Answer:

$\frac{2x^2-3x}{7}$

Step-by-step explanation:

$\frac{2x-3}{x}$ ÷ $\frac{7}{x^2}$

=> $\frac{2x-3}{x}$ × $\frac{x^2}{7}$

=> $\frac{2x-3}{7}$ × $\frac{x^2}{x}$

=> $\frac{x(2x-3)}{7}$

=> $\frac{2x^2-3x}{7}$

The measures of two supplementary angles are (3x + 9)° and (2x + 2)°. What is the measure of the smaller angle? A. 16.6° B. 69.6

s344n2d4d5 [400]

Answer:

Step-by-step explanation:

Supplementary angles sum to 180°, hence

3x + 9 + 2x + 2 = 180, that is

5x + 11 = 180 ( subtract 11 from both sides )

5x = 169 ( divide both sides by 5 )

x = 33.8

Hence the smaller angle has a measure of

2x + 2 = (2 × 33.8) + 2 = 67.6 + 2 = 69.6° → B

The variables y and x^2 are directly

choli [55]

Answer:

y = $\frac{20}{21}$ x²

Step-by-step explanation:

Given that y and x² are directly proportional then the equation relating them is

y = kx² ← k is the constant of proportion

When x = 2

y = k × 2² = 4k

When x = 5

y = k × 5² = 25k

Then

25k - 4k = 20 ( difference between values is 20 )

21k = 20 ( divide both sides by 21 )

k = $\frac{20}{21}$

y = $\frac{20}{21}$ x² ← equation of proportion
