What is the value of _a_ in the equation below?

2a + 3 = 4a + 5

Answers

Step-by-step explanation:

hope it is helpful to you

Step-by-step

Simplifying 2a + 3 = 4a + 5

Reorder the terms: 3 + 2a = 4a + 5

Reorder the terms: 3 + 2a = 5 + 4a

Solving 3 + 2a = 5 + 4a

Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right.

Add '-4a' to each side of the equation. 3 + 2a + -4a = 5 + 4a + -4a

Combine like terms: 2a + -4a = -2a 3 + -2a = 5 + 4a + -4a Combine like terms: 4a + -4a = 0 3 + -2a = 5 + 0 3 + -2a = 5 Add '-3' to each side of the equation. 3 + -3 + -2a = 5 + -3 Combine like terms: 3 + -3 = 0 0 + -2a = 5 + -3 -2a = 5 + -3 Combine like terms: 5 + -3 = 2 -2a = 2 Divide each side by '-2'. a = -1 Simplifying a = -1

Write a unit rate for the situation.
$12.50 for 5 ounces

Also if you can, with your answer can you tell me how to find unit rate?

Answers

Answer:

$2.50 for 1 ounce

Step-by-step explanation:

I hope this helps

Answer:

The correct answer is $2.50.

Step-by-step explanation:

The unit rate is what we use to determine the price of a single unit, when something is sold in a group, as in this case 5 ounces.

We have been told that $ 12.50 is the price for 5 ounces, but what we want to know is how much 1 ounce costs.

To determine this, what we must do is divide the total price by the quantity of ounces, in order to determine the unit price:

12.50 / 5 = 2.50

In this way we can verify that the unit price of 5 ounces

Happy Paws charges $16.00 plus $2.50 per hour to keep a dog during the day. Woof Watchers charges $11.00 plus $3.75 per hour. Complete the equation and solve it to find for how many hours the total cost of the services is equal. Use the variable h to represent the number of hours.

Answers

Answer:

Equation: 2.5x + 16 = 3.75x + 11

Hours: 4

Step-by-step explanation:

Hi,

The equation would be...

2.5x + 16 = 3.75x + 11

(To find the solution, you have to set the equations equal to each other)

2.5x is the cost per hour at Happy Paws and the 16 is the charge. For Woof Watchers, the 3.75x is the cost per hour and the 11 is the charge.

Now solve...

2.5x + 16 = 3.75x + 11

Subtract 16 on both sides...

2.5x = 3.75x - 5

Subtract 3.75x on both sides...

-1.25x = -5

Divide by -1.25 on both sides...

x = 4

So at 4 hours, both services will have an equal total of cost.

The following cards are used in a game. If each of the cards is turned over and shuffled, then how much of a greater chance is there in drawing a spade over drawing a 7?

Answers

Answer:

1/6 of a chance aka 16.666?%

Step-by-step explanation:

The probability of drawing a card with number 7 is 0.166.

What is the probability?

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.

From the given set of cards,

Total number of cards =6

Number of spades = 3

Number of card with number 7 on it = 1

Probability of drawing a 7 = 1/6

= 0.166

Therefore, the probability of drawing a card with number 7 is 0.166.

4/9 kilogram of baking soda costs $2. How much does 1 kilogram of baking soda cost?

please drop an explanation, and equation thanks!

Answers

Ok so we want to cross multiply.
To do this you know 4/9=2$ so now you want to know 1=x$
When you do this you get $5

Answer:

1 kg of baking soda costs $4.50.

Step-by-step explanation:

Write and solve an equation of ratios, as follows:

 4/9 kg            $2

------------- = --------------

    1 kg               x

Multiplying both numerators by 9, we get:

  4 kg          $18

------------ = ---------

   1 kg             x

Cross-multiplying, we get 4x kg = $18-kg.  Solving for x, we get:

        $18-kg

x = -------------- = $4.50

         4kg

1 kg of baking soda costs $4.50.
