Answer:
The value of x = 20
Step-by-step explanation:
Given:
∠BOC = 3x - 15
∠COD = 2x + 5
Find:
The value of x
Computation:
⇔ ∠BOC + ∠COD = 90
⇔ 3x - 15 + 2x + 5 = 90
⇔ 5x - 10 = 900
⇔ 5x = 90 + 10
⇔ 5x = 100
⇔ x = 100 / 5
⇔ x = 20
The value of x = 20
It is already simplified because there is nothing you can divide into both 18 and 25 that would result in whole numbers.
Algebraic expressions are expressions that use numbers and variables
The value of A is 65/64
<h3>How to determine the value of A</h3>
The expression is given as:
Rewrite the expression as:
Factor out 2^x
Rewrite as product
The expression to compare with is given as: A * 2^x.
So, we have:
Divide both sides by 2^x
Take LCM
Hence, the value of A is 65/64

By using a change of units, we can see that the rate in dollars per liter is:
R = $0.0027 per liter.
<h3>
How to convert the rate?</h3>
Here we have a rate in dollars per cubic foot, and we want to rewrite this in dollars per liter. So we just need to apply a change of units.
The original rate is in dollars per square foot, and it is given by:
R = $1.30 for 16.7ft^3
We know that the relation between cubic feet and liters is:
1ft^3 = 28.32 L
Then, if we apply a change of units, we can rewrite the volume as:
16.7ft^3 = 16.7*(28.32) L = 472.9 L
Then the rate is $1.30 per 472.9 L, taking the quotient we get:
R = ($1.30/472.9 L) = $0.0027 per liter.
