Answer:
A. 41.6
B. 1
Step-by-step explanation:
For A you add them all up and divide by the number of terms. For this i got 832/20 which is 41.6
I think most schools define passing as getting a 70% or above and so the answer is 1
Answer:
Z=20 Degrees
Step-by-step explanation:
We know that all of the angles of a triangle add up to 180, so:
65+55+ Angle A = 180
Simplify:
120+ Angle A = 180
Subtract 120 from both sides:
Angle A = 60
If you look at the bottom you can see that the 15 turns into 5, meaning it is being divided by 3, so:
60/3=20
Z=20 Degrees
Answer:
![(x-5)(x+4)](https://tex.z-dn.net/?f=%28x-5%29%28x%2B4%29)
Step-by-step explanation:
To factor the equation, break it into two binomials which multiply to make the equation. To write these binomials (x+a)(x+b), find factors which multiply to -20 and add to -1 for a and b.
20: 1, 2, 4, 5, 10, 20
-5+4 = -1
![x^2-x-20 = (x-5)(x+4)](https://tex.z-dn.net/?f=x%5E2-x-20%20%3D%20%28x-5%29%28x%2B4%29)
Answer:
The answer is D
Step-by-step explanation:
Because you multiply everything by 2
Carl present age is 10 years while Dennis present age is 19 years.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Let x represent Carl present age and y represent Dennis present age, hence:
x + y = 29 (1)
Also:
After 6 years:
x + 6 = y - 3 (2)
From both equations:
x = 10, y = 19
Carl present age is 10 years while Dennis present age is 19 years.
