Both ABC and 3D8 are three digit numbers such that ABC - 3D8 = 269. If 3D8 is divisible by 9, what number does ABC represent?

1 answer:

3 0

3D8 is divisible by 9 ⇒ sum 3+D+8 is divisible by 9
⇒ 11+D=18, D=18-11, D=7
⇒ 3D8= 378
abc - 378 = 269
abc= 269+378
abc= 647

QRST is a rectangle. If RT = 4x – 16 and SQ = x + 5, find the value of x.

igor_vitrenko [27]

Answer:

Step-by-step explanation:

Q R

T S

I put the letters here in order, a clockwise order starting at Q.

If you look at our diagram you will see that RT and QS are actually the diagonals of this rectangle.

The diagonals of a rectangle are congruent.

We have the measurement of RT = the measurement of QS.

That is we have this equation: 4x-16=x+5.

4x-16=x+5

Subtract x on both sides:

3x-16= 5

Add 16 on both sides.

3x = 21

Divide both sides by 3.

x = 7
