Answer:

Step-by-step explanation:

Use proportions to figure this out. On the top you'll have miles and on the bottom you'll have minutes. I am going to change 3/4 to .75 and 1/8 to .125:

$\frac{miles}{minute}:\frac{.75}{.125}$

We want to know how many miles per 1 minute that is. So we have the unknown on top in a new ratio, with 1 on the bottom:

$\frac{miles}{minute}:\frac{.75}{.125}=\frac{x}{1}$

This second ratio is allowing us to calculate what the decimal ratio is in miles per 1 minute. Cross multiply to get

.125x = .75 so

x = 6 miles

That tells us that the decimal ratio is equivalent to 6 miles per minute

To figure this out just multiply 3/4 by 8 because you need to seethe plane flies 3/4 miles 8 times.

Whould anyone mind helping please. The first box says 6.25x+12x=30.75 the second box says 6.25x+12=30.75 3rd box says 6.25x+30.7

Answer:

The correct equation is: 6x+12 = 30.75

And 3 people went to the movies

Step-by-step explanation:

We will write the equation to represent this scenario.

Let x be the number of people who went for movies.

Then the price of ticket for x people will be: 6.25x

They spent $12 on refreshments and a total of $30.75 so the equation will be:

$6.25x+12=30.75$

solving the equation will give us total number of people

So,

$6.25x+12 = 30.75\\6.25x = 30.75-12\\6.25x = 18.75\\\frac{6.25x}{6.25} =\frac{18.75}{6.25}\\x = 3$

Hence,

The correct equation is: 6x+12 = 30.75

And 3 people went to the movies

morpeh [17]

If Dan is 8x years old next year then he must be 8x-1 years old this year
With the same logic, five years ago from this year, he must be 8x-1-5=8x-6

The answer should be 8x-6

1.In a class of 45 pupils ,21play chess and 23 play cards and 5play both games

Mumz [18]

Step-by-step explanation:

(a)

ii.

21 - 5 = 16 play only chess.

iii.

23 - 5 = 18 play only cards

5 play both.

that is 16+18+5 = 39 that play at least one of these games.

so, 45 - 39 = 6 don't play any of these games.

(b)

we have 16+18 = 34 pupils out of 45 that play exactly one game.

so the probabilty to pick one of them is as usual

desired cases / total cases = 34/45 =

= 0.755555555... ≈ 0.76
