Answer:
1. -3
2. -12
3. 20
4. -15
5. 6
6. -15w+5
7. 10
8. C<-26
9.p> -40
10. P> 16
Step-by-step explanation:
~ -9p -17 = 10
-9p = 27
P = -3
~ x/4 -5 = -8
x/4 = -3
x = -12
~ p/5 +6 =10
p/5 = 4
p = 20
~ -2(m-30) =-6m
-2m+60=-6m
4m = -60
m = -15
~ 3n +2=8+2n
n = 6
Answer:
5/8+1/2=9/8 or 1 1/8
Step-by-step explanation:
1/2 x 4 (top and bottom)= 4/8
5/8 + 4/8 = 9/8
Only like sedans: 25- 15 = 10
Only like hatchbacks: 40-15 = 25
Like both: 15
Like none of them: 100-10-25-15 = 50
Dislike sedans: 100 - 10-15 = 75
Dislike hatchbacks: 100-25-15 = 60
So dislikes: sedans>hatchbacks
Answer:
If we have a set of N elements:
{x₁, x₂, ..., xₙ}
The mean value (also called the average value) Is calculated as:
Average = (x₁ + x₂ + ... + xₙ)/n
So if x is the average of 13, -16 and 6 ( a total of 3 values)
x will be equal to:
x = (13 + (-16) + 6)/3 = (19 - 16)/3 = 3/3 = 1
x = 1
And we know that:
y = ∛8
Remember that:
2*2 = 4
and
4*2 = 8
then
2*2*2 = 2^3 = 8
then ∛8 = 2.
So we have:
y = ∛8 = 2
Now we can replace these values in the equation:
x^2 + y^3
replacing:
x = 1
y = 2
we get:
1^2 + 2^3 = 1 + 8 = 9
