Answer:
first option
Step-by-step explanation:
solving the inequality
- 13 > - 5x + 2 > - 28 ( subtract 2 from each interval )
- 15 > - 5x > - 30
divide each interval by - 5 , reversing the symbols as a result of dividing by a negative quantity.
3 < x < 6
since the symbol is < then end values will be an open circle with the values between shaded blue, that is the first graph

Answer:</h3>
<h3>C. In x = -7 </h3>
<h3>
Step-by-step explanation:</h3>
<h3>13 + Inx = 6</h3>
<h3>1. Subtract 13 from both sides</h3>
13 + Inx - 13 = 6 -13
<h3>2. Simplify </h3>
= In x = -7
<h3>Solution : </h3>
<h3>= In x = -7</h3>
Answer:
£152.
Step-by-step explanation:
We have been given that a bottle contains 255 coins. 1/3 of the coins are £1.00.
Let us find 1/3 of 255 to find the number of £1 coins.

This means we have £85.
We are also told that 110 of the coins are 50 p coins.


Let us figure out number of 20 p coins by subtracting the number of £1 coins and 50 p coins from 255.





Now let us find total value of the coins contained in the bottle by adding the values of £1 coins, 50 p coins and 20 p coins.


Therefore, the total value of the coins contained in the bottle is £152.
