A large jar contains 500 marbles. All of the marbles in the jar are either blue or yellow, and there are 3 times as many blue ma
rbles as yellow marbles. Which equation can be solved to find the number of yellow marbles in the jar?
1 answer:
Answer:
The equation to solve to find the number of yellow marbles =
3y + y = 500
4y = 500
The number of yellow marbles = 125
Step-by-step explanation:
Let the number of
Blue marbles = x
Yellow marbles = y
A large jar contains 500 marbles.
x + y = 500
All of the marbles in the jar are either blue or yellow, and there are 3 times as many blue marbles as yellow marbles.
3y = x
Hence, we substitute 3y for ymx in the above equation
3y + y = 500
4y = 500
y = 500/4
y = 125
The number of yellow marbles = 125

Only the upper-left statement is NOT true.
Answer:
C. (5, -3)
Step-by-step explanation:
4x + 3y = 11
x - y = 8 (multiply by 3) --> 3x - 3y = 24
4x + 3y = 11
3x - 3y = 24
---------------------add
7x = 35
x = 5
5 - y = 8
y = 5 - 8
y = -3
(5, -3)
Answer:
y = [1]x + [-5 ]
Step-by-step explanation:
the equation is : y = ax+b
the slope is a : a =1 ( same slope parrallal to the line : y= x-3 )
the line that passes through (3, -2) : -2 = (3)+b
b = -5
the equation is : y = x-5
