I think the answer is D. But I am not sure if that's the right answer.
Answer:
x>-2
Step-by-step explanation:
Hi there!
We are given the inequality 7+7(x+4)>21, and we want to solve it
Solving an inequality is a lot like solving an equation; we want to isolate x on one side by itself.
So to start, we'll preform the distributive property on 7(x+4) (multiply x by 7, then multiply 4 by 7 and add those two together).
7+7x+28>21
Now combine like terms.
7x+35>21
Subtract 35 from both sides
7x>-14
Divide both sides by 7
x>-2
Hope this helps!
Answer:
<em>x < 4</em> is your answer
Step-by-step explanation:
all you have to do +3 on both sides
divide 12/3
(Answer is above)
since 9 isnt greater than 9, techincally the answer is any number greater than 4.
Answer:
It will take 8 hours for the 5 workers to complete the same job.
Step-by-step explanation:
The amount of work done is the same for both crews.
Work = time * workers
Work = 10 * 4
Work = time * 5
Set the two equal
10 * 4 = time * 5
Divide each side of the equation by 5
10*4/5 = time *5/5
8 = time
Answer:
3. D x÷y
4. B an irrational number
Step-by-step explanation:
3. When you divide a number, the answer is smaller than subtracting it, adding it, or multiplying it
4. 13-5=8 and the square root of 8 is 2.828...
