Mathematics

horsena [70]3 years ago
4 0
Y=1/2x+2
y=-x+5
subsitute since they both equal y
1/2x+2=y=-x+5
1/2x+2=-x+5
subtract 2 from both sides
1/2x=-x+3
multiply both sides by 2
x=-2x+6
add 2x to both sides
3x=6
divide both sides by 3
x=2
subsitue
y=-x=5
y=-2+5
y=3

x=2 and y=3
solution in (x,y) form is (2,3)

A chess tournament starts at 12:30 p.m. and ends at 5:00 p.m. Does the tournament last more than 5 hours? Use the drop‐down menu
pychu [463]

The tournament does not last more than 5 hours because the duration of the tournament is 4.5 hours.

<h3>What is an arithmetic operation?</h3>

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

We have a chess tournament starts at 12:30 p.m. and ends at 5:00 p.m.

The difference between 12:30 p.m. and 5:00 p.m. can be calculated after changing time into 24 hours clock

12:30 p.m. = 12 hours 30 minutes = 12.50

5: 00 p.m. = 17 hours 00 minutes = 17.00

Difference between them:

= 17.00 - 12.50

= 4.5 hours

4.5 < 5

Thus, the tournament does not last more than 5 hours because the duration of the tournament is 4.5 hours.

The length of a rectangle is x. The width of the rectangle is (x + 10). Write an expression for the area of the rectangle.
Fed [463]

Answer:

A=x^2+10x

Step-by-step explanation:

<u>Area of a Rectangle</u>

Given a rectangle of width W and length L, its area can be calculated with the formula:

A = WL

We are given the length of a rectangle is L=x and the width is W=x+10, thus the area is:

A=x(x+10)

Multiplying:

\mathbf{A=x^2+10x}
