Is 9 a solution to 3y<27

Mathematics

arsen [322]3 years ago

No, because if y is in fact 9 then the expression 3y evaluates to 27 which is a false hence y cannot be 9 but rather y\in(-\infty,9).

Hope this helps.

Answer: No

Step 1: Rewrite the equation

3y<27

Step 2: Get y alone

To do this we need to divide both 3y and 27 by 3

3y<27

3y/3<27/3

y=9

Step 3: Substitution

We now know that y equals 9. Now let’s substitute this into the equation

3y<27

3(9)<27

27<27

Step 4: Determining the answer

Since 27 is not less than (27), 9 is not the solution for y. However, any number less than 9 would work for this equation

Hope this helps comment below for more questions :)

How to solve 4+|7-m|=5
notka56 [123]
When
|a|=b
assume
a=b and -a=b
so

4+|7-m|=5
minus 4 from both sides
|7-m|=1
assume
7-m=1 and
-(7-m)=1

7-m=1
minus 7 both sidees
-m=-6
times -1 both sides
m=6

-(7-m)=1
distribute
-7+m=1
add 7 to both sides
m=8

m=6 and 8

Find three consecutive odd integers such that the sum of the smallest number and middle number is 27 less than 3 times the large
serious [3.7K]

Answer:

17, 19, 21

Step-by-step explanation:

If we denote the smallest number as x, then the middle number will be x + 2 and the largest number will be x + 2 + 2.

The equation is:

x + (x + 2) = 3 * (x + 2 + 2) - 27

2x + 2 = 3x + 12 - 27

2x - 3x = 12 - 27 - 2

-x = -17

x = 17

The numbers are: 17, 19, 21

Let's check to be sure:

17 + 19 = 36

3 * 21 - 27 = 63 - 27 = 36
