Answer:
C
Step-by-step explanation:
5×2=10
10-15x-20
-10-15x
5(-2-3x), or -5(x+4)(x-1) solve it and find your answer
First of all change <span>milliliters</span> to litres.
1500 ml = 1,5 l
Now,
you know that 7,5 l = 100% (the whole amound)
and you are asking how much is: 1,5 l of the whole, so you got:
7,5 = 100%
1,5 = x%
7,5 x = 150
x = 150 / 7,5
x = 20%
Answer: 1500 ml is a 20% of the 7,5 litres.
1000= 10^3 -- ten to the third power
assuming you mean whole numbers,
graba calculator, figure out what
1^3, 2^3 3^3 ... 9^3 are
or
1x1x1
2x2x2
3x3x3
...
9x9x9
Answer:
x = 8/3, y = 22/3
Step-by-step explanation:
5x-y=6-2x+y=8
5x-y=8 --- 1
6-2x+y=8 --- 2
by solving 1 and 2, x = 8/3, y = 22/3
Density = Mass (grams) / Volume (cubic cm)
Density = 5.67g / .835 cc
Density = 6.7904191617 g per cc
1 Cubic Centimeter = 1,000 cubic millimeters
Density = 6.79 g / cc = .00679 g / cubic millimeter
