Let the number of blue marbles be x
number of yellow marbles = x/3
number of green = x- 90
ATQ
x + x/3 + x - 90 = 694
2x + x/3 = 784
(6x + x)/3 = 784
7x/3 = 784
x = 784 x 3/7
x = 112 x 3
x = 336
number of blue marbles = 336
Number is x
3 times of x is increased by 22, that euals 14 less than 7 times x
3x+22=-14+7x
minus 3x both sides
22=-14+4x
add 14 to both sides
36=4x
divide both sides by 4
9=x
the number is 9
Well x will need to equal 70 because if u do 70 x 5 it will be 350 so u will need to divide that by 5x and u will get x=70
Answer:
option D
Step-by-step explanation:
x=-1 and x=-3 are the real zeros
We plug in the x values in each equation and check which equation makes y=0
A) y=x^4-4x^3-4x^2-4x-3
x=-1 , 
x=-3 , 
y is not equal to 0 so option A is not correct
B.y=-x^4-4x^3+4x^2+4x+3
x=-1 , 
x=-3 , 
y is not equal to 0 so option B is not correct
C.y=x^4+4x^3+3x^2+4x-4
x=-1 , 
x=-3 , 
y is not equal to 0 so option C is not correct
D) y=x^4+4x^3+4x^2+4x+3
x=-1 , 
x=-3 , 
y=0 so option D has two real zeros x=-1 and x=-3
So we know that the term we start with is 3. And the next term is going to be 3 times 2, since the question states that each subsequent term is 2 times the term before it.
So then we have the series:
3, 6, 12, 24, 48, 96...
These are the first six terms of the pattern, found by multiplying each term prior by 2.
