y = 30x + 75
Step-by-step explanation:
every month you're paying 30 dollars for a fee.
the 75 dollars is simply the "down payment" so to say.
m is the constant growth or the continuous growth or the charge per month.
31 units
the outer part,try to combines pieces that would make one unit and count
9x-7= 29
9x-7+7= 29+7
9x= 36
Divide by 9 for 9x and 36
9x/9= 36/9
x= 4
Check answer by using substitution method
9x-7= 29
9(4)-7=29
36-7= 29
29= 29

Answer:
Length 100 m, width 85 m.
Step-by-step explanation:
If the perimeters are equal then the sum width + length has to be the same as 70 + 115 = 185.
The area of the given field = 115 * 70 = 8050 m^2.
Lets try length 100 and width 85 .This gives an area of 8500 so that would fit.
hope this helped pls see the comment i gave to u about my question help a friend thx :)
