Step-by-step explanation:
4d^2-49=2
4d^2=49+2
4d^2=51
d^2=51/2
d= square root 51/2
To convert from feet to inches, you will multiply or divide by 12. To convert from miles to feet, you will multiply of divide by 5280
2. 5*12= 60in
3. 5*5280= 26,400ft
4.240/12= 20ft
5. 100*3= 300ft
6. 10*12= 120in
7. 150/12= 12.5ft or 12ft 6in
8.7*3= 21ft+2ft= 23ft
9. 10*5280= 52,800ft
Answer:
F/7 +46=n
Step-by-step explanation:
(WARNING IDK IF THIS IS THE CORRECT WAY TO SOLVE) Start with the equation itself F-7(n-46). You’re first step is to simplify the equation by distributing -7 to (n-46). So multiple n by -7 and multiply -46 by -7. After that you’re equation should look like f-7n+322. This is when you can start trying to solve for n. You want n on the other side of the equal sign so you’re going to add -7n to the one side of the equal sign. F+322=7n. Now to get n by itself divide 7 to both sides of the equation. This will give you F/7+6=n.
