Answer:
300 mL
Step-by-step explanation:
If one part is 100 mL, then 3 parts will be 300 mL.
300 mL of water should be added.
Easy,
23y-(7x-2y)+x
<span>There is an imaginary</span> 1 in front of the parentheses, making it,
23y-1(7x-2y)+x
Now, distribute the 1.
-1*7x= -7x
and
-1*-2y= 2y
Leaving your problem looking like...
23y-7x+2y+x
Combine your apples and oranges.....
25y-6x
Thus, your answer.
12. A full turn is 360 degrees. 360 divided by 30 is 12.
| 5x - 6 | = -41....no solution because an absolute value cannot be negative
|7x + 13 | = 27
7x + 13 = 27 -(7x + 13) = 27
7x = 27 - 13 -7x - 13 = 27
7x = 14 -7x = 27 + 13
x = 14/7 -7x = 40
x = 2 x = -40/7
so basically, equation 1 has no solution and equation 2 has 2 solutions
