-8x+4=36
-4 -4
-8x=32
divde be -8 on both sides
x=-4
Answer:
14.32
Step-by-step explanation:
We can find the distance using the distance formula:
We then substitute (-2,8) as
and (11,2) as
.
Answer:
B. 2x-y = 8
Step-by-step explanation:
First, plug in the points (5,2) into the equation. 5 being x and 2 being y.
Then 2x-y = 8
2 (5) - (2) = 8
10 - 2 = 8
8 = 8
Answer:
Kameron is 50 years old.
Step-by-step explanation:
We can make equations and start filling in what we already know, assuming
is Niko's age,
is Lila's age,
is Amber's age, and
is Kamerons age.
Our first equation:
n = 3L
We know that Niko is 45, so
45 = 3L
Divide both sides by 3:
L = 15
So, Lila is 15 years old.
Another equation:
n = L + 3a
We already know Niko and Lila's age:
45 = 15 + 3a
Subtract 15 from both sides:
30 = 3a
Divide both sides by 3:
a = 10
So Amber is 10 years old.
Another equation:
k = 2(a + L)
We know Amber and Lila's age:
k = 2(10 + 15)
k = 2(25)
k = 50
So Kameron is 50 years old.
Hope this helped!
