Answer: 6
Step-by-step explanation:
7 - 3 = 4
3 - 4 = 0
0 - 6 = -6
Step-by-step explanation:
![- 10n + 24 + 30n = - 36](https://tex.z-dn.net/?f=%20-%2010n%20%2B%2024%20%2B%2030n%20%3D%20%20-%2036)
Collect like terms and simplify
[tex] -10n+30n=-36-24 \\ 20n = -60 [/tex]
Divide both sides of the equation by 20
[tex] 20n/20 = -60/20 \\ n=-3 [/tex]
If x is the hypotenuse then
hyp^2 = 4^2 + 5^2
hyp^2 = 41
hypotenuse =
<span>
<span>
<span>
6.403124
</span></span></span>
if x is a leg then
leg^2 = 5^2 - 4^2
leg^2 = 25 - 16
leg^2 = 9
leg =3
Answer:
x = 28
Step-by-step explanation:
7(8 - x) = -5x
56 - 7x = -5x Distribute 7 to the parenthesis
56 = 2x Add -7x to both sides
28 = x Divide 2 to both sides
