Answer:
5 5/7
Step-by-step explanation:
-4•6/7•-5/3
Put the numbers as fractions
-4/1•6/7•-5/3
Rewriting
-4/1 * 6/3 * -5/7
Simplifying the middle fraction
-4/1 * 2/1 * -5/7
Multiply the first two terms
-8/1 * -5/7
Multiplying
40/7
Changing from an improper fraction to a mixed number
7 goes into 40 5 times with 5 left over
5 5/7
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
