You must combine like terms.
First add 7m and -13m which makes -6m. That makes the equation
-6m - 5 =25.
Then add 5 on both sides, which makes -6m = 30.
Finally divide -6 on both sides and the answer will be
m= -5

You subtract 7m and 13m which would give you -6m after you have -6m - 5= 25 then you add 5 which gives you 30 you then you divide that by -6 which gives you m=-5

Anettt [7]

To determine the amount of juice you will need you will multiply the number of students by how much juice each student will get. This is the idea of grouping. We will need 30 groups of 12 ounces.

30 x 12 = 360 ounces.

You will need 360 ounces of juice.

Which values of m and b will create a system of equations with no solution? choose 1 options.

hichkok12 [17]

Answer:

The graph of a linear equation is a straight line. The "solution" to a system of two linear equations is the point where the two lines cross. If the two lines are parallel, they never cross; hence parallel lines have no solution. Two lines are parallel if they have the same slope (the m value in y = mx+b). One of your equations is y = -2x + (you left the y-intercept out). The slope is -2. So any line with a slope of m = -2 will be parallel to this line and will not cross it. The second line also needs a different value of b, the y-intercept. Otherwise it is the same line and every point is a solution. So if your equation is:

y = -2x + 1

Then any equation of the form y = -2x + b, b≠1 will create a system with no solution. Hence the values of m and b are m = -2, b ≠ 1.
