Can y’all help me on part b

Part A.   B. 4(240 + p)  = 1860.

Part B.   225 pages.

Step-by-step explanation:

Part  A.

It's 4 times the number of pages read by both Jennifer and Nelson

So the equation is :

4(240 + p)  = 1860..

Part B.

Solving for p:

4(240 + p)  = 1860.

960 + 4p = 1860

4p = 1860 - 960

4p =  900

p = 225.

Part A : Option B

Part B : p = 225 pages

Step-by-step explanation:

Let,

Marty's pages be M

Nelson's pages be N

Jennifer's pages be J

It is given that Marty read 4 times as many pages as Nelson & Jennifer Combined. Expressing this mathematically:

M = 4 x (N + J)

M = 4(N+J)

given that M = 1,860 and N = 240, substituting this into the above equation:

1,860 = 4(240 + J)

it is also given that Jennifer's number of pages is p,

hence Jennifer's pages J = p, hence the equation becomes:

1,860 = 4(240 + p) > option B

Part B,

solving the last equation:

1,860 = 4(240 + p)  (rearrange)

4(240 + p) = 1,860  (divide both sides by 4)

240 + p = 1860 / 4

240 + p = 465 (subtract 240 from both sides)

p = 465 - 240

p = 225

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
