X Is a number so ( x +12) a
Answer:
Step-by-step explanation:
3.5x - 10 > -3
3.5x > 7
x > 2
8x - 9 < 39
8x < 48
x < 6
x > 2 and x < 6
Let d = # of dimes
Let q = # of quarters
equation #1: number of coins
d + q = 1234
equation #2: value of coins
0.10d + 0.25q = 290.05
Solve #1 for d:
d=1234-q
Sub #1 into #2 and solve for q:
0.10d + 0.25q = 290.05
0.10(1234-q) + 0.25q = 290.05
123.4 - 0.10q + 0.25q = 290.05
0.15q = 166.65
q = 1111
Now go back to d=1234-q and sub in 1111 for q to find d:
d = 1234 - 1111
d = 123
1111 quarters and 123 dimes.

Answer:

Step-by-step explanation:
Cosine of an angle:
The cosine of an angle, in a right triangle, is the length of the side adjacent to this angle divided by the hypotenuse.
Length of the largest side:
The length of the largest side is 41, that is, the hypotenuse is 41. The hypotenuse is XW.
WY = 9.
This means that the length of the adjacent side to angle W is 9.
What ratio represents the cosine of ∠W?
Adjacent side has length 9, hypotenuse has length 41. So
