Answer:
x= -1/2
Step-by-step explanation:
1. Create an equation
8x+4=0
2. Subtract 4 from both sides of the equal sign
8x = -4
3. Divide 8 from both sides of the equal sign to get x by itself
x= -4/8
4. Simplify
x= -1/2
2 2/5 = 5/5+5/5+2/5 or 12/5
<span>to change a fraction to a decimal you use a calculator of you change it to a fraction then to a decimal
if you multiply a fraction by its recipricol (the number fliped upside down) the you will get 1 so if you multiply 1/2 by 2/1 then you will get 1
</span>
so you multiply 12/5 with 100/x=1200/5x=240
you change the percent to a fraction by moving the decimal place two places to the left or divide it by 100
so 240%=2.4 answer
