Answer:
$26.31
Step-by-step explanation:
Since 3 is half of 6, 3 pairs of shoes would cost half the price.
So...
52.62/2=$26.31
Answer:
A. Acute
B. 80 degrees
Step-by-step explanation:
Answer:
Step-by-step explanation:
We have the recursive formula of a sequence:
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!
