Answer:

x = 2

y = 7

Step-by-step explanation:

5x+2y=24 -------------->equ 1

8x+2y=30 -----------> equ 2

equ 1 - equ 2 =====> -3x = - 6

x = -6 / -3 = 2

x = 2

Put x = 2 in equ 1,

5*2 + 2y = 24

10 + 2y = 24

2y = 24 - 10

2y = 14

y = 14/2

y = 7

Answer:

The value of x is 29.

Step-by-step explanation:

→ The angles arent congruent, they are supplementary.

→ Supplementary angles equals 180 degrees.

→ The equation looks look:

$2x - 10 + 4x + 16 = 180$

→ Let's solve the equation.

$2x - 10 + 4x + 16 = 180 \\ 6x + 6 = 180 \\ \frac{ \: \: \: \: \: - 6 = - 6}{ \frac{6x}{6} = \frac{174}{6} } \\ x = 29$

→ Therefore, the value of x is 29.

5. Lines p and q are parallel, and line w is a transversal. Which angle is not congruent to angle 1?

Tamiku [17]

Answer:

∠2, ∠4, ∠6 and ∠8 are not congruent to ∠1.

Step-by-step explanation:

From the picture attached,

p and q are the parallel lines and w is a transversal.

∠1 ≅ ∠3 [Vertically opposite angles]

∠1 ≅ ∠5 [Corresponding angles]

∠1 ≅ ∠7 [Alternate exterior angles]

Therefore, ∠2, ∠4, ∠6 and ∠8 are not congruent to ∠1.
