Answer:
570 adults and 215 children
Step-by-step explanation:
did this assignment and got it right
5a + 2c = 3280 where a is adults and c is children
subtraction eliminates c, find a
3a + 0 = 1710
a = 1710/3
a = 570 adult and then you have to subtract 785-570= 215 children
4 times 3 is 12
2 times 6 is 12
Answer:
The answer is A. -5
Step-by-step explanation:
Write out the equation:
-3 + c = -8 Add 3 on both sides to isolate the varible on one side
c = -5 -8 plus 3 is -5
You must isolate the variable in order to solve equations with variables.
Isolating variable is basically when you divide, multiply, add, or subtract to put a variable on <u><em>ONLY </em></u>one side of the equation.

We are required to find the percent of an acres is this lot
The percent of acres of the lot is 27.55%
Area of an acre = 4840 square yards
Area of the lot = Length × width
= 40 feet × 100 feet
= 4000 square feet
<em>convert feet to yards</em>
1 foot = 0.333333
4000 square feet = 1333.333 square yards
Therefore,
Area of the lot = 1333.333 square yards
percent of an acres is this lot = 1333.333 / 4840 × 100
= 0.2754820247933 × 100
= 27.548202479338
Approximately,
27.55%
Therefore,
The percent of acres of the lot is 27.55%
