there are 765 marbles in a in a box. there are twice as many blue marbles as green marbles. there are 3 times as many red marbles as blue marbles, how many red marbles in the box

Answers

let the no. of green marbles be x
no of blue marbles = 2x
no of red marbles = 3*2x = 6x
total marbles = 765
so, x+2x+6x = 765
or, x = 765/9 = 85
no of red marbles = 6*85 = 510

I think it is 120

The total of the shape is 180 so it telling us to take away 1/3 of it so 60 away from 180 is 120

X + 1/7 = 5/14 what is the sum of x and what are the steps?

Answers

$x + (1)/(7) = (5)/(14)$

First, subtract $(1)/(7)$ from both sides.
$x = (5)/(14) - (1)/(7)$
Second, find the LCD of the two fraction.
Multiples of 14: 14
Multiples of 7: 7, 14
The LCD is 14.
Third, make the denominators the same as the LCD.
$(5)/(14) - (1x2)/(7x2)$
Fourth, multiply 1 × 2 to get 2 and 7 × 2 to get 14.
$(5)/(14) - (2)/(14)$
Fifth, combine the denominators.
$(5-2)/(14)$
Sixth, subtract 5 - 2 to get 3.
$(3)/(14)$

Answer as fraction: $(3)/(14)$
Answer as decimal: 0.2143
