Answer:
yes
Step-by-step explanation:
if you distribute the 9 into the parenthesis you get 9y + 45. Therefore, both equations are equivalent seeing that they both equal to 9y + 45.
Answer: I believe the answer is 3.07 but I may be wrong so if you want you can wait for another answer :D
Step-by-step explanation:
First, you want to establish your equations.
L=7W-2
P=60
This is what we already know. To find the width, we have to plug in what we know into P=2(L+W), our equation to find perimeter.
60=2(7W-2+W)
Now that we only have 1 variable, we can solve.
First, distribute the 2.
60=14W-4+2W
Next, combine like terms.
60=16W-4
Then, add four to both sides.
64=16W
Lastly, divide both sides by 16
W=4
To find the length, we plug in our width.
7W-2
7(4)-2
28-2
L=26
We know that It calls for 4 1/4 of flour
We have to multiply
What is 4 1/4 * 3 1/2= 14 7/8
You need 14 7/8 cups of flour to make 3 1/2 batches
Hope this helped!
