P=number of pages
we have to divide the number of photos by p
algebreaic expression represents the number of photosn on each page=60/p
60/p
Step 1: subtract x from -3. New equation should be y=-3-x.
Step 2: plug that equation into top equation. Should be 5x + 2(-3-x) = 9.
Step 3: use distribitive properties on 2(-3-x). New equation is 5x - 6 - 2x = 9.
Step 4: combine like terms. New equation 3x - 6 = 9.
Step 5: work it out. Divide 3x and 9 by 3. New equation is x - 6 = 3. Add 6 to -6 and 9. Final eqaution is x = 9.
Step 6: swap 9 for x in second equation. New equation is 9 + y = -3
Step 7: subtract 9 from 9 and -3. New equation is y = -12

teacher has 0.4 L of sea water , it means 0.4*1000 ml = 400 ml of sea water , she has.
Now every student has 5 ml spoon with them and there are a total of 20 students.
The teacher has asked every student to put 2 spoons of seawater into their container .
Now 1 spoon = 5ml
2 spoon = 10 ml
22 students are there it means
there are 44 spoons.
44 spoons = 44* 5 ml = 220 ml
It means Student put 220 ml seawater in total
And Teacher had 400 ml.
Now , Teacher is left with = 400 - 220 = 180 ml
The perimeter of ADC is 9.5 cm.
