What is a system of equation?A set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.
Given that, Bridgette plans to attend 4 cardio classes and 5 weightlifting classes, which will last a total of 339 minutes. Next week, she hopes to attend 3 cardio classes and 1 weightlifting class, which will last a total of 158 minutes.
Let number of minutes spend in cardio be c and that of in weightlifting be w,
Establishing the equations, we get,
4c+5w = 339....(i)
3c+w = 158...(ii)
Multiplying eq(ii) by 5 and then subtracting eq(i) from eq(ii)
(15c+5w = 790) - (4c+5w = 339)
11c = 451
c = 41
Put c = 41 in eq(ii)
123+w = 158
w = 35
Hence, Every cardio class lasts for 41 minutes and every weightlifting class lasts for 35 minutes.

Answer:
Probability in Maths:-
Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one. Probability has been introduced in Maths to predict how likely events are to happen.
Formula for Probability:-
The probability formula is defined as the possibility of an event to happen is equal to the ratio of the number of favourable outcomes and the total number of outcomes.
Probability of event to happen P(E) = Number of favourable outcomes/Total Number of outcomes
Probability refers to a possibility that deals with the occurrence of random events also can be state as all the events occurring need to be 1.

Aaron has a 28.7 m length of rope. He uses 6.7 m of the rope
to make a rope ladder for a playground. He cuts the remaining
rope into 2 equal pieces to make tire swings. How long is each
tire swing rope?
Answers
Answer:
first step is to minus 28.7 - 6.7=22 (I did the minus because I want to get the remaining length of the rope )
step 2 : is to divide 22 by 2 (because the question said they should divide it into two pieces )
then the answer you get from the division of 22/2 which is 11 that would be the final answer
meaning each tire swing is 11m

Emily has 4 1/2 cups of chocolate chips. Her cookie recipe requires 3/4 cup of chocolate chips. How many batches of cookies can Emily make?
Answers
Answer:
There are 6 batches of chocolate chip cookies that can be made.
Step-by-step explanation:
First, turn 4 1/2 cups into an improper fraction with a denominator of 4 (which is 18/4). Then, do 18/4 divided by 3/4 (or 18/4 times 4/3 and both 4s cancel). The result is 18/3 or 6 because 3 times 6 equals 18.
