All you do is subtract 81 from 9 and it’s 72 from what I understood from your question
Step-by-step explanation:
well, the arcs WS and ST together are the full half-circle and therefore 180°.
that means
5x + 37 + 3x - 9 = 180
8x + 28 = 180
8x = 152
x = 19
6/15 in simplest form is 2/5.
Divide the numerator and denominator by 3. :)
God bless
Answer:
see explanation
Step-by-step explanation:
Note there is a common ratio between consecutive terms of the sequence, that is
- 450 ÷ 15 = 13500 ÷ - 450 = - 405000 ÷ 13500 = - 30
Thus to obtain the next term in the sequence multiply the previous term by - 30
start with 15 and multiply by - 30
A) The x-axis represents minutes used per month. The y-axis represents cost in dollars. Following the line of the graph indicating 60 minutes per month it shows Plan A costs $6 per month while Plan B costs $12 per month.
Plan A is cheaper.
Difference in prices = cost of Plan B for 60 minutes per month - cost of Plan A for 60 minutes per month
= 12 - 6 = $6 per month
b) To solve, identify where the lines of Plan A and Plan B intersect. Both lines intersect at 160 minutes per month.
Which plan costs less when less minutes are used? To solve, identify which line has a lower cost on the y-axis. Plan A costs less if less than 160 minutes are used.
