Answer:
For covering 
unit area of the entire playground, the amount of sand required is equal to volume of 
buckets of sand.
Step-by-step explanation:
Given -
volume of sand in bucket is able to cover 
area of the entire playground
Thus,
For covering unit area of the entire playground, the amount of sand required is equal to of the total volume of sand in bucket
For covering unit area of the entire playground, the amount of sand required is equal to
For covering unit area of the entire playground, the amount of sand required is equal to volume of buckets of sand.
Answer:
Step-by-step explanation:
1) Least common denominator of 4 and 2 is 4
To eliminate the fraction, each term should be multiplied by 4
ANS:option c
2) Mercury level of water 'y' years = Initial measure +rate of increase 'y' years
0.05 +0.1y = 0.12+0.06y
Ans : Option c
3) 4b +6 = 2 - b + 4
Add 'b' to both sides
4b + b + 6 = 2 + 4
5b + 6 = 6
Subtract 6 from both sides
5b = 6 - 6
5b = 0
b = 0
Ans : Option b
4) Maximum decimal places in this equation is 2. So, to eliminate decimal places, The equation should be multiplied by 100
Ans: option d
5) y +6 = -3y + 26
Add 3y to both the sides
y + 6 + 3y = 26
y + 3y + 6 = 26
4y + 6 = 26
Subtract 6 from both sides
4y = 26-6
4y = 20
Divide bothe sides by 4
y = 20/4
y = 5
Ans: option c
6) '2x' is subtracted from both side of the equation.
Ans: option a - subtraction property of equality

Answer: 3
Step-by-step explanation:
the statement given us:
7a-5b+4
a= 2
b= 3
so we have:
7*(2)-5*(3)+4
14-15+4 = 3
the answer is 3
Hopefully I’m not too late, but here’s how I solved it. Basically, replace F with 68. Subtract 32 from both sides so your equation becomes 9/5C=36. Divide both sides by 9/5 so C is left but itself (C=36/1.8). The answer should come out to 20. If you want to check my answer, plug 20 into the equation. Multiply 20x9/5 which equals 36. Add 36 and 32 together to get 68. Hope this helps
