Answer:

Jerry collected 126 stamps.

Renee collected 487 stamps.

Step-by-step explanation:

Let Jerry be J and Renee be R

Eq1: R=4J-17

Eq2: 613=R+J

Rearrange the second equation to isolate J:

J=613-R

Sub this new equation into Eq1 and solve for R:

R=4(613-R)-17

R=2452-4R-17

5R=2435

R=487

Sub R=487 into Eq2 to solve for J

613=487+J

J=126

In the accompanying diagram of parallelogram ABCD,diagonals AC and DB intersect at E, AE = 3x - 4, andEC = x + 12.What is the va
skelet666 [1.2K]

x = 8

Explanation:

AE = 3x - 4

EC = x + 12

SInce diagonals AC and DB intersect at E

it means the lines which meet at the intersection E are equal. A and C meet at E which gives AE and EC

AE = EC

3x - 4 = x + 12

collect like terms:

3x - x = 12 + 4

2x = 16

divide both sides by 2:

2x/2 = 16/2

x = 8

on a number line, point D is located at 9 and point P is located at -11 what is the distance from d to p
Aleks04 [339]

Answer:

20

Step-by-step explanation:

The distance between two points on the number line is the absolute value of the difference of their coordinates.

coordinate of point D: 9

coordinate of point P: -11

Take the absolute value of their difference. It does not make a difference in which order you subtract the coordinates.

distance = |-11 - 9| = |-20| = 20

Answer: The distance is 20.
