Answer:

x = -2

Step-by-step explanation:

The segments described in the question are equidistant (meaning they are the same length). Therefore, using algebraic techniques, we can set these two equal to each other and solve for x.

4x - 8 = 6x - 4 Combine like terms by subtracting 6x from both sides.

-2x - 8 = -4 Combine like terms by adding 8 to both sides.

-2x = 4 Divide by -2 on both sides of the equation.

x = -2

Answer:

$w= 37$

Step-by-step explanation:

The student used the wrong property of equality.

When you undo a number to get a letter by itself, you should do the opposite operation of the number said. The student subtracted 15 from 22 instead of adding 15 to 22.

Use the addition property of equality to isolate w.

$w(-15+15)=22+15\\w=37$

If a condominium is purchased for Php 5,700,000.00 and the bank requires 30% down payment, how much is the mortgaged amount?

Darya [45]

We are given that the condominium cost Php 5,700,000.00 and a down payment was made. Since the down payment was 30% of the total cost, therefore we can conclude that the mortgage amount is 70% of the total cost. Hence:

70% = 0.70

mortgage amount = 5,700,000.00 * 0.70

mortgage amount = 3,990,000.00

Answer:

Php 3,990,000.00
