Answer:
£1.31
Step-by-step explanation:
Add 5 to 3, obtaining 8. Then the amt tht Eric pays is 5/8 of the £3.50 total, and the amt tht Sue pays is 3/8 of the total.
Thus, mult. £3.50 by 3/8:
(3/8)(£3.50) = £1.31 (which has been rounded off from £1.3125).
Answer: 2 + √10 , 2 − √10
Step-by-step explanation:
-5x(x-4) = -30
divide by -5
x(x - 4) = -30
distribute the x
x^2 - 4x = 6
move the 6 to the left to have the equation equal zero
x^2 - 4x - 6 = 0
plug into the quadratic formula & solve
x
= 2 + √10 , 2 − √10
40 - 28 do that and you'll get your answer
The correct answer would be D
