There are 13 green marbles in the bag.
Step-by-step explanation:
Total marbles = 18
Let,
Green marbles = x
Blue marbles = y
According to given statement;
The number of green marbles is 2 less than 3 times the number of blue marbles.
x = 3y-2 Eqn 1
x+y=18 Eqn 2
Putting value of x from Eqn 1 in Eqn 2;
Dividing both sides by 4
Putting y=5 in Eqn 1
There are 13 green marbles in the bag.

Answer:
Triangle
Step-by-step explanation:
The square root of 99 is irrational.
The answer would be 6:15 since it can be divided by two and equal 3:5, i think
I’m pretty sure the equation is 7.50x+20=9.50x+12 then you subtract the x over and now it’ll be -2x+20=12 and then you do 12 - 20 and that is -8 and then -8 divided by -2 and that is 4. so maybe x equals 4? then plug it in and now you have to check your answer so you plug in the 4 and it is 7.50(4)+20=9.50(4)+12 and then that is 50=50. I MAY BE TOTALLY WRONG. but i tried to help at least
Hello from MrBillDoesMath!
Answer:
11
Discussion:
Solution by distance formula:
d = sqrt( (x2-x1)^2 + (y2-y1)^2)
= sqrt ( (-1 - (-1)
)^2 + (4 - (-7))^2 )
= sqrt ( ( -1 + 1) ^2 + (4+7)^2)
= sqrt ( 0^2 + 11^ 2 )
= sqrt ( 11^2)
= 11
Solution by contemplation!
Note the x coordinate of both points is the same (i.e. -1) This means the line joining the points is vertical and its length is simply the difference of the y coordinates: 4 - (-7) = 4 + 7 = 11
Thank you,
