Answer: 28
Step-by-step explanation:
The 7th term of an AP is 4 and its common difference is -4. The 7th term of an arithmetic progression is written as:
a + 6d = 4
where,
a = first term
d = common difference= -4
a + 6d = 4
a + 6(-4) = 4
a - 24 = 4
a = 4 + 24
a = 28
The first term is 28.
Answer:
A. 1
Step-by-step explanation:
Following order of operations, you would multiply 4/3 and 3/5.
Once you do this, you will get 12/15, which you can simplify to 4/5
Then you add the 1/5 with the 4/5 and you will get 5/5, which is equivalent to 1
Answer:
Let's denote: A(-4, 5), B(7, -9).
If P(x, y) is the midpoint of AB, then we have:
x = (-4 + 7)/2 =3/2
y = (5 + (-9))/2 = -2
=> P(3/2, -2)

F = .7p
add the original discount of 50% to the additional of 20%. the total discount is 70%. multiply the 70% (.7 as a decimal) by the original price (p) to find the final price (f).
