Answer:
The answer to your question is: 11 < pH < 14
Step-by-step explanation:
Data
Bleach have a pH less than 14 and greater than 11.
We have to use these symbols:
< greater than > less than
and pH will be in the middle
11 < pH < 14
This inequality means the Bleach has a pH between 11 and 14
Answer:
5x − 4 = 3x + 8
5x - 4 <em>+ 4</em> = 3x + 8 <em>+ 4</em>
5x = 3x + 12
5x <em>- 3x</em> = 3x + 12 <em>- 3x</em>
2x = 12
2x <em>/ 2</em> = 12 <em>/ 2</em>
x = 6
Answer:
x= -1 and y =7
Step-by-step explanation:
To solve by elimination, multiply the entire first equation by 2 so that your x terms have the same coefficients.
2*(9x+2y=5) becomes 18x+4y=10.
Now stack and add each like term.
18x+4y=10
-18x-3y=-3
----------------------
0x +y = 7
y=7
Substitute y=7 into one of the original equations and solve for x.
9x +2(7) = 5
9x + 14 = 5
9x = -9
x=-1
