Answer:
Step-by-step explanation:
I think you need to multiply 4 1/2x3 and 2 1/2x4 and then when you get the answers for both you add them together hopefully this works
The solution to the linear equation:
8h + 5 - 3h = 8h - 4
is h = 3.
<h3>
How to solve the linear equation?</h3>
Here we have the linear equation:
8h + 5 - 3h = 8h - 4
To solve it, we need to move all the terms with h to the left side of the equation and the terms without x to the right side:
8h - 3h -8h = -4 - 5
-3h = -9
Now we can divide both sides by -3 to get:
h = -9/3 = 3
We conclude that the solution to the linear equation is h = 3.

To solve this, we need to set up two different equations, then use them to find what we are looking for.
First, we need to change the words in the problem into variables and numbers. "The length of a rectangle is 3mm less than four times the width." This translates into: L=4W-3
Now, we are given the area and are told to solve for the dimensions (meaning the height and width. We need to use the area equation for a rectangle to finish the problem. A=L x W
Substitute the equation we created for the length into the area equation and we can solve for the width.
A= L x W --> 1387=(4W-3) x W --> 1387=4W^2-3W --> 0=4W^2-3W-1387
0=4(W-19)(W+18.25)
So our width either equals 19 or -18.25, and since a distance can't really be negative, our width is 19mm. Now we can use this to solve for length.
L=4W-3 --> L=4(19)-3 --> L=76-3 --> L=73
Our length is 73 mm.
Check: We can check this answer by multiplying the two numbers to see if they provide the area given in the problem. A=73x19=1387mm^2
Based on the given figure above which is about the favorite communication method, we can see that the most favorite is cell phone next and followed by e-mail, then the third one is cell phone call, then instant message, and the least favorite would be landline call. So based on the results, the third most favorite communication method would be cell phone call. The answer is option B.
