Let the number be y

The statement can be interpreted as

85% of y = 646

$\begin{gathered} \text{ }\frac{85}{100}\text{ x y = 646} \\ 85y\text{ = 64600} \\ y=\frac{64600}{85} \\ y=760 \\ \text{ The number is 760} \end{gathered}$

The triangles below are similar. What is the value of x ?

Mandarinka [93]

Answer:

Step-by-step explanation:

Since triangle ADE and triangle ABC are similar, that means their sides are proportional, thus we get the equation

$\frac{AD}{AB} =\frac{DE}{BC}$

$\frac{2}{6} = \frac{x}{12}$

$6x = 24\\x=4$

Thus the value of x is 4

Answer:

See attached graph

Step-by-step explanation:

The equation is y-3=(x + 6)

Write the equation in a slope intercept form, then graph the equation on a graph tool to see the points that line on the line.

Alternatively , using the coordinates in the answer choices given, input them in the equation of the graph and select the answer choice that has all its coordinates true to the equation.

y-3 = x+6 -----can be written as : y= x+9

Graph y= x+9 to see the graph and the points that are on the line as attached.
