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.

Does anyone know what x is - 3/4 (x+2)=6

satela [25.4K]

-10.

Solution: Multiply the negative three fourths by everything in the parenthesis.

$- \frac{3}{4} x + ( - \frac{3}{2} ) = 6$

Add the negative three halves to both sides.

$- \frac{3}{4} x = \frac{15}{2}$

Multiply both sides by negative four thirds.

$x = - 10$

Base your answer on Betty is thinking of two consecutive integers whose sum is 41.

mel-nik [20]

Answer:

let the numbers be, x and x+1 ( as it is consecutive number the next number will have 1 more than the number )

sum = 41

so, x + ( x + 1 ) = 41

x + x + 1 = 41

2x + 1 = 41

2x = 41 -1 = 40

2x = 40

x = 40/2 = 20

x = 20

x + 1 = 20 + 1 = 21

so the consecutive numbers whose sum is 40 are, 20 and 21
