Answer:

350 grams

Step-by-step explanation:

- 6 people = 120

 10 = ?

- this is how like to use ratios

  6 : 120  

  10 : x

- multiply the numbers in a criss-cross fashion

so,  

- multiply 120*10 and devide by the number multiplying with the unknown ( 6 in this case  )

- (120*10)/6 = 350

Answer:

The answer is 350 grams of sugar

Step-by-step explanation:

You use a ratio

\frac{6}{10} = \frac{210}{?}

Compare the numerators. Since  

6 ⋅ 35 =210  ,  multiply the denominator  10  by  35  to get  350

Now see if you can solve these word problems about time and distance.
ladessa [460]

Answer:

3.5 hours

Step-by-step explanation:

Ediburgh -------------------------------350 miles-------------------------London

Let the distance traveled by train from Edin to London be "x"

hence the distance traveled by train from London to Edin would be "350-x"

  • The rate of Edin to London train is 60
  • The rate of London to Edin train is 40

Let the time they meet be"t"

Now, we know distance formula to be D = RT

Where

D is distance

R is rate

and

T is time

<u>Train from Edin to London:</u>

x = 60t

<u>Train from London to Edin:</u>

350-x = 40t

Solving for x:

350 - 40t = x

We put this into first equation:

x = 60t

350 - 40t = 60t

350 = 100t

t = 350/100

t = 3.5

They meet after 3.5 hours
