Answer:
n = 24
Step-by-step explanation:
From the question,
The formula for the sum of the term in an AP is given as
Sₙ = n(a+L)/2.................. Equation 1
Where Sₙ = sum of the nth term, n = number of term, a = first term, L = last term.
make n the subject of the equation
n = 2Sₙ/(a+L)................. Equation 2
Given: Sₙ = 420, a = 4, L = 31
Substitute these values into equation 2
n = (2×420)/(4+31)
n = (840)/35
n = 24.
Hence, n = 24
At what point do the lines y = 6x – 18 and
y=8x – 32 intersect?
Answer:
(7, 24)
Step-by-step explanation:
Solve the system:

24x + 32 − 2.1x = 20.9x + 30 + x + 2
Answer:
All real numbers are solutions. (Infintie Solutions any number)
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
24x+32−2.1x=20.9x+30+x+2
24x+32+−2.1x=20.9x+30+x+2
(24x+−2.1x)+(32)=(20.9x+x)+(30+2)(Combine Like Terms)
21.9x+32=21.9x+32
21.9x+32=21.9x+32
Step 2: Subtract 21.9x from both sides.
21.9x+32−21.9x=21.9x+32−21.9x
32=32
Step 3: Subtract 32 from both sides.
32−32=32−32
0=0

All "real"numbers are solutions, infintiely many solutions

1. If you wanted to make a triangle with side lengths of 3 units, 3 units, and 4
units, how would you know at what angle you should position the sides?
Answer:
Since 4 is the largest number its the hypotenuse. The two 3s are equal so they are interchangeable so it doesn't matter where you put them. If its a right triangle the hypotenuse is opposite the right angle.

Answer:
$1,150.00
Step-by-step explanation:
We calculate using the Equation below
A = P(1 + rt)
P = Principal (Initial Investment) = $1000
Interest rate = 3%
Time = 5 years
A= Amount after time t?
Calculation:
First, converting R percent to r a decimal
r = R/100 = 3%/100 = 0.03 per year.
Solving our equation:
A = 1000(1 + (0.03 × 5)) = 1150
A = $1,150.00
The amount of is investment is $1,150 after 5 years.
