One number is seven less than a second number. Three times the first is three more than four times the second .Find the numbers

Answers

Answer:

x = -28 and y = -21

Step-by-step explanation:

Let two numbers be x and y.

One number is seven less than a second number.

x = y-7

x-y = -7 ...(1)

Three times the first is three more than four times the second.

3x = 4y or

3x-4y =0 ...(2)

Multiplying equation (1) by 3. So,

3x-3y = -21 ...(3)

Subtracting equation (2) from (3).

3x-3y-(3x-4y) = -21

-3y+4y = -21

y = -21

Put the value of y in equation (1).

x-(-21)= -7

x+21=-7

x = -21-7

x = -28

So, the value of x and y are -28 and -21 respectively.

Answers

Answer:

C. 41 minutes

Step-by-step explanation:

First, we have to turn 540 seconds into minutes by dividing it by 60

540 ÷ 60 = 9

What is the additive inverse of -10?

Answers

Answer:

The inverse with respect to addition; the opposite. The additive inverse of 12 is −12. The definition of an additive inverse is the number needed to bring a negative number to zero. An example of an additive inverse is the number 30 when added to -30. So the additive inverse of -10 is 10

Step-by-step explanation:

Answer: 10

Step-by-step explanation:

To find the additive inverse of a number, all we should do is change its sign. Thus, the additive inverse of a positive number is a negative number, and the additive inverse of a negative number is a positive one. So the additive inverse of -10, which is negative, is positive 10, or just 10.

What is a true statement about making a purchase ? A-if you purchase an item with credit card, the money to pay for your purchase will be loaned to you B- if you purchase an item with a debit card,you may have to pay interest C-If u purchase an item with a credit card, the money will be deducted from your account D-if you purchase an item with debit card, you will have to pay back the bank for the amount you borrowed.

Answers

Answer:

A- If you purchase an item with a credit card, the money to pay for your purchase will be loaned to you

Step-by-step explanation:

The answer is A because when you use a credit card, any money you spend with it is actually being loaned to you, which you will have to pay back at a later date.

The answer is NOT b because when you are using a debit card, you are using your money that you already own, so you don't have to pay interest on anything.

The answer is NOT c because when you buy stuff with a credit card, the money is being loaned to you, not deducted from your account.

The answer is NOT d because you do not have to pay back a loan with a debit card, that's only with credit cards.
