Answer:

x = 12

Step-by-step explanation:

Equation:    0.52(x) + 0.72(4) = 0.57(x + 4)

0.52(x) + 0.72(4) = 0.57(x + 4)             \longmapsto         Multiply

0.52x + 2.88 = 0.57x + 2.28               \longmapsto         Subtract 0.52x from both sides

2.88 = 0.05x + 2.28                            \longmapsto         Subtract 2.28 from both sides

0.6 = 0.05x                                          \longmapsto        Divide all sides by 0.05

 

x = 12

Laura has 24 stamps from each of 6 different countries. She can fit 4 stamps on each display sheets of an album. How many displa
Ket [755]
B. 36
To find the number of sheets that Laura is going to fill with her stamps, we first have to find the total number of stamps.
If she has 24 stamps EACH from 6 countries, to get the total, we will multiply
24 x 6 = 144 total number of stamps.

to see how many sheets she will fill we will DIVIDE the total number of stamps by 4 because that is the number she can fit onto One display sheet.
144 ÷ 4 = 36
36 sheets will be used to put four stamps each from a total of 144 stamps.

28xw+7wy-4kx-ky<br><br> Factor the polynomial completely<br><br> Thank you!
Genrish500 [490]

Answer:

(7w - k)(4x + y)

Step-by-step explanation:

Factor by grouping is best for this expression. To factor by grouping, group pairs of terms with parenthesis. Then find the GCF in each pair. If the parenthesis match after, the factoring is complete.

28xw + 7wy - 4kx - ky

(28xw + 7wy) + (- 4kx - ky)

7w(4x + y) - k (4x + y)

The factors are (7w - k)(4x + y).
