MA/MN = MB/BP
MA = 46.2 -14
MA=32.2
so
MA/MN = MB/BP
32.2/46.2=x/72.6
46.2x = 72.6 * 32.2
46.2x = 2337.72
x = 2337.72 / 46.2
x = 50.6
Answer:
(-2, 4)
Step-by-step explanation:
In the first equation substitute -2x for y, obtaining: 5x - 9(-2x) = -46
Then 5x + 18x = -46, or 23x = -46, resulting in x = -2
Since y = -2x, y = -2(-2) = 4
The solution is (-2, 4)
Answer:
1)
Ratio is 1:1.
2)
The required number is:
Step-by-step explanation:
1)
Let us consider that Cecilia's has a total of 'x' CDs
and let 'y' represent the number of Jazz CDs.
Now we are given information that:
1/5 of her Jazz CDs represents 1/10 of all her CDs.
i.e.
i.e. the Jazz CDs are half of the total CDs.
Hence, the number of Non-Jazz CDs(z)
=
Hence, the ratio of Jazz to Non-Jazz CDs
Hence, the required Ratio is 1:1.
2)
How would you change to a number times 25?
We will find the number by dividing the quantity by 25 to find the required number.
i.e.
Hence the required number is:
9514 1404 393
Answer:
160
Step-by-step explanation:
The problem statement tells us ...
(# in museum) = 4 × (# waiting)
(# in museum) = 4 × 40 . . . . . . . . . . . . the number waiting is 40
# in museum = 160
