Answer:

There are 48 students in the science club.

Step-by-step explanation:

Total students: T=84

T=R+S→R+S=84   (eq. 1)

Students in Robotics club: R

Students in science club: S

The science club is 12 more students in the robotics club:

(eq. 2) S=12+R

How many students are in the science club?

S=?

Replacing eq. 2 in eq. 1:

(eq. 1) R+S=84

R+(12+R)=84

R+12+R=84

Adding like terms on the left side of the equation:

2R+12=84

Solving for R: Subtracting 12 both sides of the equation:

2R+12-12=84-12

Subtracting:

2R=72

Dividing both sides of the equation by 2:

2R/2=72/2

Dividing:

R=36

Replacing R by 36 in eq. 2:

(eq. 2) S=12+R

S=12+36

S=48

There are 48 students in the science club.

Answer:


Step-by-step explanation:

Let the Number of students in the Robotics club be x

So , the number of students in the Science club must be x+12

(Because it is given that the science club have 12 more students.)

Total number of students = 84

So ,

x+(x+12)=84

combining the like terms we get

2x+12=84

Subtract 12 from both sides

2x=72

Divide both sides by 2

x=36

So ,


Number of students in the Robotics club = 36

Number of students in the Science club =36+12 = 48

If five times the successor of a number is added to an original number the sum is 83
Alexus [3.1K]

Answer:

Let the original number be x

Successor is defined as the number which comes immediately after a particular number.

also, the  successor of a whole number is the number obtained by adding 1 to that number.

Then, the successor of a number x is, x+1

As per the given condition :

we have;

5(x+1)+x =83

Using distributive property on LHS (i.e, a\cdot(b+c)=a\cdot b+a\cdot c )

Then, we have

5x+5+x=83

Combine like terms;

6x+5=83

Subtract 5 from both the sides we get;

6x+5-5=83-5

Simplify:

6x=78

Divide both side by 6,

\frac{6x}{6} =\frac{78}{6}

Simplify:

x =13

Therefore, the original number x is, 13

If two angles are adjacent and have a sum of 180, then they are?
cupoosta [38]

They are most likely 90 degrees, due to the sharing of a common side and a common vertex. They really could be anything though. If given more details, I will give a better answer. I still would like Brainliest, however.
