Answer:
The Equation is
4x+2y= 200
Then total number of candy bars is
X+Y
Step-by-step explanation:
Shelby made $200 from selling x at $4 each and y at $2 each.
Let's have in mind that x is the number of large candy bars
And y is the number of small candy bars
The equation is simple
The amount it was sold is going to be the coefficient of the numbers we don't Know...
So
Equation is
4x+2y= 200
Then total number of candy bars is
X+Y
Answer:
first get the total ratio; 2 + 5 = 7
so the fraction of blue marbles is 5/7
then assume the number of total marbles to be k
then use the expression;
5/7*k = 65
7*5/7 * k = 65*7
5k =455
5/5k = 455/5
k = 91
then calculate the number if red marbles from;
x = 2/7*91
x = 26
Therefore there are 26 red marbles.
Answer:
C.)
Step-by-step explanation:
There are multiple technical ways to explain this but the best one that works for me is the "vertical line test" can be used to find a function or non function. All you have to do is position your pencil vertically, place it to the far left of the graph drag it horizontally across to the right side of the graph. If your pencil is making contact with two lines at one time, it is NOT a function. Hopefully this makes sense.
