Answer:

Step-by-step explanation:

To find the cost per ounce, divide the cost by the number of ounces. The cost is $2.72 and the number of ounces is 16, so the cost per ounce is $2.72/16 = 0.17. Multiply the cost per ounce by the amount asked to calculate for, 0.17 x 28 = $4.76

To conclude, the cost of 28 ounces of cereals is $4.76.

Which of the following ordered pairs are solutions to the system of equations below?
Masja [62]

The ordered pair (-1, 6) is the solution to the system of equations.

Step-by-step explanation:

Given equations are;

3x+2y=9     Eqn 1

y=4x+10    Eqn 2

Putting value of y from Eqn 2 in Eqn 1

3x+2(4x+10)=9\\3x+8x+20=9\\11x=9-20\\11x=-11

Dividing both sides by 11

\frac{11x}{11}=\frac{-11}{11}\\x=-1

Putting x=-1 in Eqn 2

y=4(-1)+10\\y=-4+10\\y=6

Solution: (-1, 6)

The ordered pair (-1, 6) is the solution to the system of equations.

Answer:

Photo.

Step-by-step explanation:

A: The graph of the system is all points in the graph that suit 4x-2<y</=-5/2x-2

B: The point (-2,-2) is not included in the solution area. While it suits the second equation, it doesn't suit the first, ruling it out as a possible solution. If you plug in -2 as both y and x in the equation 4x-2>y, you'll get -8>-2, which is false. So, it is not a solution.
