For part A add up all your students then add up all your students that like bike riding and skating (80+90) divide that by the total number of students who took the survey
For Part be put 20+40 over the toatl number of student then simplify
Answer:
It would be 150 I believe.
Step-by-step explanation:
Hope this helps and good luck!
To simplify, we can use the FOIL method. That stands for first, outer, inner, last. What we do is take two factors at a time and multiply the first terms by each other, the outer terms together, etc.
Let's start with (2x-1) and (x+5)
First: 2x * x = 2x^2
Outer: 2x * 5 = 10x
Inner: -1 * x = -x
Last: -1 * 5 = -5
2x^2 + 9x - 5
Now FOIL this result with (3x - 2)
6x^3 - 4x^2 + 27x^2 - 18x - 15x + 10
Simplify:
6x^3 - 23x^2 - 33x + 10
Answer:
couldnt draw sorry but heres the answers for a
Step-by-step explanation:
for x = -2
x+y= 6
-2+8=6
so y=8
for x=-1 do the same and y= 7
for x =0 y=6
for x=1 y=5
for x=2 y=4
for x=3 y=3
Answer : 7 feet
In triangle NQL, point S is the centroid, NS = (x + 10) feet, and SR = (x + 3) feet.
the diagram is attached below
Centroid divides the angle bisector into parts
NS = 2/3 of NR and SR = 1/3 of NR
So NS is 2 times of SR
NS = 2 SR
NS = (x + 10) feet, and SR = (x + 3) feet.
(x+10) =2 (x+3)
x + 10 = 2x + 6 ( subtract 2x and 10 on both sides)
-x = -4
So x=4
SR = x + 3 = 4 + 3 = 7
SR = 7 feet
