Answer:
484
Step-by-step explanation:
22 times 22
If my math is right it should be b
If bobby has three more than double the amount of jelly beans that marcus has and if marcus has 30 jelly beans, then bobby will have 63 jelly beans.
Find the value of x when a=1, b=2, y= 3 by using general formula
After replace number in a, b, y we have
3 = 1ax^2 - 2x - 12
x^2 - 2x -15 = 0
x^2 - 5x + 3x -15 = 0
(x^2 - 5x) + (3x -15) = 0
x*(x - 5) + 3*(x - 5) = 0
(x - 5)*(x + 3) = 0
x - 5 = 0 or x + 3 = 0
x=5 or x=-3
Answer:
3/7 x +5=8
move 5 to the other side
3/7 x= 8-5
3/7 x= 3
then move 7 to the other side it's sign is ÷ it will be ×
then 3x=3×7
3x=21
then move 3to the other side it's sign is × it will become ÷
x= 21/3
x= 7
