Answer:
Length is 38
inches
Width is 16
inches
Step-by-step explanation:
Let the width be x inches
The length will be 2x + 5 inches
The perimeter is 110 inches
Perimeter is given by (2 × length) + (2 × width)
2(2x + 5) + 2x = 110 inches
4x + 10 + 2x = 110 inches
6x = 100 inches
x (width) = 100/6 = 16
inches
Length = 2(100/6) + 5 = 38
inches.
Answer:
A) y=2x+12. ( replace y with 5x) ➡️ 5x=2x+12 y=5x 5x-2x=12
➡️ 3x=12
3x/3=12/3
x=4
B) y=5x
y=5×4
y=20

Answer:
$12000 at 5%
$27000 at 6.5%.
Step-by-step explanation:
Let x represent amount invested at 5% and y represent amount invested at 6.5%.
We have been given that a combined total of 39000 is invested in two bonds. We can represent this information in an equation as:

We are also told that the annual interest rate is 2355.00. We can represent this information in an equation as:

Upon substituting equation (1) in equation (2), we will get:







Therefore, an amount of $12,000 is invested at 5%.
Upon substituting
in equation (1), we will get:



Therefore, an amount of $27,000 is invested at 6.5%.
