What are the steps to this equation

Harlamova29_29 [7]

Answer:

$x=7$

Step-by-step explanation:

$\frac{2}{5}x+\frac{1}{3}=\frac{1}{3}x+\frac{4}{5}$

Subtract $\frac{1}{3}$ from both sides:

$\frac{2}{5}x+\frac{1}{3}-\frac{1}{3}=\frac{1}{3}x+\frac{4}{5}-\frac{1}{3}$

$\frac{2}{5} x=\frac{1}{3}x+\frac{12}{15}-\frac{5}{15}$

$\frac{2}{5}x=\frac{1}{3}x+\frac{7}{15}$

Subtract $\frac{1}{3} x$ from both sides:

$\frac{2}{5}x-\frac{1}{3}x=\frac{1}{3}x+\frac{7}{15}-\frac{1}{3}x$

$\frac{6}{15}x-\frac{5}{15}x=\frac{7}{15}$

$\frac{1}{15}x=\frac{7}{15}$

Multiply both sides by 15:

$15\times \frac{1}{15}x=\frac{7\times 15}{15}$

$x=\frac{105}{15}$

$x=7$

Point Q is the center of dilation. Lines segment S U is dilated to form line segment S prime U prime. The length of Q S is 3 .2

tia_tia [17]

Answer:

Option C.

Step-by-step explanation:

It is given that the dilation rule is $D_{Q,2.5}$ . It means the center of dilatation is point Q and scale factor is 2.5.

Scale factor is the ratio of distance from center to the image of a point and distance from center to the corresponding point.

$\text{Scale factor}=\dfrac{QU'}{QU}$

It is given that QU=4 and scale factor = 2.5.

$2.5=\dfrac{QU'}{4}$

Multiply both sides by 4.

$2.5\times 4=QU'$

$10=QU'$

We know that

$UU'=QU'-QU$

$UU'=10-4$

$UU'=6$

The distance between U' and U is 6 units.

Therefore, the correct option is C.

Over [174]

Answer:

[2,6]

Step-by-step explanation:

3x+5y=36

5x-4=y

3x+5(5x-4)=36

3x+25x-20=36

28x-20=36

28x=56

x=2

5x-4=y

5*2-4=y

10-4=y
