Answer: 6 large frames and 12 small frames
Step-by-step explanation:
We define the following:
x = number of large frames
y = number of small frames
Make the following equations:
x + y = 18
19x + 9y = 222
Use system of equations to solve. We find the value of x first.
y = 18 - x
⇒ 19x + 9(18 - x) = 222
⇒ 19x + 162 - 9x = 222
⇒ 10x + 162 = 222
⇒ 10x = 60
⇒ x = 6
Find value of y:
6 + y = 18
y = 12
∴ 6 large frames and 12 small frames were purchased.
Answer:
w<6 THE SMALL LINE UNDER THE LESS THAN SIGN IS STILL THERE I JUST CANNOT ADD IT
Step-by-step explanation:
first solve the equation to the right.
-3(2w+1) = -6w-3
now solve the whole equation
-33-w< -6w-3
-w+6w < -3+33
5w < 30
divide the 5 from both sides to simplify
5/5w < 30/5
w < 6
THE ANSWER IS w < 6
