Answer: an arithmetic sequence
Step-by-step explanation:
Answer:
The total of 4 cups lasts 8 days to Mr. Simpson.
Step-by-step explanation:
The 1/2 cups of food lasts 1 day
⇒ 1 cup of food lasts =
= 2 days.
Now, Mr. Simpson has 4 cups.
So, 4 cups last him = 4 x 2 days = 8 days
Hence, a total of 4 cups lasts 8 days to Mr. Simpson.
Step-by-step explanation:
14 - 10 1/6
14 - 10.16
= 3.84
Given the system of equations:

To solve it by substitution, follow the steps below.
Step 1: Solve one linear equation for x in terms of y.
Let's choose the second equation. To solve it for x, add 3y to each side of the equations.

Step 2: Substitute the expression found for x in the first equation.

Step 3: Isolate y in the equation found in step 2.
To do it, first, add 48 to both sides.

Then, divide both sides by 15.

Step 4: Substitute y by 5 in the relation found in step 1 to find x.

Answer:
x = -9
y = 5
or (-9, 5)
Also, you can graph the lines by choosing two points from each equation, according to the picture below.
