Kiran says that a solution to the equation x+4=20 must also be a solution to the equation 5(x+4)=100 Write a convincing explanat

Helen [10]

Answer:

x+4=20 is a solution to 5(x+4)=100.

Step-by-step explanation:

Following PEMDAS, divide 5 from both sides of the equation 5(x+4)=100, and you have x+4=20 remaining.

This means that both equations have the same solution.

Work out the area of this circle. Take pi to be 3.142 and give your answer to 1 decimal place

Rashid [163]

Step-by-step explanation:

I think you have forgotten to attach the question.

Anyways....

In order to find the area of a circle use the formula:

π $r^{2}$ Where r is the radius

For example the radius is 3cm. The area of the circle will be:

π × $3^{2}$

Since you have taken pi as 3.142...

3.142 × $3^{2}$

3.142 × 9

= 28.278

In order to find the answer to 1 decimal place, check the number next to the number right after the decimal. Is it a number greater than or equal to 5? then add +1 to the number.

= 28.3 $cm^{2}$
