ANSWER: x=7, y=19
Steps
1. Substitute y=2x+5
3x+2x+5=40
2. For y=2x+5 , Substitute x=7
y=2 * 7+5
3. 2 * 7+5=19
y=19
The third factor 42 because 6 * 7 is 42
so 6 is a factor of 42. you can't do this with the other numbers
Answer:
Yes, -13 is less than f/2.
Step-by-step explanation:
Since we are given a fraction with a variable, it may seem hard at first to find out which number is greater.
First, we have to realise that -13 is a negative number. Any negative number is always equal to less than a positive number.
Whatever number we replace our variable f with, whether it be 2, 3, 9, or 0.00000000000001, we can rest assure that it will be a <em>positive</em> number.
Since positive numbers are greater than negative ones, -13 has to be less than f/2.
If the fraction was negative (- f/2), this would be a nearly impossible question to answer.
Answer: A would be angle "O" sine both triangle PNO and LMO share the same angle
S would be ON = LM ( as shown)
A would be angle "L" and angle "N" or angle "P" and angle "M" ( the side is opposite of each other)
