Answer:</h2>
<u><em> 17 + z -(-9)</em></u>
<u><em>+17 +17</em></u>
<u><em>(34) + (26)</em></u>
<u><em> z=60</em></u>
<h2>
Step-by-step explanation:</h2>
<em><u>You need to solve for Z so we need to get z by itself so take 17 and add it to both sides because whatever is on the left side of the equal sign is always what you need to add 17+ 17 then 17+(-9) you get your answers then add those two up then you get z=60.</u></em>

To solve this problem you must apply the proccedure shown below:
1. Yoy have that the <span>rectangular tank has the following dimensions:
Length=3 inches
Widht=4 inches
Height=5 inches
2. Then, its volume is:
V1=LxWxH
V1=3 inchesx4 inchesx5 inches
V=60 inches</span>³
3. The sides of the <span>solid metal cube are of 3 inches, therefore, its volume is:
V2=s</span>³
V2=(3 inches)³
V2=27 inches³
4. T<span>he volume, in cubic inches, of water that the tank can now hold is:
Vt=V1-V2
Vt=60 inches</span>³-27 inches³
Vt=33 inches³
The answer to this is 7/16 * 8= 7/2= 3.5

Answer: 127</h3>
=================================================
Explanation:
The phrasing "2/3 of 4/5 of his 2nd exam on his 3rd test" is a bit clunky in my opinion. It seems more complicated than it has to be.
The student got 80 on the second exam. 4/5 of this is (4/5)*80 = 0.8*80 = 64. Then we take 2/3 of this to get (2/3)*64 = 42.667 approximately. If we assume only whole number scores are given, then this would round to 43.
Let x be the score on the fourth exam. Since 5 points of extra credit are given, the student actually got x+5 points on this exam.
So we have these scores
- first exam = 70
- second exam = 80
- third exam = 43
- fourth exam = x+5
Adding up these scores and dividing by 4 will get us the average
(sum of scores)/(number of scores) = average
(70+80+43+x+5)/4 = 80
(x+198)/4 = 80
x+198 = 4*80
x+198 = 320
x = 320 - 198
x = 122
So the student got a score of x+5 = 122+5 = 127 on the fourth exam.
The answer is C because there are arrow at the end of each line meaning it goes on forever
