If you are solving for the question in the picture your answer would be 18. Whiich is letter A.
12x+15y=390 Original Equation
12(10)+15y=390 Replace x with 10
120 + 15y= 390 Mutiply 12 by 10
-120 = -120 subtract 120 on both sides to simplfy the equation
15y= 270 New equation
÷15 = ÷15 To get the variable alone divide 15 on both sides
y=18 Your value for y.
The first thing you should know in this case is that a circumference has a total measure in 360 degrees.
We have then that the formula to find EG in this case is:
EG + GF + FE = 360
We cleared EG:
EG = 360-GF-FE
We substitute the values:
EG = 360-83-66
EG = 211
Answer
EG = 211 degrees.
Answer:
$167.50
$1507.50
$134
Step-by-step explanation:
Given that:
Cost of sound system = 1675
APR, = 12%
Down payment = 10%
Number of monthly payments = 12
r = 0.12 / 12 = 0.01
Amount of down-payment :
10% * cost of sound system
0.1 * 1675 = $167.50
Amount to be financed :
$1675 - $167.50
= $1507.50
Monthly repayment :
Using the relation :
A / {[(1+r)^n]-1}/[r(1+r)^n]
1507.5 / (1+0.01)^12-1)/(0.01(1+0.01)^12)
1507.50 / 0.1268/(0.01 * 1.1268)
1507.50 ÷ (0.1268/0.01126)
1507.50 ÷ 11.25
= $134
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:
1 hour and 45 mins
Step-by-step explanation:
As mentioned,
Starting time = 2:30 PM
Ending time = 4:15 PM
The given time is in hours and minutes, to calculate the duration of movie, time should be converted into a same unite minutes.
1 hour = 60 minutes
Therefore,
2:30 = 2 hours and 30 mins = 2*60 + 30 mins = 150 mins
4:15 = 4 hours and 15 mins = 4*60 + 15 mins = 255 mins
The duration = Ending time - Starting time
=> 255 - 150
=> 105 mins
or
60 + 45
1 hour and 45 mins
