Find the value of y
------------------------------------------------------------------------
y - 18 = 14
+ 18 + 18
y = 32
------------------------------------------------------------------------
substitute y = 32 into 2 (y + 9)
------------------------------------------------------------------------
2( y + 9 ) = 2 ( 32 + 9 )
2 (y + 9 ) = 2 (41)
2 ( y + 9 ) = 82

Answer:
C
Step-by-step explanation:
Answer: 110
Step-by-step explanation:
Given;
Total cost C = $151
Enrollment fee E = $30
Charge per 10 test t = $11
n is the number of packet of test taken.
The questions can be represented by the equation below;
30 + 11n = 151
Substracting 30 from both sides.
11n = 151-30 = 121
n = 121/11
n = 11
Since the number of packet of test is 11 and each packet contains 10 tests. The number of test N is given by;
N = 10 n = 10 ×11 = 110
N = 110
Answer:
6.06 x 
Step-by-step explanation:
(5.25 x 
) / (8.7 x 
)
= (5.25 x ) x( )/ (8.7 )
= (5.25 x 
)/ (8.7 )
= 0.606 x 
= 6.06 x
