In an isosceles triangle, there are two sides that are congruent.

In this case, AB and BC are congruent.

Knowing this, we know that AB = BC

Since we know the values of AB and BC, we can put them into the equation:

3x - 4 = 5x - 10

Subtract 3x from both sides:

-4 = 2x - 10

Add 10 to both sides to isolate 'x':

6 = 2x

Divide both sides by 2:

x = 3

Now that we know the value of the variable, we just have to input it into AB's equation:

3x - 4 = 3(3) - 4

3(3) - 4 = 9 - 4

9 - 4 = 5

<u>AB = 5</u>

Good luck!

Answer:

1 ÷ 6

Step-by-step explanation:

1/6 <em>is</em> a division expression. It means "one divided by six."

The slash (/) can be replaced by the "divided by" symbol (÷), if you like.

1/6 = 1 ÷ 6 . . . . means "one divided by six"

5. A television set is sale at P13,499 in cash or on installment terms, P2,500 each

klio [65]

Cash is always king. It will cost you more if you pay interest, but you may not have enough money to buy this very over priced $13,499 TV. I say shop around for a cheaper TV.

it is given that ln(y+1) - ln(y) = 1+3ln(x) . express y in terms of x in a form not involving logarithms

Rina8888 [55]

$ln( \frac{y + 1}{y} ) = ln( {x}^{3} e) \\ \frac{y + 1}{y} = {x}^{3} e$

A company has made a rubber ball for $0. 02 per square foot. The company wants to spend a maximum of $1 each on a new ball.

Misha Larkins [42]

The diameter of the new rubber ball, to the nearest foot, must be D = 4.0 ft (in the case of the maximum cost).

<h3>How to find the diameter of the ball?</h3>

Remember that for a sphere of diameter D, the surface area is:

A = 4*pi*(D/2)^2

In this case, the cost is $0.02 per square foot, and the company wants to expend (at maximum) $1 per ball, so first we need to solve:

$0.02*A = $1

A = $1/$0.02 = 50

So the surface of the ball must be 50 square feet.

Then we solve:

50ft^2 = 4*3.14*(D/2)^2

D = 2*√(50 ft^2/(4*3.14)) = 4.0 ft
