One Month Yareli made 3 withdrawals for $20 and 1 withdrawal for $80 from her account. How did the withdrawals change the amount in her account?

Answers

Answer:

$140

Step-by-step explanation:

3*20=60

80+60=140

Answer:

The withdrawals would be subtracted away from the account

Step-by-step explanation:

I will use x, as the unknown value for the amount of money left in Yareli's account.

Yareli made a total of 4 withdrawals, all adding up to the sum of $140 withdrawn from the account. So, in the equation, it would kind of look like this:

x - $140.

Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers a which can be expressed as the quotient of two integers

The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient

In this case, the Leading Coefficient is 1 and the Trailing Constant is 3.

The factor(s) are:

a car drove 92 km/h for 4 hours. How far did it travel?

Answers

Answer:

368 km

Explanation:

92 * 4 = 368

Answer:

368 km/h.

Step-by-step explanation:

Hey! Let's solve this problem.

First step: So, you are driving 92km/h for 4 hours, right? Key words are: km, hours, 4 and 92.

So, how would we find this out? All we need to do is multiply 4 x 92, and we get 368! But, make sure when you put your answer put the km/h, as if you don't you could possibly get it wrong.
