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

I need to solve for x, help please.
BaLLatris [955]

Answer:

x = 52   i hope this helps!   :)

Step-by-step explanation:

so first you gotta realize that every triangle has an interior angle measurement sum of 180 degrees

so we are given 3 angles   74 degrees  x + 2  and x

we now are going to put this into an equation   74 + x + 2 + x = 180

now lets combine like terms to get   76 + 2x = 180

then we are going to subtract the 76 from both sides   2x = 104

now lets divide both sides by 2   x = 52

so x = 52

we can plug in the value of x into both of the other equations to find the angle measurement

52 degrees

52 + 2 = 54 degrees

and then we have 74 degrees

add the 52, 54, and the 74 to make sure it is equal to 180 degrees

106 + 74 = 180

so yes, x does indeed equal 52 degrees
