The factors of 189 are: 1, 3, 7, 9, 21, 27, 63, 189.
1 × 189 = 189
3 × 63 = 189
7 × 27 = 189
9 × 21 - 189
Sin A = 56/75
A = sin^-1 (56/75) = 48.30 degrees
Answer:
The linear equation is V - IR =0
The total current is 2.5 amps
Step-by-step explanation:
According to ohms law, the voltage (V) applied is directly proportional to current (I)
Therefore, V = IR
V - IR = 0 (R is resistance)
When V = 20, I = 1
The 1st equation is 20 - R = 0
When V = 60, I = 3
The 2nd equation is 60 - 3R = 0
From the 1st equation, R = 20
Substiting R = 20, V = 50 into the linear relation V - IR = 0
50 - 20I = 0
50 = 20I
I = 50/20 = 2.5 amps
Answer:
x = 0
Step-by-step explanation:
-2(2 − 2x) = 4 − 8(1 − x)
Apply the distributive property:
−2(2 − 2x) = 4 − 8(1 − x)
(−2)(2) + (−2)(−2x) = 4 + (−8)(1) + (−8)(−x)
−4 + 4x = 4 + (−8) + 8x
Combine like terms:
4x − 4 = (8x) + (4+−8)
4x − 4 = 8x + (−4)
4x − 4 = 8x − 4
Subtract 8x from both sides:
4x − 4 − 8x = 8x − 4 − 8x
−4x − 4 = −4
Add 4 to both sides:
−4x − 4 + 4= −4 + 4
−4x = 0
Divide both sides by -4:
-4x/-4 = 0/-4
<u>x = 0</u>
