Answer:
y=0.75m+45
Step-by-step explanation:
when you bought the car it was 45, that doesnt change so its a constant
but every mile you drive, it changes, therefore it becomes the dependent or the rate :)
so we just make it into an equation of
y=0.75m+45
where y= the total amount of money owed
and if you wanted to solve for how far the car drove, plug in the 222.5 in for y, as that was the amount owed and solve!
222.5=0.75m+45
177.5=.75m
now divide by .75
m= 236 2/3 miles
hope this helped :))

Answer:
1. 0
2. 18 th term
3. 209
4. 670
Step-by-step explanation:
1. n^th term of an A.P = a + (n - 1)d , where n is the term
6 = a + (5 - 1)d ... (i)
5 = a + (6 - 1)d ... (ii)
a + 4d = 6 ... (i)
a + 5d = 5 ... (ii)
Subtracting (ii) - (i) we get;
0 + d = -1 , d = -1
So the common difference (d) = -1
And first term (a);
a + 4(-1) = 6
a = 6 + 4 = 10
11^th term will be;
= 10 + -1(11 - 1) = 10 - 10 = 0
2. The A.P is;
1, 4, 7, 10, 14, ....
The first term (a) = 1
The common difference (d) = 3
= a + (n - 1)d
52 = 1 + (n - 1)3
3n - 3 + 1 = 52
3n = 52 + 2 = 54
n = 54/3 = 18 th term
3. The A.P is;
4, 9, 14, ... , 254
The first term (a) = 4
The common difference (d) = 5
= a + (n - 1)d
To find what term number 254 is;
254 = 4 + (n - 1)5
5n - 5 + 4 = 254
5n = 254 + 1 = 255
n = 255/5 = 51
The 10^th term from the end of the AP is the 42^nd term.
= 4 + (42 - 1)5 = 4 + 205 = 209
4. The A.P is;
5, 8, 11, 14, ...
The first term (a) = 5
The common difference (d) = 3
Sum of n terms in an A.P is given by;
=
(2a + (n - 1)d)
=
(10 + 19(3) = 10(10 +57) = 670
Answer: lesser x = 3.76 & greater x = 8.24
Step-by-step explanation: just took the test
Well, there's 1000 milliliters in one liter.
Do 1000 - 275.
You should get 775.
The answer is 775 milliliters of juice. <span />
