Answer:
Step-by-step explanation:
- 10560 feet ⇒ 2 miles
- 10560/2 feet ⇒ 2/2 miles Divide both by 2 to find the unit ratio
- 5280 feet ⇒ 1 mile
- 5280*3 feet ⇒ 1*3 miles Triple both to find required number
- 15840 feet ⇒ 3 miles
$1.50C + $4A= $5050
C + A = 2200
-4(C + A = 2200)
-4C - 4A = -8800
1.50C+4A = 5050
-----------------------
-2.5C =- 3750
-2.5C/-2.5 =- 3750/-2.5
C = 1500
C + A = 2200
1500 + A =2200
1500 - 1500 + A = 2200 - 1500
A = 700
CHECK
$1.50C + $4A= $5050
$1.50(1500) + $4(700)= $5050
$2250 +$2800 =$5050
$5050 = $5050
C + A = 2200
1500 + 700 =2200
2200 = 2200
Answer:
,

.
Step-by-step explanation:
The value of 
is the first value of the geometric series, that is, .
If the series represents a geometric sequence, then 
must be constant for every consecutive pair of elements, that is:
Since 
, .
The geometric sequence can be represented by the following formula:
, for 
The 12th element of the geometric sequence is: (, , 
)
10/2x2= 10
Explanation:
10 divided by 2=5
5x2=10
Step-by-step explanation:
x²y = k, where k is a real constant.
When x = 3.5, y = 8.
=> (3.5)²(8) = k, k = 98.
When y = 8/9,
we have x²(8/9) = (98).
=> x² = 110.25
=> x = 10.5 or x = -10.5.
Since we want the negative value,
the answer is x = -10.5.
