Answer:
(1, 6 )
Step-by-step explanation:
5x + 2y = 17 → (1)
4x + y = 10 → (2)
Multiplying (2) by - 2 and adding to (1) will eliminate the y- term
- 8x - 2y = - 20 → (3)
Add (1) and (3) term by term to eliminate y
- 3x + 0 = - 3
- 3x = - 3 ( divide both sides by - 3 )
x = 1
Substitute x = 1 into either of the 2 equations and solve for x
Substituting into (1)
5(1) + 2y = 17
5 + 2y = 17 ( subtract 5 from both sides )
2y = 12 ( divide both sides by 2 )
y = 6
solution is (1, 6 )
For the set B= { 3, 5, 7, ,9 , 12, 17, } determine n(B)
n is asking for the count of numbers in the set.
Set B has 6 numbers.
n(B) = 6
If you add the standard deviation to the average, it is 14.84. Because Marcus's score was lower than that, he will not receive a certificate.
I think this should be right for the reason and the calculation.
The smallest number is 67/1000, then 0.672, then 68%, then 0.7, and the largest is 0.7
Answer:
solve for X
17-4x=33
-4x=33-17
-4x=16
-4x/-4=16/-4
x=-4
Step-by-step explanation:
1. move the constant (17) to the right side
2. subtract the numbers on the right side (33-17)
3. Divide both sides of the equation by -4 (/4)
4. write the answer x= -4
Solved.
