Answer:
x¹²,8x⁴,6x,2x,1
Step-by-step explanation:
x²×x⁶×x⁴=x¹²
x^4(8) =8x⁴
x^1(6) =6x
x^1(2) =2x
x^0 = 1
The answer is 20.
5*10-5*6=50-30=20
52% of 200
52/100=26/50=13/25•200/1= 2600/25=2600 divided by 25 is 104
The answer is 104
Answer:
x = -9/4
Step-by-step explanation:
−2(x + 1/4) + 1 = 5
Subtract 2 from both sides.
−2(x + 1/4) = 4
Divide both sides by -2.
x + 1/4 = -2
Subtract 1/4 from both sides.
x = -2 1/4
x = -9/4
