Answer:

\displaystyle\frac{2}{3}x - 2x = 1 -2 + 9~~~~~~~~~~~~~~~~~~~~~~~~~~~(1)\\\\ \frac{-4}{3}x = 8~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(2)

Step-by-step explanation:

We are given the following information in the question:

We are given a equation:

\displaystyle\frac{2}{3}x - 9 -2x + 2 = 1

We have to write an equivalent equation to the given equation by combining the like terms.

Like terms:

  • Like terms are terms that have the same variables and powers.
  • The coefficients of the like terms do not need to match.
  • Unlike terms are two or more terms that are not like terms, i.e. they do not have the same variables or powers.
  • For example, 2x, 3x, 7x are examples of like terms.

Taking the like terms on one side, we can write the equation as:

\displaystyle\frac{2}{3}x - 2x = 1 -2 + 9~~~~~~~~~~~~~~~~~~~~~~~~~~~(1)\\\\(\frac{2-6}{3})x = 8\\\\\frac{-4}{3}x = 8~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(2)

Equation (1) and (2) are equivalent equation obtained by combining like terms.

Matt and Tikka thought of the same number. Matt added 7 to that number and then doubled the result. He got 26. Tikka did the sam
Reptile [31]

Answer:

19

Step-by-step explanation:

Matt ended up with 26.

We reverse the steps he did to get the original number that both people thought of.

26 / 2 = 13

13 - 7 = 6

6 is the original number.

Tikka did the same operations but in the reverse order so...

6 X 2 = 12

12 + 7 = 19

Can someone please help me with all of these problems. They are a ton of them and they are due tomorrow. PLEASE AND THANK YOU

15. \frac{x}{5} - g = a

Add "g" on both sides

\frac{x}{5}  = a +g

Multiply 5 on both sides to get x by itself

x = 5(a + g)

x = 5a + 5g


18. a = 3n + 1

Subtract 1 on both sides

a - 1 = 3n

Divide 3 on both sides to get n by itself

\frac{a - 1}{3}  = \frac{a}{3} -\frac{1}{3} = n


21. M = T - R

Add "R" on both sides to get "T" by itself

M + R = T


24. 5p + 9c = p

Subtract "5p" on both sides

9c = p - 5p

9c = -4p

Divide 9 on both sides to get "c" by itself

c = \frac{-4p}{9} or c = \frac{-4}{9} p


27. 4y + 3x = 5

Subtract "4y" on both sides

3x = 5 - 4y

Divide 3 on both sides to get "x" by itself

x = \frac{5-4y}{3}

x = \frac{5}{3} -\frac{4y}{3}

The answer should B. 2 because 14/100 is equal to x/14. Simplified it is 100x/100=196/100. 196 divided by 100 equals 1.96 which rounds to 2.
