Is 9 a solution to 3y<27

Answers

No, because if y is in fact 9 then the expression $3y<27$ evaluates to $27<27$ 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

Divide 5/3 by 1/4

A.3/20
B.5/12
C.4/9
D. 2 2/5

Answers

We flip the 2nd fraction and multiply.

5/3 * 4/1 = (5 * 4)/(3 * 1) = 20/3 = 6 2/3

So the correct choice should be 'none of the above' unless you made a mistake in your question.

$(5)/(3):(1)/(4)=(5)/(3)\cdot(4)/(1)=(5\cdot4)/(3\cdot1)=(20)/(3)=(18+2)/(3)=\boxed{6(2)/(3)}\n\nfrom\ comment:\n\n(3)/(5):(1)/(4)=(3)/(5)\cdot(4)/(1)=(3\cdot4)/(5\cdot1)=(12)/(5)=(10+2)/(5)=\boxed{2(2)/(5)}\leftarrow answer\ \boxed{\boxed{D}}$

What is the value of the expression 6+18÷3×4

Answers

Hi! Ok so you use PEMDAS to figure these out.
So first we can cancel out parenthesis and exponents since there are none in this equation.
Now we do multiply and divide from left to right.
So first 18/3=6
So 6+6*4
Now we do 6*4=24
Now add and subtract
Then 6+24=30
So your answer is 30

it would be 30 cuz of the PEMDS
18 ÷ 3 =6
3 × 4 = 24
24 + 6 =30

Hye Sun has a modern coffee table whose top is a triangle with the following side lengths: 8 feet, 3 feet, and 5 feet. Is Hye Sun's coffee table top a right triangle?

Answers

you can check this by using the Pythagorean theorem

8²-5² = 39

3² does not = 39 therefore this is not a right triangle

What is the slope-intercept form of the function that contains the point (6, 2) and has a slope of 3?y= ____ x+ ____

Answers

The general formula: y=mx+b

(6,2) ⇒ x=6,y=2
m=3
b=?

2=3*6+b
2=18+b
b=-16

y=3m-16
