Well, first they're assuming that the m<ABC = 90

The value of m<ABC is not given, so they aren't allowed to make up values based on the way the picture looks.

It is given that BD bisects <ABC, which means it splits the angle evenly..

Giving this equation: (x-5) = (2x-6)

Solving for x

-5 + 6 = 2x - x

1 = x

The sum of 5 consecutive integers is 100. What is the first number in this sequence?

yanalaym [24]

So we can call first number "n"

Then all five integers would be n, n+1, n+2, n+3, n+4

So sum of them would be 5n + 10 = 100

Now you can solve for n:

5n + 10 = 100

5n = 90

n = 18

Verify: 18 + 19 + 20 + 21 + 22 = 100. All good.

So answer is 18

Solve the problem making a chart. A Roman statue is three times as old as Florentine statue. One hundred years from now the Roma

Paraphin [41]

Answer: 300 years

Step-by-step explanation:

Let x be the age of Florentine statue,

Thus, According to the question,

The age of Roman statue = 3 x

After 100 years, the age of Florentine statue = x + 100

And, the age of Roman statue = 3x + 100

Again according to the question,

3x + 100 = 2( x + 100)

3x + 100 = 2x + 200

3x - 2 x = 200 - 100

x = 100

Therefore, the present age of Roman statue = 3 × 100 = 300 years
