1.is 1400 and 2 is b your welcome

Answer 2

$\bf \: solution \: 4th :$


Carrie has 140 coins.
She now has 10 times of the coins she had last month.
Number of coins she had in last month = (To be calculated)
Let it be x.

We can make an equation as following...

$10 \times x \: = \: 140 \\ \\ x = \frac{140}{10} \\ \\ x = 14$

So, she had 14 coins in last month.

$\bf \: solution \: 5th :$

(b) (7 × 20) + (7 × 4) is the correct option.

But how?

Let us see...

From the given information, we can conclude that the equation should be equal to 24 × 7.

So, let us check that (b) is correct or not.

(7 × 20) + (7 × 4) = 7 × 24

Taking 7 as common we get,

7(20 + 4) = 7 × 24

7(24) = 7 × 24

7 × 24 = 7 × 24

Hence proved.

If any doubt, please ask ;)
