Answer:
Note: If this is really sixth grade math, then im a cucumber. It's way easier than MY math, and I'm in 6th grade lol :P
Another Note: Please vote me "Brainliest", I put a lot of work into this :)

11. Sahil came up with his answer so quickly because if 45 is 10% of <em>x</em>, then obviously 30% of x would be 45 times 3 and that is 135. Due to this, he quickly new that the number of people between the ages of 30 and 49 that voted is 135 people.
That's it, please heart my answer and vote me brainliest :)
Step-by-step explanation:
Do you really need this part? I didn't do it because it would take forever LOL
Answer:

Step-by-step explanation:
he is DIVIDING it among his children so the equation will have division
Answer:
p value = 0.302
Step-by-step explanation:
Given that all cars can be classified into one of four groups: the subcompact, the compact, the midsize, and the full-size. There are five cars in each group. Head injury data (in hic) for the dummies in the driver's seat are listed below.
H_0: All cars have same mean values
H_a: atleast two cars have different mean values
(Two tailed anova test)
Anova: Single Factor
SUMMARY

Subcompact 5 3444 688.8 48502.7

Since p value of 0.302 is greater than 0.05 significance level we accept null hypothesis.
p value = 0.302
This is equal to:
(8.9*4)(10^4*10^8)
pertinent rule: (a^b)(a^c)=a^(b+c)
(8.9*4)(10^12)
35.6X10^12
3.56X10^13 (and if we kept only significant figures....)
3.6X10^13
!z!=a→z=a or z=-a; z=4x+3, a=9+2x
!4x+3!=9+2x
1) 4x+3=9+2x
Solving for x:
4x+3-3-2x=9+2x-3-2x
2x=6
2x/2=6/2
x=3
Checking for extraneous solution:
!4x+3!=9+2x
x=3→!4(3)+3!=9+2(3)
!12+3!=9+6
!15!=15
15=15 Ok, then x=3 is not a extraneous solution
2) 4x+3=-(9+2x)
Solving for x:
4x+3=-9-2x
4x+3-3+2x=-9-2x-3+2x
6x=-12
6x/6=-12/6
x=-2
Checking for extraneous solution:
!4x+3!=9+2x
x=-2→!4(-2)+3!=9+2(-2)
!-8+3!=9-4
!-5!=5
5=5 Ok, then x=-2 is not a extraneous solution
Answer:
x = -2 or 3
