17/50 is 34% as a fraction!
1st let's calculate r the common ratio:
r = (-20)/4 = (100/-20) = -5
Value of nth term = a₁.rⁿ⁻¹, where a₁= 1st term and n, the rank
Value of nth term = 4r⁽⁷⁻¹⁾ = 4.(-5)⁶
Value of nth term = 62,500
Answer:
10
Step-by-step explanation:
40/4= 10
-1/4x + 5 = 3/4, subtract 5 from both sides to get -1/4x = -4 1/4, then divide both sides by -1/4 to get x = 17. You can check by plugging 17 in for x in the equation.
-1/4 * 17 + 5 = 3/4
3/4 = 3/4 so it's right
