Answer:
Step-by-step explanation:
Let the numbers be a and b.
<u>We have:</u>
and
- 0.12a = 0.2b, simplified as b = 0.6a
<u>Substitute b into the first equation:</u>
- a + 0.6a = 1600
- 1.6a = 1600
- a = 1600/1.6
- a = 1000
<u>Find b:</u>
Step-by-step explanation:
To go from A to M you need to go 4 to the right and 3 down. If M is the middle you'll need to do the same to get from M to B. So (2+4,-2-3)=(6,-5)
Triangle
Area = 1/2 b * h
Area = 1/2*15 * 9 = 1/2 * 135 = 67.5
Rectangle
Area = b * h
Area = 15 * 4
Area = 60
Trapezoid
Area = (1/2) * (b1 + b2)* h
Area = (1/2) * (15 + 18) * 4
Area = 1/2 * 33 * 4
Area = 66
Total Area
Total Area = 66 + 60 + 67.5 = 193.5 Answer
15x + 30y = -10....reduce by dividing by 5
3x + 6y = -2...same as first equation...same line ..means infinite solutions
