20 is the answer for 4 times 5
45 adult tickets were sold.
adult tickets = a
childrens tickets = b
a + b = 65
6a + 3.5b = 340
Subtract a from the equation on top to get b = 65 - a
Substitute into the second equation 6a + 3.5(65 - a) = 340
Simplify to make 6a + 227.5 - 3.5a = 340
6a - 3.5a = 340 - 227.5
Combine like terms so that 2.5a = 112.5
Divide both sides by 2.5 to isolate the variable a
Your final answer is a = 45
Answer:
Step-by-step explanation:
The area of the floor A = Length * Width
Given
A = 200 square meters
If the length of the floor is 32 m longed than it’s width then;
L = 32+W
A = LW
200 = (32+W)W
200 = 32W + W²
W²+32W-200 = 0
W = -32±√32²+800/2
W = -32±42.71/2
W = -32+42.71/2
W = 10.71/2
W = 5.35 m
L = 32+5.35
L = 37.35m
Hence the dimension is 5.35ft by 37.35m
Answer:
6 minutes
Step-by-step explanation:
- Set up the proportion as these two fractions equal to each other
9/3 = 18/x
2. Cross multiply so that 9*x=18*3
3. 9x=54, so now you divide 54 by 9
and this will give you
4. x= 6, so it will take 6 minutes to fill
up the 18 gallon pool
Hope this helped!
Answer:
The probability is 1/20 or 5 %
Step-by-step explanation:
1). First, how many shirts there are in the drawer?
9 + 6 + 5 = 20 shirts
2). Since we are choosing 1 shirt out of 20, then the probability will be 1/20 or 5%.
