Answer:
6
Step-by-step explanation:
You take the most amount studied (18) and the least amount studied (12) and subtract them and that would be the range
To write the given phrase as an algebraic expression you can identify what does each part of the phrase mean:
59 less than: You have to substract 59 to the other part of the phrase
twice a number: as the number is n, twice a number is 2n
Then, you get the next algebraic expression:
Answer:
x = 12, y=7
x=30, y=25
x=15, y=10
Step-by-step explanation:
We have : y = x - 5
x = 12 then y = 7, y = 12 - 5 = 7
x = 30 25 = x - 5, x = 25 + 5 = 30
x = 15, y = 15 - 5 = 10, y = 10
Answer:
FALSE
Step-by-step explanation:
The sum of interior angles of a quadrilateral is 360° (or 400 grads or 2π radians--units matter).
