Let n = number
"3 times the sum of a number and 7" translates to 3(n + 7)
"2 less than five times the number" translates to 5n - 2
The word "is" becomes the equals sign.
3(n + 7) = 5n - 2
I think you already asked this one.
Answer:
- Missing side length is 5 cm.
Step-by-step explanation:
<u>Multiply 20 by 12:</u>
<u>Multiply 240 by 5:</u>
<u>Multiply the lengths:</u>
S=d/t so in this case it's 75/12 which is 6.25. Round it and you got 6 miles per hour.

Answer: The answer is P'(7, 17.5) and Q'(7, 3.5).
Step-by-step explanation: Given that a line segment PQ is dilated with a scale factor of 3.5 where origin is the centre of dilation.
The end points of segment PQ are P(2, 5) and Q(2, 1).
Therefore, after dilation, the coordinates of the end points become
Thus, the coordinates of P' are (7, 17.5) and the co-ordinates of Q' are (7, 3.5).
