Answer:
X=6,x=2
Step-by-step explanation:
X2-8x+12
So we will have to factorise
So let's solve
X2-8x+12
X2-6x-2x+12
X(x-6)-2(x-6)
(X-2)(x-6)
X-2=0
X=2
X-6=0
X=6
X=6 or x=2

Answer:
She can send 200 messages....
Step-by-step explanation:
We have given:
Josephine is on a cell phone plan where she pays $20 a month plus $.10 per text message she does not want to spend more than $40 on her cell phone bill
The equation we get is:
20+0.10x<=40
Now solve the inequality:
20+0.10x<=40
Combine the like terms:
0.10x<= 40-20
0.10x <= 20
Divide both sides by 0.10
0.10x/0.10 <= 20/0.10
x <= 200
She can send 200 messages....
Answer:
C. 98
Step-by-step explanation:
If you add all of his previous test scores and go through the list of numbers you get C.98 as the answer. I added all of his test scores plus 98 which equals 630 divided by 7 (because if he got a 98 there would be 7 test scores) you would get 90 or an A average.
You have to do 21+8+11=40. So 40 is the answer. Hope this helps.
