Find the ratio of x to y if 7/x = 5/y. Help me!!!!

MakcuM [25]

7/x = 5/y
Can be changed to:
5x = 7y
So, x = (7/5)y and
y = (5/7)x

Y+2 = -3(x – 4)<br> Complete the missing value in the solution to the equation. <br><br> (?, -2)

ss7ja [257]

Answer:

The missing value in the solution to

the equation will be:

$x=4$

Step-by-step explanation:

Given the equation

$y+2\:=-3\left(x\:-\:4\right)$

As the value of y = -2 is given.

so substituting the value y = -2 in the equation to find the missing value

$\left(-2\right)+2\:=-3\left(x\:-\:4\right)$

switch the sides

$-3\left(x-4\right)=\left(-2\right)+2$

$\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a$

$-3\left(x-4\right)=-2+2$

$-3\left(x-4\right)=0$

$\mathrm{Divide\:both\:sides\:by\:}-3$

$\frac{-3\left(x-4\right)}{-3}=\frac{0}{-3}$

$x-4=0$

$x=4$

Therefore, the missing value in the solution to

the equation will be:

$x=4$

In the diagram, VZ/YZ=WZ/XZ. To prove that △VWZ ~ △YXZ by the SAS similarity theorem, which other sides or angles should be used

Vitek1552 [10]

Answer:

The angles $\angle VZW\cong \angle YZX$ are used to prove the similarity of triangles VWZ and YXZ.

Step-by-step explanation:

Given information: $\frac{VZ}{YZ}=\frac{WZ}{XZ}$

Two triangles are called congruent if their corresponding sides are in same proportion or the corresponding angles are same.

If two corresponding sides of triangle have same proportion and their inclined angle is same, then by SAS rule of similarity both triangles are similar.

From the given figure it is noticed that the ∠VZW and ∠YZX are vertically opposite angles. The vertically opposite angles are always equal.

$\angle VZW=\angle YZX$ (Vertically opposite angles)

$\frac{VZ}{YZ}=\frac{WZ}{XZ}$ (Given)

By SAS rule of similarity

$VWZ\sim YXZ$

Therefore the angles $\angle VZW\cong \angle YZX$ are used to prove the similarity of triangles VWZ and YXZ.
