Answer:
20.7%
Step-by-step explanation:
3/14.5 = 0.2068
Take 0.2068 and multiply it by 100 to get its percent value which is about 20.7%
$3.00 is 20.7% of $14.50
The simplified algebraic expression for the model is x = -1
<h3>What are algebraic expressions?</h3>
Algebraic expressions are known as mathematical statements gotten when operations such as addition, subtraction, multiplication, division, etc. are operated or used on variables and constants
From the figure given;
We have:
Now, let's add the variables
= x + x - x
= 2x - x
= x
For the constants
= -1^6 = -1
= 1 ^5 = 1
= 1 × -1 = -1
Thus, the simplified algebraic expression for the model is x = -1

115°
A triangle is 180° so add the two degrees given and subtract that from 180; 180-(75+40)
180-155= 65. then a line is 180 degrees so you subtract 65 from 180 and get 115
Write down the two numbers, one under the other, with the decimal points lined up.
Add zeros so the numbers have the same length.
Then subtract normally, remembering to put the decimal point in the answer.
