A computer moniter is solid by the diagonal length of the screen a computer monitor has a 15 inch screen the screen has a width
n200080 [17]
For this problem, you would use the Pythagorean Theorem (a^2 + b^2 = c^2)

A and B are the length and width of the triangle. The triangle is created by the diagonal line splitting the computer screen. C is the hypotenuse, which is the diagonal line, and will always be the longest side of the triangle. 

When we plug in the numbers into the formula, we would get this:

13^2 + b^2 = 15^2

B is the unknown variable in which we are trying to find.
First, you square 13 and 15:

169 + b^2 = 225

Then, subtract 169 from both sides:

b^2 = 56

Finally, find the square root of both sides:

b = 7.483314774

Simplify to the nearest tenth, and the answer is 7.5<span />

Hey.. I know you haven’t been able to find much help, but if you are still struggling this might help.

Try to set it up as an equation for example 25x +25=10x +15 and rewrite it in standard form and see if that helps

Answer:

Part A: B) 3

Part B: $40

4. -1

7. 5x + 6y

8. Part A: y = 20x

8. Part B: $300

9. e > 12000 pounds

Step-by-step explanation:

Part A: x = 5t + 5

20 = 5t +5

15 = 5t

t = 3

Part B: x = 5t + 5

x = 5(7) + 5

x = 35 +5

x = 40

4. 24 - 5^2

24 - (5*5)

24 - 25 = -1

7. 2x + 4y + 5 + 2y - 5 + 3x

2x + 3x = 5x

4y + 2y = 6y

5 + (-5) = 0

5x + 6y

8. Part A:

Total = y

Lawns = x

Amount = $20

so y = 20x

8. Part B:

y = 20x

y = 20(15)

y = 300

9. The elephant weighs more than 12000 pounds

Elephant = e

More than =  >

Pounds = 12000

e > 12000 pounds
