Answer:20 pieces
Step-by-step explanation:
8 7/8=71/8
71/8 *4/7(reciprocal of 1 3/4)= 284/56= 20.2867
The answer would be $100. Equation is 2(m+20)=240.
Hope this helped you.
Add the two equations:
2x + 4y = 16
-2x - 3y = -6
2x + -2x = 0
4y -3y = y
16-6 = 10
When you add the equations you get y = 10
Now you have a value for y, use the first equation to solve for x:
2x + 4(10) = 16
2x + 40 = 16
Subtract 40 from both sides:
2x = -24
Divide both sides by 2
X = -12
Answer: x = -12 and y = 10
