Answer:
419.5 ft of BX cable
step-by-step explanation:
12x8.5ft= 102 ft
7x18.5 ft= 129.5ft
24x 1.75ft= 42ft
12x 6.5ft=78 ft
2x 34.25= 68.5ft
Add all the answers and you get 419.5 ft

Answer:
You got your negatives messed up. The answer was -5y-4x
Step-by-step explanation:
Expression: -8y + 5x + 3y -9x
Your objective: Simplify the expression
The First step, Combine like terms meaning -8y+3y and -9x+5x
Solve, -8y+3y
That would equal -5y
Next solve -9x + 5x
That would equal -4x
Write your expression in simplest form:
-5y-4x
What you did:
You combined like terms but didn't follow the negative rules
Remember: Positive and Negative = Negative
Negative and Negative = Positive
For example -8y + 3y
You chose to add -8 and 3 which you got -11
What you were supposed to do was to subtract.
A helpful trick: Since they are like terms you could rearrange the questions like this 3y-8y+5x-9x, You can see that you have to do subtraction left to right
3y-8y= -5y
5x-9x= -4x
Solution: -5x-4x
Answer:
Look below.
Step-by-step explanation:
One property of a cyclic quadrilateral is that the opposite angles are supplementary. Angles ABC and ADC are opposite; therefore, supplementary. We know that angle x is supplementary to angle ABC because they are on the same line. We know that angle y is supplementary to angle ADC because they are on the same line.
ABC + ADC= 180 degrees
ABC + x= 180 degrees
ABC + ADC = ABC + x
- ABC -ABC
ADC= x
ADC+ y= 180 degrees
ADC + ABC= 180 degrees
ADC+y= ADC+ABC
-ADC -ADC
y=ABC
ABC=x ADC=y
ABC + ADC= 180
Property of substitution:
x+y=180
Multiply by 200. and you will get the correct answer.
