4x+1=13
2x+y=8x-2y

4x+1=13 (subtract 1 from both sides of the equation)
4x=12 (now divide by 4 both sides of the equation)
x=12/4=3

2x+y=8x-2y same as
y+2y=8x-2x
3y=6x

when x=3, then 3y=6x is
3y=6×3
3y=18 (divide by 3 both sides of the equation)
y=18/3

y=6

answer: y=6

6 people sharing 40 lbs of gold evenly. How many do they get? Then subtract 1 2/3 from the result of the problem above &amp; sim
r-ruslan [8.4K]

Answer: 6

Step-by-step explanation:

Given Data:

Number of people = 6

Amount of Gold to be shared = 40lbs

Subtract 2/3 from your answer.

Therefore

If six people are to share 40lbs of gold evenly

= 40lbs / 6

Divide through by 2

= 20lbs / 3

= 20lbs / 3 - 2/3

= 18/3

= 6

Each person would get approximately 6lbs of gold

What is the solution of 2x/5−x/2=40 ?
mrs_skeptik [129]
2x/5 - X/2 = 40
LCD = 10

2•(2x/5) - 5•(X/2) = 40
4x/10 - 5x/10 = 40
4x-5x/10 = 40
-X/10 = 40
10•(-X/10) = 40 • 10
-X = 400
-X/-1 = 400/-1
X = -400.

I believe the solution is that X = -400.

Out of 180 students, 50 students play Piano, 68 play Guitar, and 59 play Flute
MaRussiya [10]

Answer:

Step-by-step explanation:

A Venn diagram depicts the logical relationships between two or more sets of elements by using alternating circles or other shapes. They're often used to visually arrange information, showing how objects are similar and different. In the fields of mathematics and statistics, Venn diagrams, also known as "set diagrams" or "logic diagrams," are commonly used.

From the given information:

Since we are to represent the given question into a Venn diagram, the diagram is being attached in the image below.

From the image below, we represent:

P =students that played Paino

G = students that played guitar

F = students that played flute

P = 50

G = 68

F = 59

(PUG) -35

(PUF) = 59

(GUF) = 40

since the value of (PUGUF) is not given, we represent it with x.

See the attached image below for diagrammatic representation of the Venn diagram.
