If we know just two sides of a triangle, we can find the measure of theangles. Step 1: Choose which trig ratio to use. We need to determine how the two sides we know the length of are related to angle A. The 4 in. side is adjacent to A and the 7 in.

Write as an expression: a number that is equal to twice as much as x

lesantik [10]

Let's call the number we're looking for $y$ . We know that $y$ is twice as much as $x$ .

Twice as much as a number simply means the double of that number, and in turn the double of a number means to muliply that number by 2.

So, in order to obtain $y$ , you have to multply $x$ by 2. In formula, you have

$y = 2\cdot x$ or simply $y = 2x$

Answer: $\bold{x=\dfrac{11}{21}}$

Step-by-step explanation:

$\dfrac{2}{3}-\dfrac{4x+7}{2}=-9x+\dfrac{5}{6}\\\\(6)\dfrac{2}{3}-(6)\dfrac{4x+7}{2}=-9x(6)+(6)\dfrac{5}{6}\qquad \text{(multiplied by LCD) }\\\\4 - 12x-21=-54x+5\qquad \text{(simplified)}\\\\-12x - 17 = -54x + 5\qquad \text{(added like terms)}\\\\42x-17=5\qquad \text{(added 54x to both sides)}\\\\42x = 22\qquad \text{(added 17 to both sides)}\\\\x=\dfrac{22}{42}\qquad \text{(divided both sides by 42)}\\\\x=\dfrac{11}{21}\qquad \text{(reduced the fraction)}$
