Answer:
x - 18 > 6
x can be a number from 25 and up
Step-by-step explanation:
x can be a number from 25 and up because 25 - 18 = 7 > 6
and if you subtract 18 by any number above 25 then you will get a number greater than 6 every time
Answer:
Answer: 455 / 7
Step-by-step explanation: Three answer choices have the same quotient as 4.55 ÷ 0.7. Which one does NOT?
answer choices
455 ÷ 70
455 ÷ 7
45.5 ÷ 7
4.55 ÷ 0.70
The number resulting from the division of one number by another is regarded as quotient. For example, The quotient of 12 divided by 4 is 3.
And so, the first, third and last options on expansion by division all yield the same results in decimals (6.5) as that in the question (4.55 / 0.7 = 6.5) which is an indication that they have the same quotient.
Only the second option does not do so. 455 / 70 = 65
5x+3y=-9
-2x+y=8
The first step is the trickery (and quite frankly, hardest to explain) part. You need to multiply one equation by a number that will create one variable to be the negative version of the other...(Confusing, right? Don't worry, I'll show you)
We are going to solve for X first.
We will multiply the second equation by -3
5x+3y=-9
-3(-2x+y)=(-3)8
Now simplify:
5x+3y= -9
6x-3y= -24
Now combine the two equations (add them together)
11x= -33
Divide by 11
X=-3
Now plug X in to one of the first equations:
5(-3)+3y= -9
-15+3y =-9
3Y= 6
Y= 2
So your final answer is:
x= -3
Y= 2
Hope this helps!
To construct a line perpendicular to line AB and passing through an external point M.
Step 1:- Keep point A as center and draw a circle using compass opened with a width equal to radius AM.
Step 2:- Similarly, Keep point B as center and draw another circle using compass opened with a width equal to radius BM.
Step 3:- The two circles drawn so far would cut at two points, first point is M and second point is N.
Step 4:- Join the two points M and N using straightedge.
Step 5:- Therefore, we have a line MN that is perpendicular to line AB.
