C = 1.39 + 0.5(n - 1), where C is the cost and n is the number of days
C = 1.39 + 0.5(6)
C = $4.39
X=2+5y
x-y=30
basically, all you're doing here is solving a system of equations. use the second equation to find out what x or y means. i'm going to solve it for x.
this is the new equation : x=30+y
now i plug this equation into the first one.
30+y=2+5y
30=2+5y-y
30=2+4y
28=4y
y=7
now that you know what y is, take that second equation we did in the beginning and plug in y.
x-7=30
solve for x
x=37
the two integers are 37 and 7.
Answer:
Not sure but :
Y=15/7
X=13/5
Z=26/7
I will check them later and tell you if they are right or not .
Step-by-step explanation:
y power 2 : 31 × 8 = 248
Rad 248 = 15/7
x power 2 : 23 × 8 = 184
Rad 184 = 13/5
31 power 2 : (15/7) power 2 + z power 2
961 = 246/49 + z powe 2
z power 2 = 714/51
rad 714/51 = 26/7
z = 26/7
$709.21
$361.36 for week one + $347.85 for week two = $709.21 total for both weeks
