Determine the digits of q from these clues. the first and third digits of q are odd. the second and fourth digits of q are even. the fourth digit is two times the first digit. the first and second digits add to seven. the second and third digits add to nine. the third and fourth digits add to eleven.

3456

Step-by-step explanation:

We are given that a number Q .

We have to find the digits of Q from given information

First digit=Odd

Third digit=Odd

Second digit=even

Fourth digit=even

Fourth digit=2 first digit

First digit +second digit=7

Second digit+third digit=9

Third digit +fourth=11

Substitute the value then we get

Third digit +2 first digit=11

Third digit+2 first digit-(second digit +third digit)=11-9

2 first digit- second digit= 2

first digit +second digit+(2 first digit-second digit)=2+7

3 First digit=9

First digit=3

Substitute the value then we get

3+second digit=7

Second digit=7-3=4

Fourth digit=2(3)=6

Third digit=9-second digit=9-4=5

Therefore, the number Q=3456

25/4

step-by-step explanation:

call segment cd's length x. because dc and ab are parallel, angle acd and cab, so triangles adc and abc are similar and we can set up the equation x / ac = ac / ab, or x / 5 = 5 / 4 and x = 25/4.
