Answer:

$x=11$

Step-by-step explanation:

Stephanie is $x$ years old.

Tobie is $2x$ years old.

Ulrika is $2x-3$ years old.

$x+2x+2x-3=52$

Marla is making 2 liters of cherry lemonade, 5 deciliter dog limeade and 2,500 milliliters strawberry lemonade for a party after

Nata [24]

→Answer:

3.2 liters of lemonade were consumed during the party.

→Step-by-step explanation:

What we know

_____________________________________

Well there is 2,500 mL of strawberry lemonade

There are 2 liters of cherry

There are 5 deciliters of dog limeade

_____________________________________

So the 5 deciliters of dog limeade doesn't count because it is limeade, not lemonade.

The question is asking for the number of liters so we need to convert the 2,500 milliliters of lemonade to liters.

Which will be 2.5 liters of lemonade.

There are also 2 liters of cherry lemonade so 2.5 + 2 is 4.5.

So if 1.3 liters were left over doing 4.5 - 1.3 we get 3.2, meaning 3.2 liters of lemonade were consumed during the party.

Find the error & explain why it is wrong:

olga nikolaevna [1]

$( { \frac{4 {x}^{3} }{ {y}^{4} }) }^{ - 2} = \frac{16x {}^{6} }{ {y}^{8} }$

$\frac{(4 {x}^{3})^{ - 2} }{ { {(y}^{4} )}^{ - 2} } = \frac{16 {x}^{6} }{ {y}^{8} }$

$\frac{ {16x}^{ - 6} }{ {y }^{ - 8} } = \frac{ {16x}^{6} }{ {y}^{8} }$

The power of -2 was mistook as 2.

12u–9u–5u+13= -5 find u

NikAS [45]

To solve this, we combine like terms. Our equation becomes:

-2u + 13 = -5

Now to subtract both sides by 13 to find that:

-2u = -18

Finally, we divide both sides by the coefficient and find that:

u = 9
