Answer:
x=10
Step-by-step explanation:
The mean is all the numbers added up, and divided by the number of terms, so
14+10+17+19+x/5
And, we know that the expression above must equal 14
14+10+17+19+x/5=14
Solve, first by multiplying by 5 on both sides
14+10+17+19+x=70
Add on the left side
60+x=70
Subtract 60 from both sides
x=10
Hope this helps! :)
Answer:they are supplementary ,adjacent and linear

Answer:
(2, 8)
Step-by-step explanation:
Given the system of equation
3x+2y=22 ... *4
-4x+3y=16 .... *3
Using the elimination method
12x + 8y = 88
-12x + 9y = 48
Add
8y + 9y = 88+48
17y = 136
y = 136/17
y = 8
Recall that
3x+2y=22
3x+2(8)=22
3x + 16 = 22
3x = 22-16
3x = 6
x = 6/3
x = 2
Hence the required solution (x, y) is (2, 8)
1.34 inches is 3.35%
2.54 inches is 6.35%.
Take the numbers and divide by 40!
