15/12
Answer:
$55
Step-by-step explanation:
Start with $245.
Calculate to total money the commuter needs to buys 20 weeks of tickets.
Multiply the number of weeks by the price per week.
20 X $15 = $300
He will need $300 for 20 weeks of tickets.
Subtract what he has from the amount he needs.
$300 - $245 = $55
Therefore the commuter will need to add $55 to the account to afford tickets for 20 weeks.
If there's only 1 table, then you need 5 roses total (5*1 = 5)
If there are 2 tables, then you need 10 roses total (5*2 = 10)
If there are 3 tables, then you need 15 roses total (5*3 = 15)
If there are 4 tables, then you need 20 roses total (5*4 = 20)
At this point, you probably see the pattern: you multiply 5 by the number of tables to get the total number of roses. So it would look like this equation
(number of roses) = 5*(number of tables)
r = 5*x
where r is standing in for "number of roses" as shorthand; also, x is standing in for "number of tables".

Final Answer: r = 5x (lower right corner choice)
Note that 5*x is the same as 5x (both of which mean "5 times x)
Answer:
≈ 0.9 cm²
Step-by-step explanation:
I don't know if there is any easier way to solve this, I use 8th grade slope and line method to solve. suppose A is on origin, then the coordinates of triangle ABC are (0,0) (1,3) (4,1) and polygon DEFGH intersect line BC at F and G.
F is the intersect of y=2 and line BC, while G is intersect of x=3 and line BC.
Line BC: pass (1,3) and slope (m) = (1-3)/(4-1) = - 2/3,
F(x,2)
(2-3) / (x-1) = -2/3
2x-2 = 3 x = 2.5
*<u>F (2.5 , 2</u>)
G (3,y)
(y-3) / (3-1) = -2/3 y = 5/3
*<u>G (3 , 5/3)</u>
*<u>point I (3 , 2</u>)
segment FI = 3-2.5 = 0.5 = 1/2
segment GI = 2 - 5/3 = 1/3
area ΔFIG = (1/2 * 1/3) / 2 = 1/12 = 0.083
area of polygon DEFGH (region colored RED) = 1 - 0.083 = 0.917 ≈ 0.9 cm²
