Answer:
A= 18
Step-by-step explanation:
To find the height, find the blocks inside the shape that is completely attached (they have to be in a straight vertical line). In this case, you can see that three vertical blocks in the middle of the shape is completely attached. That means your height is 3.
To find the width, look at the how many horizontal boxes make up the top. 6 block inside the shape corispond with 6 blocks on top of the shape, so the width is six.
Multiply 6 by 3 to get 18.
A percentage is a way to describe a part of a whole. The regular selling price of the computer notebook will be $937.5.
<h3>What are Percentages?</h3>
A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Let the selling price of the computer notebook be represented by x.
Now, if Sara buys the computer this week, the selling price of the computer will be (100%-16%)x = 0.84x.
Also, the saving she made by buying this week will be $150, therefore, we can write,
x-0.84x = $150
0.16x = $150
x = 937.5
Hence, the regular selling price of the computer notebook will be $937.5.

Step-by-step explanation:
<u>Expression on the board :</u>
<u>Expression by the student </u>:
<em><u> Expression 1 </u></em>:
The expression 1 is equivalent to the expression on the board. Because the coefficients of x and y are same on both.
<em><u>Expression 2 :</u></em>
<em><u /></em>
<em><u /></em>
The expression 2 is also equivalent to the expression on the board. Because the coefficients of x and y are the same.
