1/2r−3=3(4−3/2r) plzzzzzzz help!

1 answer:

4 0

Answer:
r= 3

Explanation:
1. Write the division as a fraction
1/2r-3=3(4-3/2r)

2.Distribute the 3 through the paranthesis
1/2r-3=12-9/2r

3.Multiply both sides by 2
r-6=24-9r

4. Swap -6 and -9 together by changing their signs
r+9r= 24+6

5.Add them together
10r=30

6. Divide both sides by 10
r=10

Hope this helped :)

Answer:

1. Yes

2. They could change the 60° angle into a different one.

Step-by-step explanation:

1. Two triangles are the same if they share two side lengths with the same angle between them.

2. Since the triangles are equal if they share two side lengths with the same angle between them, if they changed the angle between 3 and 5, it'd no longer be the same triangle.

Solve for x. <br><br> a²x+(a-8)=(a+8)x

Sergio [31]

$a^2x+(a-8)=(a+8)x\\\\(a+8)x=a^2x+(a-8)\ \ \ \ |subtract\ a^2x\ from\ both\ sides\\\\(a+8)x-a^2x=a-8\\\\(a+8-a^2)x=a-8\ \ \ \ |divide\ both\ sides\ by\ (a+8-a^2)\\\\\huge\boxed{x=\frac{a-8}{a+8-a^2}}\to\huge\boxed{x=\frac{8-x}{a^2-a-8}}$

After the tour, Tyler’s mom bought a pretzel and a bottle of water for each family member. The bottles of water cost $1.50 each.

Delicious77 [7]

Each pretzel is 4.5 $

1.50 • 5 = 7.5
7.5 - 30 = 22.5
22.5 / 5 = 4.5

so in conclusion, those are some expensive a** pretzels.
