Answer:
x = 32 y = 16 z = 64
Step-by-step explanation:
x is the 1st number
y is the 2nd number
z is the 3rd number
The first number is twice the second number so
x = 2 y
The third number is twice the first number.
z = 2 x
Their sum is 112
x + y + z = 112
Plus in what we know:
x + y + z = 112
2 y + y + 2x = 112
3y + 2x = 112 Let's solve for y and subtract 2x from each side
3y = 112 - 2x Divide both sides by 3
y = 
Now plug our answer back in to solve for x.
x = 2y
x = 2 (
)
x = (224 - 4x) / 3 Multiply each side by 3.
3x = 224 - 4x Add 4x to each side
3x + 4x = 224
7x = 224 Divide each side by 7
7x / 7 = 224 / 7
x = 32
Now we can solve for z.
z = 2x
z = 2 ( 32 )
z = 64
Now we can solve for the numerical value of y.
x + y + z = 112
32 + y + 64 = 112
96 + y = 112 Subtract 96 from each side.
y = 112 - 96
y = 16
Answer:
Euclid was a great mathematician and often called the father of geometry.
Step-by-step explanation:
Answer: A
Step-by-step explanation:
First, we know that each set has 20 kL, 20 L, and 20 ml. To know if they are in the order from greatest to least, we should make sure all three have the same units. Once we do, we can put them in order.
20 kL=20000 L
20 mL=0.02 L
20 L=20L
Now that we have made sure the units are all the same, we know that 20 kL is the greatest and 20 mL is the smallest. The final order is 20 kL, 20 L, 20 mL.
For the first one, the two in the middle apply. for the second one, they all apply
