the problem description is incomplete or wrongly copied.
we don't know the thickness of the boards, and we cannot understand what we need to calculate, and what the answer options are.
Answer:
x=48
Step-by-step explanation:
10x-20+6x+8=180 set the equations together and to equal 180 since a line is 180 degrees
Get the variables together
10x-20+6x+8=180
-6x -6x
4x-20+8=180
add together -20 and 8
4x-12=180
add -12 on each side
4x-12=180
+12 +12
4x=192
divide all by 4
x=48
'a' i think sorry if wrong
Answer:
Equation is | x-20 | = 2
Min = 18
Max = 22
==================================================
Explanation:
x = number of strawberries
|x-20| = distance from x to 20 on the number line.
Absolute value is used to ensure the distance is never negative. This distance represents how far off from 20 we are.
For instance, let's say the package had x = 17 strawberries
|x-20| = |17-20| = |-3| = 3
We're 3 units away from the goal of 20
--------------------
Setting |x-20| equal to the error of 2 will help us find the min and max
|x-20| = 2
x-20 = 2 or x-20 = -2
x = 2+20 or x = -2+20
x = 22 or x = 19
The smallest amount is 19 strawberries, while the most is 22. This represents the min and max respectively.
