Answer:
D. (1.6 + 3) × (4 − 2) ÷ 2
Step-by-step explanation:
The order of operations requires that multiplication and division be done in order of appearance, left to right, before addition and subtraction. Operations in parentheses take priority.
To get 4.6, you need to add 3 to 1.6. The various forms of 3×4-2÷2 all give 12-1 = 11, not 3.
The grouping that gets it right is ...
(1.6 + 3) × (4 − 2) ÷ 2
= 4.6×2÷2
= 9.2÷2
= 4.6
First of all, the shaded part is under the line, so it is a smaller than, so we can eliminate D
next, look at the vertex, it is at (5,5), which means when x=5, whatever is inside the absolute symbol has a value of zero, and y will be 5
so the answer is A
Answer:
Step-by-step explanation:
We know that 
And we want to find 
So, we will simply substitute <em>2w</em> for <em>z</em>. This yields:
Distribute. Therefore:
