Answer: 2. Z=5000-2713.5=$2286.5
Step-by-step explanation:
Sub y=2713.5 into z=5000-y
Put one unit at top and other unit bottom. X for unknown
5 gallon / 20 hours = x gallons / 48 hours
Cross multiply
20x = 5*48
20x = 240
X= 12
Answer:
12.56 units 2
Step-by-step explanation:
area=pi(r^2)
2(2)=4
4(3.14)=12.56
Answer:
x = 16°
4x-7 = 57°
3x+4 = 52°
5x-9 = 71°
Step-by-step explanation:
All angles of any triangle add up to 180°, so if we add up each equation and set it equal to 180 we can find x.
4x-7 + 3x+4 + 5x-9 = 180
Simplify by combining like terms.
12x-12 = 180
Then, do inverse operations to find x.
12x=192
x=16
Now that we found x, we can substitute 16 for x in each angle equation in the triangle.
4(16)-7 = 57
3(16)+4 = 52
5(16)-9 = 71
So to solve this you simply have to solve 3.4 x 3.
Multiply the decimal and you get 1.2, multiply the whole numbers and you get 9. 9 + 1.2 = 10.2 or 10 1/5 cups, hope this helps!
