y =3

After you set each equation to terms where you can cancel out the x

you are left with:

14y = 42

y = 3

Solve the formula, d=r*t for t
larisa [96]

Hello there!

d=rt

Explanation:

↓↓↓↓↓↓↓↓↓

First you had to do is switch sides of the equation.

rt=d

Then you divide by t from both sides of the equation.

\frac{rt}{t}=\frac{d}{t} ; t\neq 0

Simplify it should be the correct answer.

r=\frac{d}{t} ; t\neq 0

Answer⇒⇒⇒⇒⇒ r=d/t or t≠0

Hope this helps!

Thank you for posting your question at here on Brainly.

Have a great day!

5(-12x+3)+6(10x+7)=9-x+3x+10​
tia_tia [17]

Answer: x = 19

Step-by-step explanation:

5(-12x+3) + 6(10x + 7) = 9 - x + 3x + 10     Distribute on the left side

-60x + 15 + 60x + 42 = 9 + 2x + 10   combine like terms on the left side

   57 = 9 + 2x + 10        Now combine like terms on the right side

57 = 2x + 19        Subtract 19 from both sides

-19           -19

 38 = 2x       Divide both sides by 2

x = 19

Please help me I am so confused it would mean a lot.
Alisiya [41]

Step-by-step explanation:

1. The midpoint formula says the coordinates of the midpoint are the average of the endpoints.

x = (x₁ + x₂) / 2

y = (y₁ + y₂) / 2

I'll do #2 and #3 as examples.

2. x = (-4 + 10) / 2 = 3

y = (6 + -10) / 2 = -2

So the midpoint is (3, -2).

3. x = (-3 + -6.5) / 2 = -4.75

y = (-8 + -4.5) / 2 = -6.25

So the midpoint is (-4.75, -6.25).

Find the missing value of the direct variation (2,5) (5,y)
Karolina [17]

Answer:

The missing value y=12.5 and we have (5,12.5)

Step-by-step explanation:

The formula used for direct variation is:

y\: \alpha \:x\\y=kx

We need to find missing value (2,5)(5,y)

First we will find k, and then y

We have x=2, y=5

Find k:

y=kx\\5=k(2)\\k=\frac{5}{2}\\k=2.5

Now, we cam find missing value in (5,y)

We have x=5, k=2.5 and y=?

y=kx\\y=2.5(5)\\y=12.5

So, the missing value y=12.5 and we have (5,12.5)
