First, distribute the 5 into the 8x-1 (5 times 8x, 5 times -1)
40x - 5 - x = 2x + 32
Subtract the x
39x - 5 = 2x + 32
Switch the sides for -5 (it will become positive and add to the 32)
39x = 2x + 37
Switch sides for the 2x (it will become negative and subtract from the 39x)
37x = 37
Divide both sides by 37
x = 1
Answer:
The measurement of EF is 1.98 units
Step-by-step explanation:
In Δ DEF
∵ m∠E = 90°
∴ FD is the hypotenuse of the triangle
∵ m∠D = 26°
∵ EF is opposite to angle D
- We can use the sine ratio to find it
∵ sin D = 
⇒ (opposite side / hypotenuse)
∵ FD = 4.5 units
∴ sin(26) = 
- Multiply both sides by 4.5
∴ 4.5 sin(26) = EF
∵ sin 26° ≈ 0.44
∴ 4.5(0.44) = EF
∴ 1.98 = EF
The measurement of EF is 1.98 units
Answer:

Answer:
independent and 3/8
Step-by-step explanation:
independent because you didn't take another one out
6/16 which equals to 3/8
