Answer:
x- 5
y- 6
Step-by-step explanation:
A proportional relationship is a relationship for which a proportional constant y/x exists and for which it passes through (0,0) or the origin.
The proportional constant is 6.
18/3=6
42/7=7
54/9=6
Thus the filled in blanks should be x 1, 3, 5, 7, 9 and y 6, 18, 30, 42, 54.
To
get the milliliters of alcohol used, we must multiply 690 by 0.03. If we do
this, we will get 20.70, which means that 20.70 milliliters of alcohol were
used. On the other hand, we can get the milliliters of water used through two
ways: the first one is by simply subtracting 20.70 from 690, which will give us
the answer 669.30. Another would be by multiplying 690 by 0.97, which will also
yield the answer 669.30. The number of milliliters of water used was 669.30.

Answer:
x = 
Step-by-step explanation:
AC² = AB² + BC²
BC² = 3² + x² = 9 + x²
AB² = 7² + x² = 49 + x²
But AC² = (7 + 3)² = 100
∴ 100 = 49 + x² + 9 + x²
2x² + 58 = 100
x² = 50 - 29 = 21
x =
Answer:
135°
Step-by-step explanation:
Since there are a pair of parallel lines, then
∠3 = ∠1 = 135° ( corresponding angles are congruent )
