Answer: 

Step-by-step explanation:

Subtitute y in the first equation.

Now replace x in either equation to find y.

 
        
                    
             
        
        
        
Answer:
The second option, 1,008 cm²
Step-by-step explanation:
    This shape has 5 sides to solve for with reguards to surface area.
    Let us solve for them all.
[1 & 2 - the triangles]
12 * 9 = 108 cm²
-> I am not going to divide since we have 2 congruent triangles
[3 - the bottom side]
25 * 12 = 300 cm²
[4 - the side facing away]
25 * 9 = 225 cm²
[5 - the side facing up]
25 * 15 = 375 cm²
    Now we will add them together for the total.
108 + 300 + 225 + 375 = 1,008 cm²
              The surface area for the triangular prism shown is 1,008 cm².
 
        
                    
             
        
        
        
Jacqueline is incorrect. 
To find how much trash you can clean in 4 days if you already know how much trash you can clean in one day, multiply 1 2/3 (how much you can clean in one day) by 4. 
Another way to write 1 and 2/3 miles is 5/3 (converting a mixed number to a single fraction). Then, 5/3 x 4 = 20/3. (To multiply fractions, just multiply across, leaving 5 x 4 in the numerator and 4 x 1 in the denominator.)
Jacqueline said you would be able to clean 19/3 miles but you can actually clean 20/3.
