Answer:

x < 3 and x < -4

Step-by-step explanation:

We start by solving 2x + 1 < 7

2x + 1 < 7

2x < 7 - 1

2x < 6

x < 6/2

x < 3

Then we solve -2x + 1 < 9

-2x + 1 < 9

-2x < 9 - 1

-2x < 8

Dividing by -2 on both sides gives;

x < -4

The cost of a ticket increases by 10% to £18.15 Work out the original cost.

Licemer1 [7]

Answer:

£16.50

Step-by-step explanation:

$x \times (1+\frac{10}{100} )=18.15$

$x \times \frac{110}{100} =18.15$

$\frac{110}{100} x=18.15$

$1.1x=18.15$

$\frac{1.1x}{1.1}=\frac{18.15}{1.1}$

$x=16.5$

3) There are 35 people living in poverty and 42 people not living in poverty

REY [17]

Answer:

John is not correct

Step-by-step explanation:

(Unless you meant 5:6)

Make the base question into $\frac{35}{42}$

simplify as much as possible. I found the Greatest Common Denominator (GCF) of 35 and 42, which was 7

divide 35 and 42 by the GCF (7), and you should get 5:6 as your answer.
