Answer:
12
Step-by-step explanation:
(1×3)+(1×3)+(1×3)+(1×3)
3+3+3+3
12 apples
About 40 swimmers maybe more
L = 15m = 1500cm
b= 30cm
h= 4m= 400cm
So, total volume of the wall= l×b×h
= 1500×30×400= 1,80,00,000 cm^3
Now, volume of one brick= 22×12.5×7.5= 2062.5 cm^3
Volume of wall containing only bricks= total volume of the wall - volume of wall containing mortar
= 1,80,00,000 - (1,80,00,000 × 1/12)
= 1,65,00,000 cm^3
So, no. of bricks = volume of wall containing bricks ÷ volume of one brick
= 1,65,00,000 ÷ 2062.5
= 8000 bricks.

Step-by-step explanation:
42,300
1.
we distribute then move placeholders to get
2x+4=4x-6+1
9=x
one solution
2. distribute
4x+12=3x+17
x=5
one solution
3. distribute and combine like terms
5x+4=5x-10+7
4=-3
false
no solution
4. distribute
2+10x=10x-5
2=-5
false
no solution
5. distribute
-18+15x=12x-18+3x
x=x
true
infinite solutions
