Answer:
answer a
Step-by-step explanation:
< ![18](https://tex.z-dn.net/?f=18)
- Let's isolate
on one side of the equation. Ignore the inequality for now. We'll deal with that later.
![4d-6=18\\4d-6+6=18+6\\4d=24\\\frac{4d}{4}=\frac{24}{4}\\ d=6](https://tex.z-dn.net/?f=4d-6%3D18%5C%5C4d-6%2B6%3D18%2B6%5C%5C4d%3D24%5C%5C%5Cfrac%7B4d%7D%7B4%7D%3D%5Cfrac%7B24%7D%7B4%7D%5C%5C%20d%3D6)
- Now, I'm going to bring back the inequality or < symbol. I only removed it when simplifying and isolating
, but if this confuses you, just do your math and keep the inequality there.
< ![6](https://tex.z-dn.net/?f=6)
- On a number line, this would include every number <em>less than </em>
, due to the < (less than) symbol. This disqualifies answers b and d because they are showing every number <em>greater than </em>
. But, how do we decide between answers a and c? - If a line has point at its beginning,
, then that means that every number <em>less than or equal to</em> [ ≤ ] 6 is being shown, but our equation just says <em>less than </em>[ < ] 6, so answer a is our correct answer.
Answer:
28 - 8= 20 ÷ 5 = 4
Step-by-step explanation:
Use distributive property. The answer is 4
Answer:
16 boxes
Step-by-step explanation:
160+50x=1000
Solve for the x and you'll get 16.8. Now, because you can't have a fraction of a box, and you can't go over the limit, the answer is 16 boxes.
(How to solve for x:
Get x by itself by subtracting 160 to both sides.
50x=1000-160
50x=840
Divide both sides by 50.
x=16.8)
