5,500 days or what? I don't get it
Answer: 15/4 or 3 3/4
Explanation: You make 2 1/2 into 5/2 (improper fraction) and 1 1/2 into 3/2.
You multiply the two together (5/2 x 3/2) equaling 15/4 (improper fraction) or 3 3/4 (mixed fraction)
Answer: C & E
40% is equal to 0.4 as a decimal. As a fraction it is equal to 2/5 in simplest form.
In order to find the present you would have to multiple one of the numbers above by the initial value 84.
If you would like further explanation let me know. :)
If the formula is P = 3s, then to find side length (s) the formula will become...
s = P/3
answer D
1. The area is l * w, so just multiply 5x by 5x. Replacing x with 2.2 gets:
(5 * 2.2) * (5 * 2.2)
11 * 11
= 121
So, the area of the square when x = 2.2 centimeters is 121 sq cm.
2. The expression for this equation would be:
6(y + 4)
And using the distributive property on this to get the simplified expression, just multiply both y and 4 by 6.
6 * y + 6 * 4
6y + 24
So, your expression is 6y + 24.
3. For this one, let's make y's value 3.5 instead of 3 1/2 to make it easier to solve.
We just use the above expression to solve.
6 * 3.5 + 6 * 4
21 + 24
= 45
So, the area of the rectangle when y = 3 1/2 is 45 sq in.
4. For this last one, let's use the formula w = A/l to form an expression that will represent the width.
w = 8w + 18/2
Now, let's simplify it by dividing 8w and 18 by 2.
w = 8w/2 + 18/2
w = 4w + 9
So the expression to represent the width of the rectangle is 4w + 9.
Hope this helped!
