If said number is x, that means that twice (2 times) a number and 2x-7=13. Adding 7 to both sides, we get 2x=20 and by dividing both sides by 2 we get x=10. For 2, we see that the sum of a number and 6 is first priority, so we have (x+6)*7=-43. Dividing both sides by 7, we get x+6=-43/7. After that, we subtract both sides by 6 to get -43/7-6=x
Answer:
11°
Step-by-step explanation:
Kindly find the diagram attached.
From the diagram we are given two interior angles ∠NLM and ∠LMN and exterior angle ∠MNO.
You must understand that sum of interior angles is equal to the exterior angles.
∠NLM+ ∠LMN = ∠MNO
Given parameters
∠NLM = x-4
∠LMN = x+9
∠MNO = 4x-17
Substitute the given parameters into the equation above;
x-4+x+9 = 4x-17
2x+5 = 4x-17
2x-4x=-17-5
-2x = -22
x = -22/-2
x = 11°
Hence the value of x is 11°
1: w=3
2:w=-4
( 1): ''w2'' was replaced by ''w^2''
w^2+w-(12)=0
