First, you have to find x
KG and HK are equal
3x=x+8
Solve, and you get 4=x
plug that in to x+3
JL=7
LG is twice as long as JL
7*2=14
JL is 14
make sure to rate brainliest if it helped!!
Answer:
a. 7
Step-by-step explanation:
So a triangle a two sides that will always sum up to be greater than the third side.
Meaning:
a + b > c
a + c > b
b + c > a
So here, we're given a and b:
8 + 5 > c
8 + c > 5
5 + c > 8
Plug in the values:
13 > 7
15 > 5
12 > 8
These are all true, so it's probably 7.
13 > 2
10 > 5
7 > 8 This one is not true, so not 2.
13 > 13 This is not true, so not 13.
If not 13, we can't go any higher and so it can't be 15.
Answer: There are 500 ninth grade students at Richbartville high school.
Step-by-step explanation:
Let be "x" the number of ninth grade students that are at Richbartville high school.
You know that the number of ninth grade students take algebra is 450 and this amount represents the 90% of the the ninth grade students at Richbartville high school.
Knowing this, you can set up the following proportion:
The final step is to solve for "x" in order to find its value. This is:
Therefore, there are 500 ninth grade students at Richbartville high school.
