Answer:

n=5

Step-by-step explanation:

7n-4=31

The goal is to get the variable alone. Start by adding 4 to both sides.

7n=35

To separate the n further we divide both sides by 7.

n=5

We can actually plug that value in to check our answer.

7×5-4   this value does equal 31, so we know it is correct.

Which is bigger negative 4 or negative 5
VladimirAG [237]

Need help with math. I will give brainliest!!!!!!
Mice21 [21]

Answer:

~~

Step-by-step explanation:

Ok so first 2.4 will have to be changed to 24 which means we multiplied it by ten making it 24/10 since it is tan it is opposite side/ adjacent side so your one of your legs will be 24 and one will be 10. Now we just plug that into the Pythagorean Theorem to find the hypotenuse and we get 26. The area is 24b10/2=120 the area is 120.

Leg a= 24

Leg b= 10

Hypotenuse=26

Area=120
