If 10 cookies cost $2.00, how much will 25 cookies cost? Thank you!

IgorLugansk [536]

So, if 10 cookies cost 2 dollars multiply that by 2 to get 20 cookies ( 4 dollars )
Then divide 2 in half because you need 5 more cookies to get the total 25.
( 1 dollar. )

So that will cost 5 dollars! I did the math myself.

I hope this helped!

I would appreciate it if you gave me a Thanks and a brainliest (:

$f(x) = (x - -10)(x - -2)$

We could stop here and have answered the question.

$f(x) = (x+10)(x+2) = x^2 + 12 x + 20$

Answer: $f(x)=x^2+12x + 20$

The planet venus is on average 2.5x10^7 kilometers from earth. The planet mars is on average 2.25x10^8 kilometers from earth. Wh

umka21 [38]

Answer:

The average distance from venus to mars is 2.5x10⁸ kilometers.

Step-by-step explanation:

We know:

d₁: average distance between venus and earth = 2.5x10⁷ km

d₂: average distance between mars and earth = 2.25x10⁸ km

We can find the average distance from venus to mars as follows:

$d_{t} = d_{1} + d_{2}$

First, we need to equal the base power 10 so we can sum both distances:

$2.25 \cdot 10^{8} = 2.25 \cdot 10^{7} \times 10 = 22.5 \cdot 10^{7} km$

Now, average distance:

$d_{t} = 2.5 \cdot 10^{7} + 22.5 \cdot 10^{7} = (2.5 + 22.5) \cdot 10^{7} = 25 \cdot 10^{7} km = 2.5 \cdot 10^{8} km$

Therefore, the average distance from venus to mars is 2.5x10⁸ kilometers.

I hope it helps you!
