How do I solve this?
Answer: 2l+2w=48
Subtract 2w from both sides.
2l=48−2w
Divide both sides by 2.
2
2l
=
2
48−2w
Dividing by 2 undoes the multiplication by 2.
l=
2
48−2w
Divide 48−2w by 2.
l=24−w
Answer:
14centimeters
Step-by-step explanation:
from our equation,
2l + 2w = 48
we know that the width = 10cm
so,
2l + 2( 10 ) = 48
2l + 20 = 48
2l = 48 - 20
2l = 28
divide through by 2
2l / 2 = 28 / 2
l = 14
therefore,
l = 14 centimeters

What is the slope of this line?
The slope of horizontal lines is zero because they are straight with no curve.
The slope is calculates using the rise over the run.
Rise= How many units we move up. Here we move 0 units.
Whatever the run is (NOT 0) if we divide 0 by the run, we will get 0.
Diagonal lines always have slope.

What are the values of x and y?
Answer:
D should be correct
Step-by-step explanation:
Lets create an equation.
7x + 1 + 4x - 8 + 120 + 12y = 360
We will now try all options to see which one fits perfectly.
----------------------------------------------------------------------------------
A) x = 3, y = 10
7(3) + 1 + 4(3) - 8 + 120 + 12(10) = 360
=> 21 + 1 + 12 - 8 + 120 + 120 = 360
=> 266 ≠ 360 (False)
----------------------------------------------------------------------------------
B) x = 1, y = 12
7(1) + 1 + 4(1) - 8 + 120 + 12(12) = 360
=> 7 + 1 + 4 - 8 + 120 + 144 = 360
=> 268 ≠ 360 (False)
----------------------------------------------------------------------------------
C) x = 32, y = 10
7(32) + 1 + 4(32) - 8 + 120 + 12(10) = 360
=> 224 + 1 + 128 - 8 + 120 + 120 = 360
=> 585 ≠ 360 (False)
----------------------------------------------------------------------------------
D) x = 17, y = 5
7(17) + 1 + 4(17) - 8 + 120 + 12(5) = 360
=> 119 + 1 + 68 - 8 + 120 + 60 = 360
=> 360 = 360 (True)

Answer:
$54196.92
Step-by-step explanation:

1.0825 is the multiplier
The correct answer is $54196.92.
Step by step =
6900x1.0825^26 = 54196.92.
How do you calculate the annual interest rate?
The formula and calculations are as follows:
Effective annual interest rate = (1 + (nominal rate / number of compounding periods)) ^ (number of compounding periods) - 1.For investment A, this would be: 10.47% = (1 + (10% / 12)) ^ 12 - 1.And for investment B, it would be: 10.36% = (1 + (10.1% / 2)) ^ 2 - 1.Is the interest rate annual or monthly?
The interest rate is the amount a lender charges a borrower and is a percentage of the principal of the amount loaned. The interest rate on a loan is typically noted on an annual basis known as the annual percentage rate (APR).
