Answer: 15 miles
Step-by-step explanation:
The equation is 5.25+1.25x=24 where x is each additional mile so to solve for x it would be 1.25x=18.75 and divide both sides to solve for x
Answer: $2,370
Step-by-step explanation:
If she increases her monthly payments by 10 each month, then the rate at which it is increasing is in arithmetic progression. The formula for determining the sum of n terms of an arithmetic sequence is expressed as
Sn = n/2[2a + (n - 1)d]
Where
n represents the number of terms in the arithmetic sequence.
d represents the common difference of the terms in the arithmetic sequence.
a represents the first term of the arithmetic sequence.
From the information given,
n = 18 months
a = $42.50
d = $10
Therefore, the sum of the first 18 terms, S18 would be
S18 = 18/2[2 × 42.5 + (18 - 1)10]
S18 = 9[85 + 170)
S18 = 9 × 255 = $2295
The amount that she paid for the refrigerator the end of the 18 months is
2295 + 75 = $2370

X= a number
(2x+4)/3 + (x+2)= 20
Multiply everything by 3 to eliminate the fraction
(3/1)((2x+4)/3) + (3)(x+2)= (3)(20)
2x+4+3x+6= 60
5x+10=60
Subtract 10 from both sides
5x=50
divide both sides by 5
x=10
Check:
Substitute answer in original equation
(2x+4)/3 + (x+2)= 20
(2(10)+4)/3+(10+2)= 20
(20+4)/3+12= 20
24/3+12= 20
8+12= 20
20=20
Hope this helps! :)
