Answer:
160 in²
Step-by-step explanation:
20 * 16 / 2
if we wouldn't devide with 2, we would calculate the rectangle around the quadrilateral
To add: add the absolute values of the integers
Can you please and comma's? Without commas everything is confusing.
1st serving: 2/3 * 1/2 = 2/6 or 1/3
2nd serving: 1/3 * 1/2 = 1/6
3rd serving: 1/6 * 1/2 = 1/12
4th serving: 1/12 * 1/2 = 1/24
5th serving: 1/24 * 1/2 = 1/48
1/3 + 1/6 + 1/12 + 1/24 + 1/48
1/3 * 16/16 = 16/48
1/6 * 8/8 = 8/48
1/12 * 4/4 = 4/48
1/24 * 2/2 = 2/48
1/48 * 1/1 = 1/48
16/48 + 8/48 + 4/48 + 2/48 + 1/48 = 31/48
Bobby ate 31/48 of the cake in total.
2x + 5y = 4
5y = -2x + 4
y = -2/5 x + 4/5
parallel lines have same slope so slope = -2/5
equation
y +4 = -2/5 (x - 5)
y = -2/5 x + 2 - 4
y = -2/5 x - 2
answer is D
y = -2/5 x - 2
