A)
Let x = sister's age
Kim's age is twice that of her sister
so Kim's age = 2x
Kim’s age + Sister’s age = 36
equation:
x + 2x = 36

b) solve the equation x + 2x = 36

x + 2x = 36
3x = 36
x = 36 / 3
x = 12
Kim's age = 2x = 2(12) = 24

answer
Sister's age is 12 and Kim's age is 24.

velikii [3]

Total circle = 360°
1/2 of circle = 1/2 x 360 = 180°
1/4 of the circle = 1/4 x 360 = 90°

Similarly,
1/8 of the circle = 1/8 x 360 = 45°

sergij07 [2.7K]

Solution:

The cost for Dana and Courtney's lunch is $24

They want to leave a 15% tip

To find: total cost of their lunch, including the tip

Find the tip amount

Tip amount = 15 % of 24

$Tip\ amount = \frac{15}{100} \times 24\\\\Tip\ amount = 0.15 \times 24\\\\Tip\ amount = 3.6$

what is the total cost of their lunch, including the tip?

Total cost = cost of lunch + tip amount

Total cost = 24 + 3.6

Total cost = 27.6

Thus total cost of their lunch, including the tip is $ 27.6
