Answer:

Raspuns corect: b)

Step-by-step explanation:

a4b=24, a×4×b=24⇒a×b=6

perechile de numere cu produsul 6 sunt: {1,6} si {2,3}

a4b in baza 10=100a+40+b

100×1+40+6=146

100×6+40+1=641

100 ×2+40+3=243

100×3+40+2=342

146+641+243+342=1372

Answer:

for 18 x is 6 and for 20 it is 11

Step-by-step explanation:

For 18, since -1+2x and 5+x is the same thing, set up and equation. WE can simplify to -1+x=5 and then we get x=6

For 20, 18 is 11 since 18=-4+2x. If we simplify we get 22=2x then we can use algebra to say that x=11

Hope this helps :)

Parallelogram Property: opposite angles are congruent Solve for x

Anna11 [10]

Answer:

Step-by-step explanation:

Equate the two opposite Angles

7x - 31 = 5x + 13 Subtract 5x from both sides

7x - 5x - 31 = 13 Combine

2x - 31 = 13 Add 31 to both sides

2x = 13 + 31 Combine the right

2x = 44 Divide by 2

x = 44/2

x = 22
