Answer:

? = 5

Step-by-step explanation:

Since the figures are similar then the ratios of corresponding sides are equal, that is

\frac{21}{7} = \frac{15}{x} ( cross- multiply )

21x = 105 ( divide both sides by 21 )

x = 5

That is ? = 5

If the population of a state was 4702644 how many representatives should that state have
WARRIOR [948]
There is not an exact way to answer that question. The number of representatives each state has is determined by the population. However, the total number of house representatives has been capped at 435 since 1913. Currently, the ratio of constituents to representatives is 700,000 to 1. So if you divide the total population by 700,000 you will have an approximation of the number of representatives.

Pamela is 6 years younger than Jiri. The sum of their ages is 78 . What is Jiri's age?
Alona [7]
Let’s make

P = Pamela
J = Jiri

J - 6 = P

P + J = 78

We can replace P with J - 6 because they are the same thing.

J - 6 + J = 78

2J - 6 = 78

2J = 84

J = 42

Jiri is 42 years old.
