<u>Answer:</u>
- 2n + 12 = 100 (Equation)
- 2n = 88 (Solving)
- n = 44 people bought muffins at the bake sale. (Solving)
<u>Step-by-step explanation:</u>
- 100 muffins, and 2 in each package. Therefore, there are 50 packages. However, in the end, there are 12 left, so there must have been 6 packages left.
THE CORRECT OPTION IS A where the input data is correct
Answer:
b
Step-by-step explanation:
Answer:
b=2
Step-by-step explanation:
we have
9x+12y=21 -----> equation A
6x+8y=7b ----> equation B
we know that
If the system of equations have an infinite number of solutions then the equation A must be equal to the equation B
Multiply equation B by 1.5 both sides
1.5*[6x+8y[=7b*1.5
9x+12y=10.5b ----> equation C
Compare equation A and equation C
9x+12y=21 -----> equation A
9x+12y=10.5b ----> equation C
For the equations to be equal it must be fulfilled that
21=10.5b
solve for b
b=21/10.5
b=2
