Sara says, "If you subtract 12 from my number and multiply the difference by - 3, the result is
- 45." What is Sara's number?

Answers

Answer 1

Answer:

3

Step-by-step explanation:

Answer 2

Answer:

[tex]27[/tex]

Step-by-step explanation:

Let Sara's number be [tex]x[/tex]. Now, we can build an equation.

We have that [tex]-3(x-12)=-45[/tex]. Aha! Now we have a path to the solution!

We can divide both sides of the equation by [tex]-3[/tex] to get [tex]x-12=15[/tex].

Lastly, we add [tex]12[/tex] to both sides to get [tex]x=27[/tex].

So, Sara's number is [tex]\boxed{27}[/tex].

Illinois' population is now 12.5 million and decreasing by 0.1 million each year. On the other hand, Arizona's population is 6.9 million and increasing by 0.6 million each year. In how many years will the two states have the same population?

Answers

Answer:

8 years

Step by step guide:

100,000 x 8 = 800,000

600,000 x 8 = 4,800,000

6,900,000 + 4,800,000 = 11,700,000

12,500,000 - 800,000 = 11,700,000

what is the value of the function when x = 0? ​

Answers

Answer:

f(0) = -2.

Step-by-step explanation:

This question pertains to the y-intercept. By definition, the y-intercept is the point on the graph where it crosses the y-axis, and has coordinates, (0, b). It is also the value of y when x = 0.  Looking at the graph, the point where the line crosses the y-axis is (0, -2). The y-coordinate is the y-intercept, b.

Therefore, the value of the function when x = 0 is: f(0) = -2.

ALGEBRA Ishiro Murakami has $15.60 deducted weekly for
family medical insurance. His employer pays 85% of the cost.
What is the annual premium?

Answers

Murakami's Annual premium which is the total value of medical insurance in a year is $5408

Percentage paid by employer = 85%Percentage paid by worker = 15%Number of weeks in a year = 52

Annual deduction from worker's salary = 52 × 15.60 = $811.2

15% of annual premium = 811.2

Let annual premium = p

Therefore,

15% × p = 811.2

0.15p = 811.2

Divide both sides by p

p = 811.20 / 0.15

p = $5408

Therefore, his annual premium is $5408

If 8 pizzas cost $72,how much will 15 pizzas cost

Answers

Answer: $135

Explanation: To find how much 15 pizzas will cost, first we have to find out how much just one pizza will cost. To do this, you have to divide both the number of pizzas (8) and also the price for those 8 pizzas ($72) by the number of pizzas (8 again). When you do this you get the price of one pizza. Then you multiply the price of one pizza by the amount of pizzas you actually need to find the value for (15). This is a lot to explain but don't lose hope! Let me show you step by step and it'll make more sense.

Step 1) Divide both the amount of pizzas and the cost of that many pizzas

8 ÷ 8 = 1

72 ÷ 8 = 9

This means that one pizza costs 9 dollars.

Step 2) Multiply the cost of one pizza by 15 (the amt of pizzas you need to find the cost for)

15 × 9 = 135

135 is the cost for 15 pizzas. I hope this helps you!

So sense the total of 8 pizzas equal 72 we need to know how much the cost is for 1 pizza.

In that case we will do 72 divided by 8. And that equals 9.

Now that we know the cost for 1 pizza each is (9),

we do 9x15 to get the total cost of 15 pizzas and that is $135.

A down payment of $195 is made on a television that costs $1300. What percent of the
cost is the down payment?

Answers

6.66666667% I hope that is helpful to you

Answer:

15%

Step-by-step explanation:

Add 195 to 1300, which gives you, 1495.

Use the formula for percent change:  Difference = % * original price.

So what is the difference between 1495 and 1300? It’s 195.

Now we have 195 as the difference.

Do we know the original price of the TV? Yes we do. What is it? Its 1300 because the question states the TV costs $1300.

Now we have the equation 195 = % * 1300

We don’t know the percentage, right? So now we have to solve for %. To do that, you have to do 195 divided by 1300, which gives you 0.15. Lastly, you have to turn 0.15 into a percentage, to do that, multiply 0.15 by 100, and it should give you 15%.

Therefore, 15% is the down payment. Hope this helps!

You are really excited to have found a Puch Maxi Moped from the mid Eighties, and the spring weather is making you want to get out and ride it around. It doesn't run on straight gasoline, you have to mix the oil and gas together in a specific ratio of 2.4 fl. oz. of oil for every gallon of gasoline.
You have 3.75 gallon of gas. How much oil should you add?

Answers

Answer:

Step-by-step explanation:

You should add 9 fl. oz. of oil to your 3.75 gallons of gas.

Puch Maxi Moped from the mid-Eighties now since this moped doesn't run on straight gasoline, you need to create a special fuel mixture. This involves combining oil and gas in a specific ratio. The magic ratio here is 2.4 fl. oz. (fluid ounces) of oil for every gallon of gasoline.

You mentioned you've got 3.75 gallons of gas. To figure out how much oil you need, we can use some math. First, let's find out how much oil is required for one gallon of gas:

2.4 fl. oz. of oil/gallon x 1 gallon = 2.4 fl. oz. of oil.

So, for 3.75 gallons of gas, you'll need:

2.4 fl. oz. of oil/gallon x 3.75 gallons = 9 fl. oz. of oil.

You should add 9 fluid ounces of oil to your 3.75 gallons of gas to create the proper fuel mixture for your Puch Maxi Moped.
