Answer:

15

Step-by-step explanation:

5a - 10b = 45

5a - (10×3) = 45

5a - 30 = 45

5a = 45 + 30

5a = 75

a = 15

Answer:

x = 15

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 given angles and equate to 180, that is

3x - 10 + 6x + 5 + 4x - 10 = 180, simplify left side

13x - 15 = 180 ( add 15 to both sides )

13x = 195 ( divide both sides by 13 )

x = 15

kow [346]

Answer:

p > s

Step-by-step explanation:

Given

p \to poncho

s \to scarf

Required

The inequality

From the question, we understand that;

the number of p used is more than the number of s

<em>more than means greater than.</em>

So, the inequality is:

p > s

To represent this on a number line.

First, we identify the position of s (i.e. scarf)

p > s implies that p is any point to the right of s
