.
Miguel should study for the Science quiz as he will do worse in that quiz by guessing.
Step-by-step explanation:
Miguel has to take two quizzes
1) 4 true or false questions on History with a 0.5 chance of acing the quiz
Expected number of correct questions = np
n = number of questions
p = probability of acing the test
Expected number of correct questions = 4 × 0.5 = 2
2) 3 multiple choice questions on Science with a 0.2 chance of acing the quiz.
Expected number of correct questions = 0.2 × 3 = 0.6
It is evident that guessing would yield a worse result in the Science quiz with less than 1 question expected to be correct than history, where he is still expected to get 2 questions correctly by guessing.
Hope this Helps!!!
