Solve for x to find the weight of the elephant on planet B. Cross multiply; (100)(x) and (3)(2200).
You now have:
100x = 6600.
Divide both sides by 100.
x = 66
The elephant would weigh
66 pounds on planet B.
Answer:
136 square cm
Step-by-step explanation:
Area of rectangle = 18x7=126 square cm
Area of triangle = 1/2x(11-7)x(18-13) = 1/2(4)(5) = 10 square cm
126+10 = 136 square cm
Answer:
The slope is -4/7 and the y-intercept is -8/7.
Step-by-step explanation:
y+4=-4/7(x-5)
7y+28=-4(x-5)
7y+28=-4x+20
7y=-4x-8
y=-4/7x-8/7

Step-by-step explanation:
Answer:x=31
angle AOC = 124
angle BOC = 56
Step-by-step explanation:
We first need to solve for x to solve the rest. We would normally solve for x by setting 2 equations equal to each other, in this case however, we know that the two angles are adjacent and in total add up to 180. Therefore we combine like terms of both angles, and set them equal to 180.
So, we do
3x+31+2x-6=180 We will combine like terms
5x+25=180 Now we will do inverse operations
5x=155
x=31
We plug x into angle AOC to solve for it
3(31)+31= 124
180-124=56 or angle BOC because the whole angle is 180, and if we subtract 124 from 180 we get the remainder which is angle BOC
Or if you want,
2(31)-6=56
