You can multiply both sides by a number that will get rid of the denominators. For ex. you can multiply the first equation by 12 because 4 and 3 both go into 12 evenly. MAKE SURE YOU MULTIPLY THE OTHER SIDE BY 12 AS WELL! Therefore, 12(x/4) - 12(y/3) = 12(1), or 3x - 4y = 12
Answer:
B
Step-by-step explanation:
Answer: x= 5 and y= -2
Step-by-step explanation:
Answer:
(a) 85m
(b) 61cm
Step-by-step explanation:
(a) We know that the formula for the perimeter of a rectangle is 
, where a is the length and b is the width, or vice versa. So for this garden, 
(m)
(b) We know that the formula for the area of a rectangle is 
, where L is the length and W is the width. Note that these values are interchangeable, e.g. 2*3=3*2=6. So for this window,
(cm)
