What is a system of equations?

Answers

Answer 1
Answer:

Answer and Step-by-step explanation:

A system of equations is a group of equations that need to be manipulated in some way that will figure out the values of the variables.

The most common system of equations seen is a system of linear equations, which means that the degree of the variables is no more than 1. These can be solved using elimination, substitution, or even graphing, if applicable.

Hope this helps!

Answer 2
Answer:

Answer:

A system of equations is 2 or more equations that need to be solved. When you solve a system of equations, the answer is where the equations intersect on a graph. Sometimes there is 2 solutions (equations intersect twice), 1 solution (equations intersect once), no solution (equations don't intersect), or infinite solutions ( equations are the same).

They are usually solved using substitution, elimination, or simply looking at a graph to see where the lines intersect.

Some examples:

2x+3y=15

x-3y=3

y=x^2+1

2x-y= -4

In the cafeteria there are 7 teachers 48 girls and 45 boys What is the probability that a person chosen at random from the cafeteria is a boy

Answers

total peoples = 7 + 48+ 45 = 100
probability of boys = number of boys / total people
                             45/100 = 9/20
7+48+45
48+45=93
so 93% chance of a boy getting chosen

8''=8 inches
convert to inches

so
pythagorea theorem is
a^2+b^2=c^2
c=hypotonuse
a and b are legs

8 and 48 are the legs

Mrs.State needs help solving a math problem.Mrs.Krutchik’s planned to give 45 tests to 108 children. 67•/• of the students got F’s. The rest got A’s how many students got A’s in Mrs.Krutchik’s class?

Answers

Hey!

-----------------------------------------------

Steps To Solve:

  • Find number of kids who got an F.

67% = 0.67

108 x 0.67 = 72.36

  • Find the number of kids who got an A.

100 - 67 = 33% of student's passed.

33% = 0.33

108 x 0.33 = 35.64

  • We can round.

72.36 = 72 students got an F.

35.64 = 36 students got an A.

  • Check.

72 + 36 = 108

So our rounding is pretty accurate!

-----------------------------------------------

Answer:

33% or 36 student's got an A in Mrs. Krutchik's class.
