Step-by-step explanation:

Step 1: Define

3t + 7 = 2 + 5t

Step 2: Solve for t

[Subtraction Property of Equality] Isolate t terms: 7 = 2 + 2t
[Subtraction Property of Equality] Isolate t term: 5 = 2t
[Division Property of Equality] Isolate t: 5/2 = t
Rewrite: t = 5/2

Answer:

Explanation:

3t + 7 = 2 + 5t

Simplify both sides of the equation

3t + 7 = 5t + 2

Subtract 5t from both sides

3t + 7 − 5t = 5t + 2 − 5t

−2t + 7 = 2

Subtract 7 from both sides

−2t + 7 − 7 = 2 − 7

−2t = −5

Divide both sides by -2

−2t / -2 = −5 / -2

Simplify

t = ⁵⁄₂

Turn the fraction into a decimal

t = 2.5

t = ⁵⁄₂ or 2.5

Find the equation of a line that goes through the points (-3,5) and (5,-11)

Rasek [7]

$(\stackrel{x_1}{-3}~,~\stackrel{y_1}{5})\qquad (\stackrel{x_2}{5}~,~\stackrel{y_2}{-11}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-11}-\stackrel{y1}{5}}}{\underset{run} {\underset{x_2}{5}-\underset{x_1}{(-3)}}}\implies \cfrac{-16}{5+3}\implies \cfrac{-16}{8}\implies -2$

$\begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{5}=\stackrel{m}{-2}(x-\stackrel{x_1}{(-3)}) \\\\\\ y-5-2(x+3)\implies y-5=-2x-6\implies y=-2x-1$

(6 to the power of 3 times 3 to the power of 3) to the power of 2

frosja888 [35]

Answer:

True

Step-by-step explanation:

(6³ * 3³)² = 18⁶

Multiply inside the parenthesis.

(18³)² = 18⁶

When you put powers to powers, they multiply, eg:

(x³)⁴ = x³°⁴ = x¹²

18⁶ = 18⁶

True.

The length of each side of a cube is x cm. If x is an interference,why can’t the volume of the cube equal 15 cm

slamgirl [31]

we don't know what the value of "X" is, so therefore, we cannot conclude that it is 15 cm.
