Answer:
1 1/2 x 4 1/2 x 5 = 33 3/4
5y=95
y=95/5(vertically opppsite angles)
5x=85
x=85/ 5(vertically opppsite angles)
Answer:
First number = 33, Second number = -19
Step-by-step explanation:
We can use F to represent the first number and S to represent the second number.
Our two equations then are F + S = 14 and 2F + 3S = 9
We can use substitution:
