There are 765 marbles in a box. There are twice as many blue marbles as green marbles. There are three times as many red marbles

Digiron [165]

B=blue
g=green
r=red
2 times as many blue as green
b=2g
3 times as many red as blue
r=3b
subsitute 2g for b
r=3(2g)=6g
r=6g

r+g+b=765
so we subsitute
r=6g
g=g
b=2g

6g+g+2g=765
add like terms
9g=765
divide both sides by 9
g=85
subsitute
b=2b
b=2(85)
b=170

170 blue

PLS HELP I DONT UNDERSTAND!! What type of circle would you use when graphing x≥5

inna [77]

How to:

When graphing a linear inequality on a number line, use an open circle for "less than" or "greater than", and a closed circle for "less than or equal to" or "greater than or equal to".

For this problem:

For the number line, we would place a solid dot at −5 because the value is both greater than and equal too (≥) and then continue a line on the number line to the right of that point incorporating all values greater than −5

Answer:

(image attached) 

Look at the one showing your problem, the first one.

It's reverse of that since X is greater meaning the line goes the other way instead as shown in the second image.
