Answer:
20° and 70°
Step-by-step explanation:
complimentary angle sum to 90°
let x be the compliment then the angle is 3x + 10 , so
x + 3x + 10 = 90 , that is
4x + 10 = 90 ( subtract 10 from both sides )
4x = 80 ( divide both sides by 4 )
x = 20
3x + 10 = 3(20) + 10 = 60 + 10 = 70
the 2 angle measures are 20° and 70°
Step-by-step explanation:
Check to see if there is a number before (to the left of) the decimal. If there is, this number is the whole number of the fraction. So, 3 is the whole number. Place the number that falls after (to the right of) the decimal in the numerator; then use the decimal placement to determine the denominator.
Answer:
D. A number of books and their cost that is not possible with either subscription.
Step-by-step explanation:
If you look at the 2 lines on the graph, you see that the blue line represents the first subscription which charges a 96 dollar annual fee, and the red line represents the other subscription which charges 3 dollars per book.
Every point along these lines shows a price that could possibly be paid and a number of books that could be bought. The point where these two lines meet is where the amount of books borrowed and the price for those books is the same for both subscriptions.
Because point S is not at this intersection, nor is it on either of these lines, it is not possible to pay that price for that amount of books with either subscription.
