3t-7=5t
so add 7 to both sides
3t=5t+7
-5t -5t
-2t=7
/-2 /-2
t=-3.5
6t=
6(-3.5)
-21

First, you would need to solve for t using the equation: 3t - 7 = 5t
Move all the numbers with variable on ones side
-7 = 5t - 3t
Combine like factors
-7 = 2t
Solve for t
-7/2 = t
After solving for t, you plug the answer into the equation you want to solve.
6 (-7/2) = -21
6*-7 <u></u>= -42
-42/2 = -21
The answer is -21

Answer: y=5x/2 - 2.5

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-2.5-2.5)/(0-2)

m=-5/(-2)

m=5/2

y=mx+b

y=5x/2 + b

-2.5=5(0)/2 + b

-2.5=0 + b

b=-2.5

y=5x/2 - 2.5

Why is 6y-12=-3x in standard form? Enter your answer

Because it can't be simplified.
There aren't like terms and there isn't fractions.

How is this written in an expanded version?

Yuri [45]

Powers distribute over multiplications:

$(ab)^c = a^c\cdot b^c$

So, you have

$(3k^5)^2 = 3^2 \cdot (k^5)^2$

Now, $3^2$ is simply 9.

As for $(k^5)^2$ , we have to use the rule

$(a^b)^c = a^{bc}$

to get

$(k^5)^2=k^{5\cdot 2}=k^{10}$

So, the final answer is

$(3k^5)^2 =9k^{10}$

\sqrt{y}+3\sqrt{x}\left(2\sqrt{y}\right)-\sqrt{xy}

Naya [18.7K]

$\bf \sqrt{y}+3\sqrt{x}(2\sqrt{y})-\sqrt{xy}\implies \sqrt{y}+(3\cdot 2)\sqrt{x\cdot y}-\sqrt{xy} \\\\\\ \sqrt{y}+6\sqrt{xy}-\sqrt{xy}\implies \stackrel{\textit{adding like-terms}}{\sqrt{y}+5\sqrt{xy}}$
