Answer:

Yeah, you're right. ( But please look at the explanation even though it's long. )

Step-by-step explanation:

<u>First. You need to understand each option:</u>

The first option shows that Jordan is taking $45 dollars and then adding $55 dollars to her bank account.

The second option shows that Harshika spent $45 on lunch and then used $20 more dollars.

The third option shows a plane that went up 600 feet then went down 200.

The fourth option shows that Jorge used $60 dollars to buy a sweater and then added $40 dollars.

<u>Then. Understand the question.</u>

The question is asking which option is telling you that the subject is taking money away or going down from an elevation.

<u>Finally. Eliminate, and solve with sense.</u>

Options 1 and 4 show taking away money and then adding money so both of those options are wrong.

Option 3 shows going up and then going down so that option is wrong.

Option 2 shows taking money only so it is the only correct answer.

Why do you have to show work for math
Anton [14]
One of the main reasons you have to show work for math is because your teacher needs to know that you understand the concept. Also, showing work helps your teacher know that you didn't cheat using an online calculator that just gives you an answer.

Evaluate 38+16 * 12÷2-(30 * 2)
Dvinal [7]

Answer

The answer is 8040

Step-by-step explanation:

It might be wrong, but here take it this way with Pemdas.

P= Parenthesis (30*2) and what's in there is multiplication correct? So, 30 times 2 is 60. Then, E is exponents. There's none there. So we skip to multiplication. 16 times 12 is what? 192. Next is division. So 192 divided by 2. That's 96. So, Then it'd be 38+96(60.) 38+96= 134. 134(60) That being said. That would equal  = 8040  using Multiplication, 194 using addition. 74 using subtraction. And 2.2_ using division.

Castel and Chelsea are selling pies for a school fundraiser. Customers can buy cherry pies and lemon meringue pies. Castel sold
tiny-mole [99]

Answer:

the cost each of one cherry pie and one lemon meringue pie is 9 and $12 respectively

Step-by-step explanation:

The computation of the cost of one cherry pie and the lemon meringue pie is shown below:

Let us assume the cherry pie be x

And, the lemon meringue pie be y

So according to the question

x + 5y = $69

5x + 7y = $129

Now multiply by 5 in the equation 1

5x + 25y = $345

5x + 7y = $129

18y = $216

y = $12

And, x would be

x + 5($12) = $69

x = $9

Hence, the cost each of one cherry pie and one lemon meringue pie is 9 and $12 respectively
