Answer:

x = 1

y = 1

Step-by-step explanation:

3x + 2y = 5

3x - 2y = 1 (subtract these equations)

––––––––––––

4y = 4

divide by two

y = 1

input y = 1 the other equations

3x + 2 = 5

simplify

3x = 3

x = 1

Answer:

3x+2y=5.......(1)

3x-2y=1.........(2)

subtracting equation 1 by 2

3x+2y=5

3x-2y=1.

- +. =-

_________

3x-3y+2y-(-2y)=5-1

2y+2y=4

4y=4

y=4/4=1answer

adding equation 1 &2 we get

3x+2y=5

3x-2y=1

+

________

3x+3x+2y-2y=5+1

6x=6

x=6/6=1

:.x=1&y=1

A worker is constructing a concrete pad that has a radius of 6.3 metres, as shown below. Report a Problem ↻ Reload Image How man
Mariana [72]

The circumference of the pad to the nearest tenth is 39.6 meters

<h3>Formula for calculating the circumference of a circle?</h3>

The circumference of a circle is the arc length of the circle, as if it were opened up and straightened out to a line segment. It is also known as the perimeter of a circle.

The formula for calculating the circumference of a circle is expressed as;

C = 2πr

where

π = 3.14

r is the radius of the circle

Given the following parameters

π = 3.14

r = 6.3m

Substitute to have:

C = 2 * 3.14 * 6.3

C = 6.28 * 6.3

C = 39.564

Hence the circumference of the pad to the nearest tenth is 39.6 meters

Solve the equation. 2x+1/3+x-1/4=13/2
inessss [21]

The solution of the equation is x = 71 / 36.

<h3>How to solve an equation with one variable</h3>

Herein we have an equation with several rational constants and only one variable, x, which has to be cleared by using algebra procedures. The procedure is shown below:

2 · x + 1 / 3 + x - 1 / 4 = 13 / 2           Given

2 · x + x = 13 / 2 - 1 / 3 - 1 / 4            Compatibility with addition / Existence of additive inverse / Modulative property

3 · x = 71 / 12                                    Definitions of addition and subtraction / Distributive property

x = 71 / 36                                         Compatibility with multiplication / Existence of multiplicative inverse / Modulative property / Result

The solution of the equation is x = 71 / 36.
