Answer:

20 and 50

Step-by-step explanation:

x + y = 70

y = 2x + 10

Use the substitution method:

y = 70 - x

y = 2x + 10

70 - x = 2x + 10

3x = 60

x = 20

x + y = 70

20 + y = 70

y = 50

<u>x = 20</u>

<u>y = 50</u>

<u />

Please help me with this question
Vlad1618 [11]

Answer:

Step-by-step explanation:

a1 = 3;

a2 = 2(a1 - 2 ) = 2(3-2) = 2

a2 = 2

a3 = 2(a2-2) = 2(2-2) = 0

a3=0

a4 = 2(a3-2) = 2(0-2) = -4

a4 = -4

a5 = 2(a4 - 2) = 2(-4-2) = -12

a5 = -12
