Answer:

x=16

Step-by-step explanation:

4x+30+5x=180

9x+30-30=180-30 (you want to get x to be by itself)

9x/9=150/9

x=16.667

x=16

4x + 30 = 5x

4x = 5x - 30

4x - 5x = - 30

x = 30

Examine the system of equations.

MrMuchimi

answer:

$x = - 2 \\ y = 2 \\ \\ ( - 2, \: 2)$

explanation:

$y = - \frac{1}{2} x + 1 \\ y = 2x + 6 \\ first \: equation \: add \: \frac{1}{2} from \: both \\ sides \\ \\ second \: equation \: subtract \: 2x \: from \\ both \: sides \\ \\ y + \frac{1}{2} x = 1 \\ y - 2x = 6 \\ solve \: the \: first \: equation \\ \\ y + \frac{1}{2} x = 1 \\ subtract \: \frac{x}{2} from \: both \: sides \\ \\ y = - \frac{1}{2} x + 1 \\ substitute \: - \frac{x}{2} + 1 \: for \: y \: in \: the \\ other \: equation \\ \\ - \frac{1}{2} x + 1 - 2x = 6 \\ add \: \frac{1}{2} x \: to \: 2x \\ \\ - \frac{5}{2} x + 1 = 6 \\ subtract \: 1 \: from \: both \: sides \\ \\ - \frac{5}{2} x = 5 \\ divide \: both \: sides \: by \: - \frac{5}{2} \\ \\ x = - 2 \\ substitute \: the \: value \: of \: x \: into \\ an \: equation \\ \\ y = - \frac{1}{2} ( - 2) + 1 \\ distribute \\ \\ y = 1 + 1 \\ add \\ \\ y = 2 \\ \\ ( - 2, \: 2)$

Natali5045456 [20]

Answer: -1/343

Step-by-step explanation:

-7(-7)^-4

First, re-write as positive exponents:

-7(-1/7^4)

Next, simplify:

-1/7^3 (you can simplify using exponent rules)

Simplify 7^3 :

7(7)(7)

49(7)

343.

Insert to original expression:

-1/343.

Divide 33 into two groups so the ratio is 4 to 7 how do you divide it

Vladimir79 [104]

Split 33 into two numbers that when added up are 33.
So 12 to 21, which when divided by 3, are 4 to 7.
