Answer:
4m +3 marbles does Helena have in all.
Step-by-step explanation:
Here, m represents the marble in each bag.
She put them in 4 bags with m marbles in each bag.
In each bag she have m marbles
then, in 4 bag she have 4m marbles
⇒total number of marbles= 4m
Since, she had 3 marbles left over.
⇒She have total number of marbles = 4m + 3
Therefore, 4m +3 marbles does Helena have in all.
It's 2.7 pounds because I set up a proportion of 150 over 90 = 4.5 over X and multiplied 90 * 4.5 divided by 150
Answer:
7500. There are 100 centimeters in a meter therefore 75 meters have 7500 centimeters.
The inequality that represents the graph in the box is
Given :
The graph of the linear inequality
Lets pick two points from the graph to frame the linear equation
Slope intercept form of the equation is
Where m is the slope and b is the y intercept
y intercept is (0,6) from the graph
so b=6
Now we find out slope m using formula
Pick two points (0,6) and (2,0)
m=-3
So the equation is
Now we check the inequality sign by testing any point on shaded area
lets pick (4,0)
lets plug in 4 for x and 0 for y
The inequality for the given graph is
we cannot use >= sign because we have dotted lines
