The odd natural number which is mentioned as X is 175.
<u>Step-by-step explanation:</u>
- By prime Factorization method .
- Step 1 : The prime factor for 40 is = 2×2×2×5.
- Step 2 :The prime factor for 1400 is = 2×2×2×5×5×7.
- Step 3 : the prime factor for the unknown natural odd number is to be find by comparing the factors of 40 and 1400.
- Step 4 : Lcm is known as least common multiple.
- Step 5 : Thus we can see the 5×5×7 in 1400 as different factors from the factors of 40.
- Step 6 : So lets multiply the factors we get number 175 which satisfies the condition of the odd number.
- Step 7 : The prime factors of 175 are 5×5×7.
Answer:
see below
Step-by-step explanation:
Since 2x appears on the left side of both equations, that term can be eliminated by subtraction, which is what the first choice suggests.
The result will be ...
3y = 7 -4y +5 . . . . . . . . . second equation subtracted from the first
7y = 12 . . . . . . add 4y
y = 12/7 . . . . . . divide by 7
__
However, the fact that 2x is by itself on the left side of the second equation suggest that <em>substitution</em> may also be a good option. Perhaps an equally good first step is to use the expression in the second equation to substitute for 2x in the first:
(4y -5) +3y = 7
Either way, the resulting equation is 2-step.
7y = 12 . . . add 5
y = 12/7 . . . divide by 7
___
The other suggested "first steps" do nothing useful.
If we are ordering these from least to greatest, it would be as follows:
-7, -1, 1, 7
Remember that the 'smaller' negative numbers are those that are further away from 0.
Then, if we need to add inequality signs, it would be as follows:
-7 < -1 < 1 < 7
Basically, we are saying that -7 is less than -1, which is less than 1, which is less than 7.
Hope this helps!! :)
