42×2/3=28
42×1/3=14
28+14=42

Let, the original money in Malika's account = x
Grandparent's money = 0.25x = 282
x = 282 / 0.25
x = $1128
So, Father's money = 1128 × 0.15 = $169.2
Now, Total Money in her account would be: 1128 + 282 + 169.2 = $1579.2
In short, Your Final Answer would be $1579.2
Hope this helps!
Answer: B
Begin by simplifying the given equation, so it's rearranged into standard form. Move all the terms onto one side, so they equal 0. This would result with
-3x-9=0. Quadratic formula is (-b±√(b²-4ac))/(2a). Standard form follow this variable format:
+bx+c. Use the numbers that correspond with each variable to substitute them into the quadratic formula. This would be
(-(-3)±√(-3²-4(4)(-9)/2(4).
27 i believe
you would substitute y with 0 to find x then you would put 9 in for x to find y then you would go back to the first equation and put -19 in for y and then solve for x and get 27
