Answer: 2
Each time x increases by 2, the outputs are multiplied by 4 (eg: 3 to 12 is times 4, or 12 to 48 is times 4)
Take the square root of 4 to get 2. So each time x increases by 1, y is doubled
x = 0, y = 3
x = 1, y = 6 <<-- y is doubled
x = 2, y = 12 <<-- y is doubled
and so on
<span>Set up a proportion so 12/5= 30/x so cross multiply 5 times 30 is = to 12x now divide 150 (which is 30 times 5) by 12 and you get 12.5. So 12.5 is your answer
</span> y 12 - x 5
y 30 - x ?
x= 30 × 5 ÷ 12
<span>x = 12.5</span>
The answer is A) In a right triangle, the square of the length of the hypotenuse equals the sum of the square of the lengths of the legs
Question 16
Given
Two golfers completed one round of golf.
The first golfer had a score of +6 and the second golfer had a score of -3.
To determine:
How many more shots did the first golfer take?
Explanation
Let 'n' be the number of shots taken by the first golfer
Since the first golfer had a score of +6 and the second golfer had a score of -3.
It means the 1st golfer must be 6 over par, and the 2nd golfer is still under 3.
Hence, we can map the situation using an equation
Adding -3 to both sides of the equation
Therefore, the 2nd golfer took 9 more shots.
Question 17
Answer:
The balance will be: 55
Step-by-step Explanation:
Credit means:
Debit means:
Hence, we can determine the balance using the equation.
Balance = 84 + (-29)
= 84 - 29
= 55
Therefore, the balance will be: 55
Answer:
12
Step-by-step explanation:
8x+4x = 12x
-3+3= 0
12x+0=180
x=180/12
x=15
