Write a sentence to compare the populations for each planet using the words 10 times as many.

irina [24]

Answer:

10 times

Step-by-step explanation:

Note : It is given that,

Planet Ruba has a population of 1 million aliens and Planet Zamba has 1 hundred thousand aliens.

We know that,

1 million = 1,000,000

1 hundred thousand = 100,000

If we divide 1,000,000 by 100,000, we can compare the populations of two planets. So, we get :

$\dfrac{1000000 }{100000}=10$

It means that the population of Ruba planet is 10 times that of the Zamba planet.

The ratio of money in Brian's wallet to Colin's wallet one day was 7:2. Brian spent £39 that day. Brian now had £4 less than Col

rosijanka [135]

Answer:

Collin initially have $\£14$

Step-by-step explanation:

Let

x------> money that Brian had initially

y------> money that Collin had initially

we know that

$\frac{x}{y}=\frac{7}{2}$

solve for x

$x=\frac{7}{2}y$ -------> equation A

$x-39=y-4$ ------> equation B

substitute equation A in equation B

$\frac{7}{2}y-39=y-4$

$\frac{7}{2}y-y=39-4$

$\frac{5}{2}y=35$

$y=\£14$
