Answer:
p = all real numbers
Step-by-step explanation:
First distribute the numbers to the expressions inside the parenthesis
-11 + 10(p + 1) = -16 + 5(2p + 3)
-11 + 10p + 10 = -16 + 10p + 15
Then, add up the like terms
10p - 1 = 10p - 1
Add one to both sides
10p - 1 = 10p - 1
+ 1 + 1
10p = 10p
Divide both sides by 10
10p/10 = 10p/10
p = p
This means that no matter what you plug in for p, it will always be true.
Answer:
x=2 x=-4
Step-by-step explanation:
x^2 +2x-8=0
Factor
What numbers multiply to -8 and add to 2
-2*4 = -8
-2+4 =2
(x-2) (x+4) =0
Using the zero product property
x-2 =0 x+4 =0
x-2+2=0+2 x+4-4=0-4
x=2 x=-4
Interpretation: In triangle ABC, A is the right angle, angle B measures 46 degrees. Find the measure of angle C.
Assuming correct interpretation,
We know there are 180 degrees in a triangle.
A right angle is 90 degrees. So together, A and B measure 90 + 46 = 136 degrees. This means the last angle must be 180 - 136 = 44 degrees
Answer:
5 packages
Step-by-step explanation:
One package of blackberries cost $3
Let x represent the number of packages that will cost $15
1 = $3
x= $15
3x= 15
Divide both sides by the coefficient of x which is 3
3x= 15/3
x= 5
Hence 5 packages of blackberries will cost $15
Answer:
Perimeter = 9x + 12x + 15x
Perimeter = 36x (simplified)
