Answer:
Yes
Step-by-step explanation:
This is true because it is asking you if this is less than or EQUAL TO. 4 = 4, making it true.
N is the same as 17, so it equals 17.
Answer:
6 + 7 + 8 = 21
Step-by-step explanation:
6, 7, and 8 are consecutive integers.
6 + 7 is 13. 13 + 8 = 21. So, 6 + 7 + 8 are consecutive integers that equal 21.
Answer:
1 or 9.
Step-by-step explanation:
A coefficient is "a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g. 4 in 4xy)".
So, in this case, the coefficient of 9x would be 9.
The coefficient of x^2 would be 1.
Hope this helps!
Answer: y=2.7
Step-by-step explanation:
Since x=9y and substitution,
plug the 9y in where x is in the equation like so,
9y-5=20
Now get the variable by itself
To do this you add 5 to both sides of the equal sign
5+(-5) cancels out and 20 +5 =25
Now isolate the varaible by dividing 9y from both sides
So, 9y=25
9/9=1 so you leave it as y
and 25/9 is 2.77777
therefore y=2.7
