Brianna spent 4.00$ on admission to a basketball game she also spent some money at the concession stand in all Brianna spent 16.

Anton [14]

Answer:

4 + x = 16

Step-by-step explanation:

In general, if we have an equation that has just one variable, such as x, then "solving the equation" means finding the set of all values that can be substituted for the one variable to produce a valid equation.

Isolate "x" on one side of the algebraic equation by adding the negative number that appears on the same side of the equation as the "x." For example, in the equation "x - 5 = 12", rewrite the equation as "x = 12 + 5" and solve for "x."

–12(x + 3) - 4(5 - 2x) = 20

12345 [234]

Answer:

x = -19

Step-by-step explanation:

1. make parentheses disappeared using distribution law.

$- 12x - 36 - 20 + 8x = 20$

2. sum up b numbers and x

$- 4x - 56 = 20$

3. separate x and number to two sides of the equation

$- 4x = 76$

4. both side divided by -4

$x = - 19$

Can someone help me with this?

Answer:

Let 'a' be the first term, 'r' be the common ratio and 'n' be the number of terms

Series = 2+6+18.......= 2+2•3¹+ 2•3².......= 728

Now,

$Sum = \frac{a( {r}^{n} - 1) }{(r - 1)} \\$

So,

$\frac{a( {r}^{n} - 1)}{(r - 1)} = 728 \\ \frac{2( {3}^{n} - 1) }{(3 - 1)} = 728 \\ \frac{2( {3}^{n} - 1) }{2} = 728 \\ {3}^{n} - 1 = 728 \\ {3}^{n}=728+1\\ {3}^{n} = 729 \\ {3}^{n} = {3}^{6} \\ \boxed{ n = 6}$

Therefore, number of terms is 6

6 is the right answer.
