Hello!

A term is a number that is added. As you can see, all of the numbers in the numerator are added. This means that they are all terms, and as there are three, there are three terms.

A coefficient is a constant that is written as a multiplier of a variable. For example, in 3x, 3 is the coefficient. As you can see, in the denominator, 4 is just a constant term; it is not multiplied. Therefore, this statement is incorrect.

Next, in the denominator, 2 is multiplied by x², so it is a multiplier and coefficient.

As we said before, the numerator has three terms, not two, so this sentence is incorrect.

In the numerator, three is added, and is not a multiplier of a variable, so it is incorrect.

Therefore, our correct statements are the first and third sentences are correct, just as you put!

I hope this helps!

The 982 part seems wrong. Are you sure it isn't 981?

around 436 if I use 981 instead. 982 would give a decimal and that would be kinda weird for a part human.

Step-by-step explanation:

You can divide the 205 by 5 to simplify the ratio down. 205/5 = 41. Then you can multiply by 4 to find then number of boys.

981

So you can add the 5 and 4 together to 9 and then divide 981 by 9 to get 109. Then you can multiply by 4 to get 436.

Hope this helps!

£70 is divided between Natasha, Richard & Stephen so that Natasha gets twice as much as Richard, and Richard gets three time

Korvikt [17]

The share of Natasha is £ 42

Solution:

£70 is divided between Natasha, Richard & Stephen

Total amount = 70

Let the share of natasha be "x"

Let the share of richard be "y"

Let the share of stephen be "z"

Natasha gets twice as much as Richard

x = 2y ------ eqn 1

Richard gets three times as much as Stephen

y = 3z

$z = \frac{y}{3}$ ----- eqn 2

Total amount = 70

share of natasha + share of richard + share of stephen = 70

x + y + z = 70

Substitute eqn 1 and eqn 2

$2y + y + \frac{y}{3} = 70\\\\\frac{6y+3y+y}{3} = 70\\\\10y = 210\\\\y = 21$

Substitute y = 21 in eqn 1

x = 2y = 2(21) = 42

x = 42

Thus natasha gets £ 42
