Answer: I think it’s c
Step-by-step explanation:(don’t worry I’m a idiot too)
10 1/2 ft=2x-18 in
convert ft to in--10 1/2ft=126 in
126=2x-18
2x=144
x=<em>72 inches or 6 feet</em>
Answer:
He's correct.
Step-by-step explanation:
As long as there is no change in sign of the variables.
Make 2 equations one for the price and one for quantity. so first set x = AA and y= AAA. for price 37= 1x+.75y. now for the quantity we have x+y=42. Now we can solve by subtracting the equation for price from the equation for quantity and we get .25y =5. solving this we get y= 20. Now we plug that value back in and solve for x. 22 double A's and 20 triple A's.
