Answer:
IDR 480,000
Step-by-step explanation:
Persentase diskon = Harga lama - Harga baru / Harga lama
Harga lama = Harga sebelum diskon = x
Harga Baru = IDR 336000
Persentase diskon = 30%
Karenanya:
30% = x - 336000 / x
30/100 = x - 336000 / x
0.3 = x - 336000 / x
Cross Multiply
0.3 × x = x - 336000
0.3x = x - 336000
x - 0.3x = 336000
0.7x = 336000
x = 336000 / 0.7
x = IDR 480,000

Answer: The length of the rectangle is 16 cm
Step-by-step explanation: The given figure is a rectangle with the size of the perimeter already given.
If the length of the rectangle is twice the width of the rectangle, then
When the width is represented by W, the length would be represented by 2W
Also, the perimeter (P) is given as
P = 2L + 2W
P = 2(L + W)
Given that L = 2W and
W = W
P = 2(2W + W)
48 = 2(3W)
48 = 6W
Divide both sides of the equation by 6
8 = W
Having calculated the width as 8cm, and having in mind that the length of the rectangle is twice it's width
L = 2W
L = 2 × 8
L = 16 cm
Answer:
Tamara should substitute k = 30 into the equation 39 + 2 k = 69
Step-by-step explanation:
or you can do 69-39=30 so k=30
