Answer:
x= -15/2 y=-33/2
Step-by-step explanation:
i dont know how you want to solve it but if it is "system of equations" then first solve for the first variable in on e of the equations, then substitute the result into the other equation.
Suppose the length is 7x, the width is then 3x
7x*3x=525
21x²=525
x²=25
x=5
so the length is 7*5=35, and the width is 3*5=15
27+ 2/5×-1/2 = 27 - 1/5
(135 - 1)/5 = 134 /5 <——answer
Answer:
Step-by-step explanation:
Arithmetic sequence
Tn = a+(n-1)d
= -85 +(601-1) 1/6
= -85 + 600/6
= -85 + 100
= 15
601th term is 15
