Answer:
t=20n
Step-by-step explanation:
The answer would be t=20n or something similar because 20n stands for $20 per lawn, which equals t, the total.
Hello again! So we will be using the pythagorean theorem (

) to solve for the bottom leg of the triangles. After we do that, we'll subtract the value of the legs from 31, and that'll be x.
Plug in 17 and z (or any variable that isn't x) into the leg variable and 19 into the hypotenuse variable, and from there we can solve.

Solve the exponents to get

Subtract 289 on each side to get

Lastly, square root each side of the equation and your answer should be

(To get more accurate answers, you shouldn't round until the end of the problem)
Nextly, we will need to subtract

from 31. And since there are 2 triangles, you'll need to multiply

by 2.
In short, x = 14.0
If the first one is a = 180 - b, and not 180 - 6, then that is correct.
Also, 360 = 2a + 2b is correct
Answer:
1486.67 or 1487.
Step-by-step explanation:
Find the average of those three things. Add 2,340 plus 470 plus 1650. You get 4460. Since you have three costs, divided 4460 by 3, which is 1486.6 repeating. Round to the nearest hundredth which is 1486.67. Hope this helps!

All you have to do is use the conversion rate for pounds to kilograms. Have a nice day :)
