The dilation factor for the question should be 1/2 as per options
So
dilated lengths are
- 2(1/2)=1in
- 4/2=2in
- 1/2=0.5in
- 5/2=2.5in
Option D
Answer:
63
Step-by-step explanation:
Follow PEMDAS, as well as the left -> right rule.
Note that PEMDAS is the order of operations in which you should solve, and =
Parenthesis
Exponents (& roots)
Multiplication
Division
Addition
Subtraction.
First, look at the problem. The problem gives you:
42 ÷ 2 x (11 - 8)
Using PEMDAS, first, solve the parenthesis:
11 - 8 = 3
Next, use the left -> right rule to solve the rest.
42 ÷ 2 x 3
(42 ÷ 2) x 3
(21) x 3 = 63
63 is your answer.

Answer:
x=3,0
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.

Let x and y be the price of the fridge and the freezer before the sale, respectively.
Since the sale offers 15% off everything, Kristianne actually paid the remaining 85%
We are given that the freezer costed 250 before the sale, i.e. y=250. Plug this value in the equation to get
We can manipulate this expression to get
