Answer:
n = 17
Step-by-step explanation:
+(-6) is the same thing as n - 6 = 11 to take out the + sign in order to avoid confusion. Add 6 on both sides to get your n value which is 17.
Answer:
Step-by-step explanation:
here you go mate
step 1
n +-6 = 11 equation/Question
step 2
n +-6 = 11 add 6 to each side
n-6(+6)=11(+6)
answer
n=17
Alicia, Quentin, and Rosalyn are siblings. Alicia is the oldest sibling. Quentin is four years younger than Alicia. Rosalyn is two years older than Quentin. The sum of the siblings’ ages, in years, is 48. How old is Alicia?
Answer:
Alicia is 18years
Quentin is 14years
Rosalyn is 16years
Step-by-step explanation:
Let the age of Alicia be x
Let the age of Quentin be y
Let the age of Rosalyn be z
If the sum of the siblings’ ages, in years, is 48 then;
x+y+z = 48.... 1
If Rosalyn is two years older than Quentin then;
z =y+2 ..... 2
Also if Quentin is four years younger than Alicia then;
y = x-4 ... 3
From 3:
x = y+4 ... 4
Substitute 2 and 4 into 1 to have:
y+4+y+y+2 = 48
3y + 6= 48
3y = 48-6
3y= 42
y = 14
Since x= y+4
x = 14+4
x = 18
Since z = y+2
z = 14+2
z = 16year
This means that;
Alicia is 18years
Quentin is 14years
Rosalyn is 16years

In the diagram if AE = AB, find the area shaded.
Answer:
Area shaded = 60 [tex]cm^{2}[/tex].
Step-by-step explanation:
From the given diagram,
Area shaded = Area of the trapezoid EBCD
Given that: AE = [tex]\frac{1}{3}[/tex]AB
= [tex]\frac{1}{3}[/tex] x 12 (∵ AB = CD = 12 cm)
= 4 cm
AE = 4 cm,
Thus,
EB = (12 - 4) cm
= 8 cm
EB = 8 cm
Area shaded = [tex]\frac{1}{2}[/tex] (EB + CD) x AD
= [tex]\frac{1}{2}[/tex] (8 + 12) x 6
= (20) x 3
= 60
Area shaded = 60 [tex]cm^{2}[/tex]
Factorise x² - 9x + 20
Step-by-step explanation:
Given
x² - 9x + 20
= x² - ( 4 + 5) x + 20
= x² - 4x - 5x + 20
= x ( x - 4) - 5 ( x - 4)
= (x - 4)(x - 5)
Hope it will help you :)

Step-by-step explanation:
i tried
Answer:
[tex]4^{6}[/tex]
Step-by-step explanation:
4 x 4 x 4 x 4 x 4 x 4 it's really just counting how many 4's there are. In this case there are 6 and the number being repeated 6 times is 4 so we only put it as [tex]4^{6}[/tex]. I know I'm late just wanted to answer :'D

An asteroid is 10^{8} miles away from earth, and it is traveling at a speed of 10^{5} miles per day.
How many days will it take the comet to reach earth?
Answer:
It will take 10^3 days for the comet to reach earth.
Step-by-step explanation:
10^8 = 100,000,000
10^5 = 100,000
100,000,000/100,000 = 1,000
1,000 is equal to 10^3
