To solve for the area, you cannot solve for just half, so you first have to solve the whole entire area. A = πr².

π5² = 78.5

So, 78.5 is the answer to the circle area.

But half the circle is dividing the whole area by half.

78.5/2=39.25

So 39.25m² is the answer.

Answer: Refer to picture

Explanation: as the weeks go on, the number of sales increase. This means it has to be positively skewed, so graphs with the dots lower as it moves to the right can be knocked out

This leaves us with 2, since the rate of change in sales isn’t linear (22 -> 44 ->66) and is instead quicker at the start, it is not the straight graph, must be the curved one

Pls solve and show the steps, I'll give brainliest to whoever replies first and accurately

3(x-1) = 2x - y

3x-3 = 2x-y

3x-2x+y = 3

x + y = 3 ----> (1)

2(x+y) = 3+3y

2x + 2y = 3 + 3y

2x + 2y - 3y = 3

2x - y = 3 -----> (2)

make equation (1) and (2) together

x + y + 2x - y = 3+3

3x = 6

x = 2

now make x = 2 in equation (1)

x + y = 3

2 + y = 3

y = 3-2

y = 1

(x,y) = (2,1)
