spin [16.1K]

Answer:

196 minutes

Step-by-step explanation:]

2x10 is 20 and if you divide 5/10 its 2 so the 4 in 4/5 is the total of 8 because 10 would mean 5/5 and 20+8=28 so 28x7 is 196

A red, a green, and a pink backback are hanging on hooks in the ckassroom. The total weight of the three backpacks is 32 pounds.
Savatey [412]
We know there are 3 backpacks. So when we add the known values 9 3/4 and 1 3/4, we get 11 1/2. So 32- 11 1/2 will give you the pink backpack weight which is 20 and 1/2 pounds.

At a sporting event, the price for 3 cheeseburgers and 2 cups of lemonade is $14 and the price for 2 cheeseburgers and 4 cups of
crimeas [40]
C= the price of a cheeseburger and l = the price of a lemonade:

3c + 2l=14\\2c+4l=12

Divide the second equation by -2 to begin the process of solving by elimination:

3c + 2l=14\\-1/2\ (2c+4l=12)\\\\3c+2l=14\\-c-2l=-6\\\\2c=8\\c=4

Now that we have c, 4, we can plug it in to one of the equations to find l:

3c + 2l=14\\3(4)+2l=14\\12+2l=14\\2l=2\\l=1

So, each cheeseburger is $4 and each lemonade is $1.  The final answer is:

1 cheeseburger and 2 cups of lemonade would cost $6.

f(x-3)= 2(x-3) +7 = 2x-6+7 = 2x +1
