The equation is:
12.99 + 2.10b = 21.39
Subtract 12.99 from each side to get:
2.10b = 8.4
Then divide to find the amount of bottles:
b = 4 bottles
Hope this helps!! :)
Answer:
210
Step-by-step explanation:
Divide 120 by 4 and get 30 and multiply 7 by 30 and you get 210
24.31 ÷ 2.6 = 243.1 ÷ 26 = 9.35
Answer:
C. 
Step-by-step explanation:
One is asked to find which inequality has (
) in its solution set. Remember that an inequality is another way to represent a set of solutions. In essence, it states that all numbers less than; less than or equal to; greater than; or greater than or equal to, are a part of the solution. One simplifies an inequality in a similar manner to how one simplifies an equation, by using inverse operations and simplification. Just note that when multiplying or dividing the inequality by a negative number, one has to flip the inequality sign to ensure the expression remains true.
Simplify each of the inequalities, then evaluate to see which one has () as a part of its solution set.
A. 
B. 
C.
D. 
As can be seen, option (C ) is the only one that fits this requirement. Since option (C) simplifies down to () or in words, (x) is less than (-2.5). This option is the only one that fits the solution since (-3) is less than (-2.5).
You can use mathpapa for 1,2,3 and 4 :)
