Yeah, dude it sure is.
I'm assuming you wanted something like this?
40x + 4.5y = 112
x = Days
y = Pairs of shoes
112 = Total profits
Yes, it is reasonable for Brittany to think that she will need more than 2 batches of cookies to feed all of the people at her school.
One batch of dough makes 2 dozen cookies, or 24 cookies.
This means that two batches of dough makes 4 dozen cookies, or 48 cookies.
If Brittany only brought 48 cookies to school, some kids wouldn't get cookies. So, we know that Brittany should probably bake more than 2 batches of cookies.
Answer:
Carla ran 0.1 miles per minute.
Step-by-step explanation:
To solve this, we need to use the distance formula.
The formula is d=rt, where d is the distance traveled, r is the rate in which the distance is traveled, and t is the amount of time it took to go that distance. So lets plug it all in.
d=rt
3=(r)(30)
Now, we need to do the inverse of multiplying 30 to both sides, which would be the same as dividing by 30 on both sides.
3/30=(r)(30/30)
0.1=r
The rate is 0.1. Carla ran 0.1 miles per minute.
Answer:
I'm pretty sure it would be 345, just add the two 178 and 167
X + y = 19
10x + 4y = 100
This is a systems of equations.
Isolate x from the first equation:
x = 19 - y
Now, plug it into the second:
10(19 - y) + 4y = 100
190 - 10y + 4y = 100
-6y + 190 = 100
-6y = -90
y = 15
Plug y in and solve for x:
10x + 4(15) = 100
10x + 60 = 100
10x = 40
x = 4
