Answer:
34
Step-by-step explanation:
-5y=-45
y=-45/-5
=9
y=9
then
5y-11=5×9-11
=45-11
=34
Answer:
The money invested in the account 1 was $8,000 and in the account 2 was 12,000.
Step-by-step explanation:
In this case we can formulate a system of equations that could find the amount invested in each account, this is:
Money invested in the account 1 is A
Money invested in the account 2 is B
Eq. 1:
Eq. 2:
Replacing the equation 1 in 2, this is:
Now, we can find A:
The money invested in the account 1 was $8,000 and in the account 2 was 12,000.
length = width + 200m
Perimeter = 1000 (the sum of all the sides)
Perimeter = 2*W + 2* (w+ 200)
P = 2*W + 2*W + 2*200
Replacing the perimeter value
1000 = 2*W + 2*W + 2*200
1000 = 4*W + 400
4W = 1000- 400
w= 600/4
w= 150
______________________
The dimensions
width = 150 m
length = width + 200
= 150 + 200
= 350 m
________________
Answer
Width = 150 m
Length = 350 m
