Mathematics
1 answer:
Sholpan [36]3 years ago

Answer:

You have to replace x for each density

Step-by-step explanation:

Density = Mass / Volumen

1,000 g = 1 kg

1,000,000 cm^3 = 1 m^3

g/cm^3 = 1000 kg/m^3

Using density as x

volumen \:  =  \frac{50000}{x}  \\ volumen  \: sphere \:  = 4\pi {r}^{3}  \\ 4\pi {r}^{3}  =  \frac{50000}{x}  \\ r =  \sqrt[3]{ \frac{50000}{4\pi {x}^{} } }

( use elimination) on 3x+5y=12 and x-3y=4
Elena L [17]

Answer:

x=4 y=0

Step-by-step explanation:

3x+5y=12

-(x-3y=4)

3x+5y=12

3(-x+3y=-4)

3x+5y=12

-3x+9y=-12

14y=0

y=0

Then, substitute the y into the equation to find x

x-3(0)=4

x=4

Margo freezes 8 cups of strawberries if this is 2/3 of the total strawberries that she picked how many cups of strawberries did
Goryan [66]

Answer:

12 cups.

Step-by-step explanation:

Let x be the total cups of strawberries picked by Margo.

We have been given that Margo freezes 8 cups of strawberries and this is 2/3 of the total strawberries that she picked.

We need to find x such that 2/3 of x equals 8. We can represent this information in an equation as:

\frac{2}{3}x=8

Let us multiply both sides of our equation by 3.

3*\frac{2}{3}x=3*8

2x=24

Let us divide both sides of our equation by 2.

\frac{2x}{2}=\frac{24}{2}

x=12

Therefore, Margo picked 12 cups of strawberries.
