Step-by-step explanation:
Let's solve the inequality step-by-step.
2x+3>23
Step 1: Subtract 3 from both sides.
2x+3−3>23−3
2x>20
Step 2: Divide both sides by 2.
![\bf \bold {\frac{2x}{2} } > \frac{20}{2}](https://tex.z-dn.net/?f=%20%5Cbf%20%5Cbold%20%20%7B%5Cfrac%7B2x%7D%7B2%7D%20%7D%20%20%20%3E%20%5Cfrac%7B20%7D%7B2%7D%20)
Result:
![\boxed{\tt \: x > 10 }](https://tex.z-dn.net/?f=%20%20%5Cboxed%7B%5Ctt%20%5C%3A%20x%20%20%3E%2010%20%7D)
For the first one...
1,15
2,30
3,20
and for the second one is the same as the first one.
EXTRA CREDIT:
Week one increases by 15, week two increases by 15 but week three decreases by 15. The total miles ran would be 15 miles
15+15=30 30-15=15 miles
The speed of the car is 40meters/hour
The page is 12 inches wide. He wants to center the photo that is 3 1/2 inches wide. So, you do 12 - 3 1/2 (3.5), which equals 8.5. Then, because the page has 2 sides (obviously), you do 8.5 ÷ 2, so your answer is 4.25 (4 1/4) :)
P.S you are not stupid :)
