Step-by-step explanation:
24-6
She must have a score greater than 69 in her final tests
Let the required score be "x"
<h3>What is Mean?</h3>
The mean of the data is the ratio of the sum to the total sample
Mean = 80+76+85+85+x/5
80+76+85+85+2x/5 > 79
326+x/5 > 79
326 + x > 395
x > 395 - 326
x > 69
This shows that she must have a score greater than 69 in her final tests

Answer:
(2, 5 )
Step-by-step explanation:
Given the 2 equations
2x + 3y = 19 → (1)
6x + 2y = 22 → (2)
Multiplying (1) by - 3 and adding to (2) will eliminate the x- term
- 6x - 9y = - 57 → (3)
Add (2) and (3) term by term to eliminate x
0 - 7y = - 35
- 7y = - 35 ( divide both sides by - 7 )
y = 5
Substitute y = 5 into either of the 2 equations and solve for x
Substituting into (1)
2x + 3(5) = 19
2x + 15 = 19 ( subtract 15 from both sides )
2x = 4 ( divide both sides by 2 )
x = 2
solution is (2, 5 )
