The number that completes the system of linear is 4
Answer: x=11/36
Step-by-step explanation:
Step One-Subtract 1/6 from both sides.
2x+1/6-1/6=7/9-1/6
2x=11/18
Step Two-Divide both sides by 2.
2x/2=11/18/2
x=11/36.
My math might not be correct, sorry if it is. In addition, my explanation is a bit confusing, so sorry about that too.
The correct answer is C. A 2-column table with 3 rows. Column 1 is labeled x with entries negative 5, 0, 3. Column 2 is labeled y with entries negative 18, negative 2, 10.
Explanation:
The purpose of an equation is to show the equivalence between two mathematical expressions. This implies in the equation "–2 + 4x = y" the value of y should always be the same that -2 + 4x. Additionally, if a table is created with different values of x and y the equivalence should always be true. This occurs only in the third option.
x y
5 -18
0 -2
3 10
First row:
-2 + 4 (5) = y (5 is the value of x which is first multyply by 4)
-2 + 20 = -18 (value of y in the table)
Second row:
-2 + 4 (0) y
-2 + 0 = -2
Third row:
-2 + 4 (3) = y
-2 + 12 = 10
Answer:
He can type 256 words in 4 minutes
Step-by-step explanation:
2 minutes 30 seconds is 2.5 minutes
The rate is the number of words divided by the time
160 words / 2.5 minutes =64 words per minute
We need to find how many words in 4 minutes
Take the rate time the time
64*4 =256
He can type 256 words in 4 minutes
