Answer:
Harry has 120$
Step-by-step explanation
6x+5x=220
11x=220
/11 /11
x=20
6 * 20 = 120
I'd apptreciate help w my questions if u can :)
Answer:
x = 3
Step-by-step explanation:
7 + 6x - 4 = 3x - 9 + 7x
6x -3x - 7x = -9 - 7 + 4
-4x = -12
-4x/-4 = -12/-4
x = 3
U will get like decimal places so i suggest u round it up to 3 significant figure
There are several ways to solve this problem. The easiest one is by trigonometry. I am going to apply this method. If you didn't see trigo yet, I will use the triangles semi equilateral.
Let BD, be the wall on the left and CE on the right (B and D = base of the wall)
1) In Δ BAD, angle BAD = 60°→→ tan (60) =(opposite side)'(adjacent) =BD/DA
tan (60) = 60/DA , but tan (60) = √3 →→√3 = 60/DA or DA = 60/√3
And DA = 34.64
2) In Δ ACE, angle CAE = 30°→→ tan (30) =(opposite side)'(adjacent) =EC/AE
tan (30) = 40/AE , but tan (30) = √3/3 →→√3/3 = 40/AE or AE = (40)/(√3/3)
And AE = 68.28
3) Distance between walls = DA + AE = 34.64 + 68.28 = 103.92
(If you didn't study trigo yet, do let me know then we will solve it with the semi equilateral triangles
