Answer:
2,4
Explanation:
Because a midpoint is the middle of the line
Step-by-step explanation:
3 balloons + 2 cakes = £19
=> 9 balloons + 6 cakes = £57 (multiply by 3)
9 balloons + 6 cakes = £57
- (9 balloons + 3 cakes = £42)
=> 3 cakes = £15, 1 cake = £5.
Therefore 3 balloons + 2(£5) = £19,
3 balloons = £9, 1 balloon = £3.
Hence each balloon is £3 and each cake is £5.

Step-by-step explanation:
Problem Green
Look at the white area. Where it meets the green border is the region of a quarter circle. So the quarter circle has a circumference of 1/4 * (2pi) r
r we are to take it, is 10/2 = 5 cm. It is 1/2 the side of the square..
So the perimeter of 1/4 green circle is (2/4) pi * 5 = 1/2 pi * 5 = 2.5*pi
There are 4 such areas.
So we have to multiply by 4
4 * 2.5 = 10 pi
The answer is 10*pi.
An alternate answer is 31.4 cm
Problem Two
<em><u>Large Circle</u></em>
Perimeter of the large circle = 2pi*r
r = 14 cm
Perimeter of the large circle= 2* pi * 14 = 28*pi
<em><u>Small Circle</u></em>
r = 14/2 = 7 cm
Perimeter = 2*pi*r
Perimeter = 2 * pi * 7
Perimeter = 14 pi
<em><u>Answer</u></em>
Total Perimeter = Small Circle + Big Circle
Total Perimeter = 14*pi + 28*pi = 42*pi
Your answer could be 42*3.14 = 131.88
If none of these are right, list your choices.

Answer:
5x +y = 20
Step-by-step explanation:
The equation of the parallel line will have the same x- and y-coefficients. The constant will be adjusted to make the equation true at the given point.
5x +y = 5(3) +(5) = 20
The parallel line is ...
5x +y = 20
