20 cats * ( 1 bag of food / 5 cats per month ) = 4 bags of food per month to feed all 20 cats
In simplify the expression =
1.56 • 10^52 + 3.5 • 10^48
The work become much simpler if you do it in a table. Hope this helps!!
Step-by-step explanation:
sqrt(5x)×(sqrt(8x²) - 2×sqrt(x)) =
sqrt(5x × 8x²) - 2×sqrt(5x × x) =
sqrt(40x) × x - 2x × sqrt(5) =
2x×sqrt(10x) - 2x×sqrt(5)
therefore, the last option is correct.
$750 / $30 = 25 maths teaching kids
$350 / $25 = 14 maths starter kits
if you wanted to see if it was right, you would just do 14*25 and you would get $350
hope I helped!!
