Answer:
(- 4, 1 )
Step-by-step explanation:
Given the 2 equations
y = x + 5 → (1)
x - 5y = - 9 → (2)
Substitute y = x + 5 into (2)
x - 5(x + 5) = - 9 ← distribute and simplify left side
x - 5x - 25 = - 9
- 4x - 25 = - 9 ( add 25 to both sides )
- 4x = 16 ( divide both sides by - 4 )
x = - 4
Substitute x = - 4 into either of the 2 equations and evaluate for y
Substituting into (1)
y = - 4 + 5 = 1
Solution is (- 4, 1 )
For this type of question, we have to take out the percentage of each candidate:
For Arthur
85 from 95
Convert 95 to 100
That means that we have to add 5, do the same thing with 85. Add 5 to 85 and you get 90. That means Arthur got 90% For Miguel 64 from 76. Covert 76 to 100. That means we have to add 24. Do the same thing with 64. Add 24 + 64. It equals 88% Miguel got 88%
Answer:
21
Step-by-step explanation:
Factors of 35 = 1,5,7 and 35
Factors of 15 = 1,3,5 and 15
=> Largest prime number that is a factor of 35 = 7 (7 is a prime number)
=> Smallest prime number that is a factor of 15 = 3 ( 1 is neither a prime no. nor a composite one)
<u><em>Their Product:</em></u>
=> 7×3
=> 21
