Solve the equation for x. 2/3x- 1/9x+ 5 = 20

saw5 [17]

Answer:

27 if variable is near the fraction,

-1/129 if variable is in the denominator and not numerator

Step-by-step explanation:

make 2/3 have the same denominator as -1/9

2/3*3/3=6/9

6/9x-1/9x=5/9

5/9x+5 = 20

20-5 = 15

5/9x = 15

15/(5/9x) -> x= -1/129

if you mean the whole equation has the variable x and no the denominator then it is equal to 27

How do you graph y=2sin(x-pi)+1

Semenov [28]

Here's is a graph of that function. The 2 is the amplitude of the graph. Meaning the difference from top to bottom is 2, 3-1 is 2

The +1 moves the whole graph up one unit and the minus pi shifts the whole graph left by a length of pi.

Sam receives the following scores on his English tests: 63, 84, and 96. What average score does he need on the last two tests in

OLEGan [10]

Sam would have to get a 97 on his next test in order to maintain his average score at an 85. This is because if you add up 63, 84, 96, and 97 you get 340. When you divide 340 by the 4 test scores you get an average of exactly 85
