Answer:

For the first image: -0.4/9

Second Image = 1.53/0.45

Step-by-step explanation:

a + b = 1.6 - 2 = -0.4 (The symbols just make it stay negative)

2 - c = 2 - (-7) = 2 + 7 = 9

--------

2a - 1/3 = 2(-3/5) - 1/3 = -1.2 -1/3 = -1.5333

b/15 = -6.75/15 = -0.45

(The two negatives make it positive)

Hope this helps

Answer:

x=1

Step-by-step explanation:

To solve this question we will have to open the bracket first

So let's solve the question

5(2x-8)+15=-15

Bracket first

10x-40+15=-15

We will have to solve the question further

10x-25=-15

Add 25 to both sides

10x=10

Let's make x the subject of formula by dividing both sides by 10

x=1

Therefore x is 1
