Answer:

J+12=25 J=25-12

J=13

K-16=4 K=4+16

K=20

C+8=12 C=12-8

C=4

R / 10 =4 R =4 x 10

R=40

64=16 x U. U= 64 / 16

U=4

3 x v = 12 V = 12 / 3

V= 4

Step-by-step explanation:

J=13

K=20

C=4

R=40

U=4

V= 4

You would do (2x+60)+6x=180... when you simplify you get 15.

(0,0), (1,5), (2,20), (3,45), (4,80) what's the rule?

yanalaym [24]

Hmm, seems to multiply by 5
wait, no

first is multiply by 5
2nd is multiply by 10
3rd is multiply by 15
4th is multiply by 20
seems to be

$f(x)=x(5x)$ or $f(x)=5x^2$
the rule is square the input then multiply by 5

\large -\frac{2}{3}x+3=\frac{2}{3}x+\frac{1}{3}

Answer:

$\boxed {x = 2}$

Step-by-step explanation:

Solve for the value of $x$ :

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

-Take $\frac{2}{3}x$ and subtract it from $-\frac{2}{3}x$ :

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

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

-Subtract both sides and convert $3$ to a fraction:

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

$-\frac{4}{3}x = \frac{1}{3} - \frac{9}{3}$

Since both $\frac{1}{3}$ and $\frac{9}{3}$ have the same denominator, then you would subtract the numerator:

$-\frac{4}{3}x = \frac{1 - 9}{3}$

$-\frac{4}{3}x = \frac{8}{3}$

-Multiply both sides by $-\frac{3}{4}$ , which is the reciprocal of $-\frac{4}{3}$ :

$x = \frac{8}{3} (-\frac{3}{4})$

$x = \frac{-8(-3)}{3 \times 4}$

$x = \frac{24}{12}$

-Divide $24$ by $12$ :

$x = \frac{24}{12}$

$\boxed {x = 2}$

So, therefore, the value of $x$ is $2$ .
