Layla and Jacob are taking a photography class. Layla took twice as many photos as Jacob, and Jacob took 10 fewer photos than La

yla. This situation can be represented with the system y = 2x and y = x +10, which can be used to find the number of photos taken by Jacob x and the number of photos taken by Layla y. Solve using systems of equations by substitution

Answer:

x = 10; y = 20

Step-by-step explanation:

y = 2x

y = x +10

Substitute y of the second equation with 2x.

2x = x + 10

x = 10

y = 2x = 2(10)

y = 20

Answer: x = 10; y = 20

Can anyone help with this
mestny [16]
The sum of the interior angles of a triangle is always 180 degrees.  Thus,
the sum of 31, x+4 and 3x+9 must be 180.

31 + x + 4 + 3x + 9 = 180,     or    44 + 4x = 180


While it's not necessary, y ou could reduce this equation before solving for x:

11 + x = 45.             Then x = 34 degrees.

The three angles are then:

31
34+4 = 38
3(34) + 9 = 111

Check:  show that 31+38+111 = 180 (degrees)
