Answer:
72
Step-by-step explanation:
- Y/6=12
- Y=6*12=72
Answer:
Step-by-step explanation:
99x - 44y = -605
-99x + 63y = 738
19y = 133
y = 7
-9x + 28 = 55
-9x = 27
x = -3
(-3, 7)
The coefficient (letter chosen) that is used does not matter as it is only to show that it is an unknown variable, if you have more than one variable you need more than one type of coefficient (use different letters for different ones you dont know).
7x-3y=15 is the equation in standard form.
First off, she should consider that there are 12 inches in every foot, that the length and width will increase by a factor of 12, also that the area will increase by a factor of 144.
