Answer:
16
Step-by-step explanation:
To solve plugin -3 for n

Then, solve using PEMDAS. First, do exponents

Next, add

So, 16 is the final answer.
Z varies inversely as w ⇒ z*w=k
when z=7 and w=8 ⇒ 7*8=56=k
when w=14 ⇒ z*14=56
⇒z=56/14
⇒ z=4
Answer:
98in^2
98 inches squared
Step-by-step explanation:
24.5=1 triangle
x=4 triangles
x=24.5*4
x=98 in^2
9x + 4 ≤ 58
=> 9x ≤ 58 - 4
=> 9x ≤ 54
=> x ≤ 54/9
=> x ≤ 6
______________
1/6x − 2 > 3
=> 1/6x > 3 + 2
=> 1/6x > 5
=> x > 5×6
=> x > 30
Answer:
- b = 15
- c = 51
- c = 100
- b = 25.75
Step-by-step explanation:
Using the Pythagoras theorem equation:

Where 'c' is the hypotenuse and 'b' and 'a' the sides of the right triangle.
1) Here c = 17, a = 8 and b = ?
Then, using the above equation we can find the side b.


2) Here a = 24, b = 45 and c = ?

3) Here a = 28, b = 96 and c = ?
4) Here a = 17, b = ? and c = 28

Just in the 4 case x is an altitude.
I hope it helps you!
