Answer:

Her daughters age: 1/2x

Step-by-step explanation:

Let's say Rani's present age is x. Her age is twice the age of her daughter.

So if Rani's age is 20, her daughters age would be 10, because Rani is twice the age of 10; so 10 times 2 would be 20.

1/2(20)=daughter's age

so if you substitute x into 20 because we don't actually know Rani's age, it would be 1/2(x)=daughter's age.

hope this helped :-) <3

Bill was planning a trip to Saudi Arabia. Before going, he did some research and learned that the exchange rate is $1 = 3.7 Riya

Answer:

Option D.

Step-by-step explanation:

Exchange rate from Dollars to Riyal is,

1 Dollar = 3.7 Riyals

Bill wants to exchange $11.60 for which we will use the exchange rate.

∵ 1 Dollar = 3.7 Riyals

∴ 11.60 Dollars = 3.7 × 11.60

= 42.9 Riyals

Therefore, after exchange of 11.6 Dollars Bill will get 42.9 Riyals.

Option (D) is the correct option.

Addition axiom

Here, we want to select the correct option

For the relation;

$AB\text{ + BC = BC + CD}$

Now, we want to select the option that would make us conclude that AB and CD has same length

The correct answer here is that of the addition axiom

It allows us know that for the two quantities to be equal, then since they are added to the same value, then the two must be of the same value to preserve the equality

What is the value of x? Enter your answer as a decimal in the box.

Alexandra [31]

Answer:

$x = 22.5$

Explanation:

Given Sides:

HB = 6
HD = 6+15 = 21
HM = 9
HT = 9 + x

-----------------------------

using all these sides, create similarities equation:

$\frac{HB}{HD} = \frac{HM}{HT}$

$\frac{6}{21} = \frac{9}{9+x}$

$6(9+x) = 9(21)$

$54 + 6x = 189$

$6x = 189 - 54$

$6x = 135$

$x = \frac{135}{6}$

$x = 22.5$
