Answer:
What is this for?
Step-by-step explanation:
The answer is A
You would multiply the second equation by -2 to clear the 'y'.
This leaves -10x = 2B and 3x = A
When combining these we get -7x = A - 2B
Step-by-step explanation:
(x + 20)º and (4x - 5)º are supplementary angles, meaning the sum of their angles = 180º.
(x + 20) + (4x - 5) = 180
5x + 20 - 5 = 180
5x + 15 = 180
5x = 165
165/5 = 33
Answer: x = 33
It depends on what is the width of framing and do we want to place it on painting or not but basically it is the circuit
Circuit = 2*71cm + 2*75cm=2*(71cm+75cm)=2*146cm=292cm
Answer:. U need 292cm of framing (at least).
