Do u understand ?
Answer:
2. power
4. tenth
20. hundred-thousandth
40. 5.063
50. 67/10
Step-by-step explanation:
20. If the underlined digit is the zero, the answer is "hundred-thousandth." It's hard to tell from the picture if zero is the underlined digit.
40. 5 and 63/1000 = 5 + 63/1000 = 5 + 0.063 = 5.063
50. 6.700 = 6700/1000 = 67/10
Answer:
Find out the numbers .
To prove
Let us assume that one number be x.
Let us assume that second number be y.
As given
The sum of two numbers is 30.
Than the equation becomes
x + y = 30
Their difference is 6.
x - y = 6
Thus two equation are .
x + y = 30 and x - y = 6
Subtracted x - y = 6 from x + y = 30
x - x + y - (-y) = 30 - 6
y + y = 24
2y = 24

y = 12
Put in the x - y = 6
x - 12 = 6
x = 6 + 12
x = 18
Therefore the two numbers are 12 and 18 .
