Hidhri is five years more than kawthar. if sum of their age is 36 years find their age

Hidhri is 20 years old

Kawthar is 15 years old

Step-by-step explanation:

Hidhri is x years old

Kawthar is y years old

x = 5 + y  (Hidhri is five years more than Kawthar)

x + y = 36  (sum of their age is 36 years)

Substitute:

(5 + y) + y = 36

5 + y + y = 36

5 + 2y = 36

2y = 36 - 5

2y = 31

y = 31 ÷ 2

y = 15.5

Kawthar is 15 years old.

Since Hidhri is five years more,

15 + 5 = 20

Hidhri is 20 years old.

i think the answer is fried chicken ; >

step-by-step explanation:

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
