Which value from the set {2, 3, 6, 7} makes 3x + 5 = 11 true?

A. 2

B. 3

C. 7

D. 6

Answers

Answer:

To solve this equation, you need to isolate the variable (in this case, x) on one side of the equation. To do this, you can start by subtracting 5 from both sides of the equation:

3x + 5 - 5 = 11 - 5

This simplifies to:

3x = 6

To isolate the x term, you can divide both sides of the equation by 3:

(3x)/3 = 6/3

This simplifies to:

x = 2

Therefore, the correct answer is option A: 2.

Answer:

The correct answer is A

Step-by-step explanation:

3x = 11-5

3x = 6

x = 2

Make a the subject of the formula:
a/5=12b

Answers

Answer: a = 60b

Step-by-step explanation: simplifying both sides of the equation, then isolating the variable. So 60 divided by 5 = 12

60a/5 = 12b

x:4 and 45:20
o 8
o 9
o 10

Answers

Answer:

Step-by-step explanation:

What I am seeing is that these two are equal ratios. If 20 divided by a number=4 we do 20/4=5 so we have to divide 45 by 5 to find out what x is equal to. If this doesn’t make sense read it a couple of times and watch videos on how to find missing equal ratios. Hope this helps!

Leila is selling raffle tickets. The table shows the cost (in dollars) of buying different numbers of tickets.
Using x for the number of tickets and y for the cost, do the following.

Answers

You can do 2x, so what ever number in in the x column you sub into the x so the first x is 1 so it would be 2(1) which is equal to 2, the y column. Next one would be 2(2) which is equal to 5 the next y column. So 2x=y. I’m not sure if I answered what you were asking

The answer would be 2x.

If you want a quick explanation..
y2-y1/x2-x1

y2=4 y1=2 x2=2 x1=1

Bottled water: A liter of tap water costs around $0.05 at home. While a liter of bottled water costs around $2 at the store. Calculate the percent of this markup. Round to the nearest percent.

Answers

Answer:

4000%

Step-by-step explanation:

To calculate the percent markup, we need to first find the difference between the cost and the selling price: $2.00 - $0.05 = $1.95

Then, we can divide that difference by the cost and multiply by 100% to express the result as a percentage:

($1.95 / $0.05) * 100% = 3900%

So the percent markup on the liter of bottled water is around 3900%. Rounded to the nearest percent, this would be 4000%.

4000% here is the answer

Im going to call it a hanger because thats what my teacher called it.

Explanation:
So both sides of the hangar are equal.
Your goal is to find what each shape is worth.
And the number at the top shows what both sides combined equals.
Since both sides have to be equal you would divide 40 by 2 to represent both sides of the hangar.
So with that both sides equal 20, start on the right because its all one shape.
All four of those triangles combine to equal 20 so you would divide 20 by 4 to get how much each individual shape is worth which would be 5 each purple triangle equals 5.
Knowing this, on the left side you would subtract 5 to represent the triangle which would be 20-5 which equals 15.
You have 5 orange hearts/circles ( i cant see what they are so im going to say circles) so again you would divide 15 by 5 to get each individual shapes value. Leaving you with 3.

Answer:
Purple triangle: 5
Orange circle: 3

Hope this helps and sorry if it was messy!

Both sides will have the same answer. Which is 20, just half the 40.

Right side:
20 divided by 4, will give you 5.
This is the worth of the pink one.

Left side:
20 - 5, is 15.
15 divided by 5 (because of the number of orange in that side) = 3

Answer:
Pink = 5
Orange = 3

PLEASE HELP ME I’M CONFUSED

Answers

Answer:

Step-by-step explanation:

I did this quickly so you'd get an answer so appologies for any errors.

1. The change from 7 gallons to 5 is -2/3 or -.667 a minute because it decreases 2 gallons in 3 minutes.

2. 5 gal = (2/3 gal/min)(x minutes)

x = 5(3/2) = 15/2 = 7.5 minutes to drain the remaining 5 gallons.

3. There was 10 gallons when the tank is full

That is 3 gallons more than the 7 gals there when Jada arrived.

(2/3)(x) = 3

x = 3(3/2) = 9/2 = 4 1/2 minutes

4 1/2 minutes before Jada arrived

Omg same Chromebook twinsies LOL

Can someone please help me. Due tomorrow.

Answers

Answer:

Rate of change = 142/5 = 28.4

Initial population = 5,428 - 142(5)

= 5,428 - 710

= 4,718

Rate of change/Initial population

= 28.4/4,718 = 71/11,795 = about .602%
