This is obviously B, you can get the answer through guess and check with a calculator or just take everything out that makes no sense at all like D and A and then figure out your final answer with the last 2 that make sense
1) 100% - 30% = 70% - remainder
70% = 0,7
50% = 0,5
2) 0,5 * 0,7 = 0,35 = 35% - made some pancakes
3) 70% - 35% = 35% = 0,35 (= 1400 g)
4) 1400 : 0,35 = 4000 g = 4 kg - aswer.
Answer:
15
Step-by-step explanation:
y=21 x 5 = 105
x=3 x 5 = 15
Answer:
x = 8 and x = -3.
Step-by-step explanation:
-x^2 + 5x + 24 = 0 at the x intercepts.
Divide thru by -1:
x^2 - 5x - 24 = 0
(x - 8)(x + 3) = 0
x - 8 = 0 , x + 3 = 0
x = 8 and x = -3.
