6x+7y=4x+4y complete the missing value in the solution to the equation (?,-4)

Mathematics
1 answer:
Ainat [17]3 years ago
3 0

we have

6x+7y=4x+4y

we know that

the solution is ----> (x,-4)

substitute the value of y=-4 in the equation

6x+7*(-4)=4x+4*(-4)

6x-28=4x-16

Combine like terms

6x-4x=28-16

2x=12

x=12/2

x=6

therefore

<u>the answer is</u>

the missing value is x=6

The local public pool is a rectangle with two semicircles.
Reptile [31]

The area of the surface of the pool is 7322.64 m².

<h3>What is Area of rectangle?</h3>

The area of rectangle is product of length and its breadth.

i.e., length * breadth

Given: Length = 100 m, Width = 52 m and Diameter = 52 m

Area of rectangle,

= 100 × 52

= 5200 m²

Now,

Area of semicircle = 1/2 × πr²

=1/2 × 3.14 × 26²

= 1061.32 m²

Hence, area of the surface of the pool is

= 1061.32 + 1061.32 + 5200

= 7322.64 m²
