Answer:
x = -9.8
Step-by-step explanation:
6(x+7.8) =−12
Divide each side by 6
6/6(x+7.8) =−12/6
(x+7.8) =−2
Subtract 7.8 from each side
x+7.8-7.8 = -2-7.8
x = -9.8
Well 12:2 is apples:loaves or A:L. So 12:2 is equivalent to 6:1 which is also equivalent to 30:5 or 30 apples:5 loaves
So .25 x 1000 is 250 -1000 =750 740 is the answer
X ^ (4/5)
Remember square root is 1/2 power. It has an index of 2 and power of 1. If you can remember this rule you can follow it for any other conversion.
So first lets do the fraction: 68/80. This is probably the most simple part, but if you want to simplify it you could go all the way down to 17/20.
For decimalthen you divide 68 by 80, and that is .85! Then to get your percentage, you multiply it by 100 and end up with 85%.
Percent: 85%
Fraction: 68/80 or 17/20
Decimal: 0.85
Hope this helps!
