Answer: 17 inches
Explanation: so we have a triangle with the two side lengths 8 and 15 and we’re trying to find the hypotenuse. so using the pythagorean theorem, we have 8^2 + 15^2 = c^2. when we solve we get 64 + 225 = c^2, which is 289 = c^2. next, we find the square root of both sides and c = 17 inches.
hope this helped!
Let c = # of children who bought a ticket // Let a = # of adults who bought a ticket
Since the theater company charges $8.50 for all age groups, it isn't necessary to have two different variables. The expressions that you could use are:
8.5(a + c)
8.5a + 8.5c
They both equate to the same thing, just two different ways of writing it. I hope this helps!
Answer:
its the last one
Step-by-step explanation:
the sign flips when you divide by a negative
Step-by-step explanation:
let jon age be x
dad age is 2 of x i.e 2x
grandpa age is 7 + 3(x)
The sum of jon dad and grandpa age is 145 i.e
x + 2x + (7+3x) = 145
3x +. 7 + 3x = 145
6x = 145- 7
6x = 138
divide both sides by 6
x = 23
jon age is 23
while
grandpa age is
7 + 3(x)
7 + 3(23)
7 + 69
76.
It's directly proportional, so
m=kw
