Answer:
p=-7
Step-by-step explanation:
-11+10(p+10)=4-5(2p+11)
Firstly, expand the bracket
-11+10p+100=4-10p-55
Next, you collect like terms
10p+10p=4-55-100+11
20p=-140
Divide through by the coefficient of p
20p/20=-140/20
p=-7
0-5 because 25th percentile can also be known as the 1st quartile or the first 25% of it. so since the medium is 8 then it would be the first interval or 0-5.
if i am wrong please let me know.
Answer:
B = 70
Step-by-step explanation:
The sum of the angles of a triangle add to 180 degrees
A + B + C = 180
40 + 2x-30 + x+20 = 180
Combine like terms
3x + 30 = 180
Subtract 30 from each side
3x+30-30 = 180-30
3x = 150
Divide by 3
3x/3 =150/3
x = 50
We want to find angle B
B = 2x-30
=2(50) - 30
= 100 - 30
= 70

Answer:
x = 25/6
Step-by-step explanation:
1. Make an Equation
8x - 14 = 2x + 11
2. Subtract 8x - 2x
6x - 14 = 11
3. Add 14 + 11
6x = 25
4. Divide 25 by 6
x = 25/6
