Answer:

16, 32

Step-by-step explanation:

BD is midsegment of the ΔACE ⇒ 16x = 2(3x + 10)

16x - 6x = 20 ⇒ x = 2

BD = 3(2) + 10 = 16 units

AE = 16(2) = 32 units

The sum of Ellie's age and Genya's age is 60. In six years, Genya will be eight times as old as Ellie. How old is Ellie now?

ArbitrLikvidat [17]

Answer:

2 years old

Step-by-step explanation:

Let Ellie's age ⇒⇒⇒ x

And Genya's age ⇒⇒⇒ y

∵ The sum of Ellie's age and Genya's age is 60

∴ x + y = 60 ⇒ (1)

∵ In six years, Genya will be eight times as old as Ellie

∴ (y + 6) = 8 (x+6)

∴ y + 6 = 8x + 48 subtract 6 from both sides

∴ y = 8x + 42 ⇒ (2)

By substituting from 2 at 1 with the value of y

∴ x + (8x + 42) = 60

∴ 9x = 60 - 42 = 18

∴ x = 18/9 = 2

∴ y = 60 - x = 58

So, Ellie's age now = 2 years old

And Genya's age = 58 years old

An algebraic expression of the form a + bx has the value of 15 when x = 2 and the value of 3 when x = 5. Calculate a + b.

Ainat [17]

Answer:

The value of the expression (a +b) = 19

Step-by-step explanation:

The given expression is a + bx.

Case - I when x = 2, (a + bx) = 15

Putting the value of x , we get: a + 2b = 15

or, a = 15 - 2b ...... (1)

CAse II- when x = 5, (a + bx) = 3

Putting the value of x, we get a + 5b = 3

or a = 3 - 5b ....... (2)

Comparing (1) and (2)

15 - 2b = 3 - 5b

or, 5b - 2b = 3 - 15

or, 3b = - 12 ⇒ b = -4

if b = -4, then a = 3 - 5b = 3 + 20 = 23

Hence, a = 23, b= -4

So, the value of (a +b) = 23 - 4 = 19
