Since 12.3 is kind of a margin that you have to fit by, the total weight of the golf clubs must be lesser than or equal to 12.3. So, that's your expression:
![0.8x \leq 12.3](https://tex.z-dn.net/?f=0.8x%20%5Cleq%2012.3)
x represents the number of golf clubs you have.
If this doesn't make sense, feel free tell me!

To find the original length you must take away the add-ons. To do so we know that they added 7 and A= l*l (or l squared). They added the 7 to the length so multiply 7*7 (49) subtract your answer from 169 (120) and that's your new area. To find the original length divide by 4 (I believe) and get 30m2
Part A:
Given that <span>Starlight tree farms sells Douglas Firs and Noble First.
Let </span>n be the number of Noble Fir trees sold, then<span> if they sold 139 more Douglas First than Noble Firs, this means that the number of Douglas First trees sold is n + 139.
Given that the total number of trees sold was 377, then we have, n + n + 139 = 377, which means that 2n + 139 = 377
Therefore, the equation that could be used to solve for n, the number of Noble Fir trees sold is 2n + 139 = 377.
Part B:
</span><span>Given that you are driving 55 miles per hour and you must drive a total of 440 miles. If you already driven 275 miles, then, the equation representing the number of hours, h, it will take to reach your destination is given by 55h + 275 = 440.
Subtracting 275 from both sides of the equation gives:
</span>
![55h+275-275=440-275 \\ \\ \Rightarrow55h=165](https://tex.z-dn.net/?f=55h%2B275-275%3D440-275%20%5C%5C%20%20%5C%5C%20%5CRightarrow55h%3D165)
<span>
Dividing both sides by 55 gives:
</span>
![\frac{55h}{55} = \frac{165}{55} \\ \\ \Rightarrow h=3](https://tex.z-dn.net/?f=%20%5Cfrac%7B55h%7D%7B55%7D%20%3D%20%5Cfrac%7B165%7D%7B55%7D%20%20%5C%5C%20%20%5C%5C%20%5CRightarrow%20h%3D3)
<span>
Therefore, the time it will take you to reach your destination is 3 hours.</span>
