Answer:
<em>4.5%</em>
Step-by-step explanation:
From the question, we are informed that Diego measured the length of a pen to be 22 cm while the actual length of the pen is 23 cm.
The percentage decrease:
= (23 - 22)/22 × 100
= 1/22 × 100
= <em>4.5%</em>
good luck :)

Answer:
c + (a + 1.70) = 6.70
Step-by-step explanation:
you start the equation by Subtracting how much more alan has to the total
(this will only be set as an equation do not actually solve it)
then add 1.70 to a
"
6.70 - 1.70 = a + c
(1.70 + a)
c + (a + 1.70) = 6.70 "
In order to solve you must find the value of the blank angle.
Here is your first equation.
126 + x = 180
Subtract 126 from both sides.
x = 54
So now add up all the angles.
x + (2x + 6) + 54 = 180
Combine like terms.
3x + 60 = 180
Subtract 60 from both sides.
3x = 120
Divide.
x = 40
Now check your answer.
40 + 2(40) + 6 + 54 = 180
40 + 80 + 6 + 54 = 180
120 + 60 = 180
180 = 180
There is a solution. The answer is 40.
I hope this helps love! :)
