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.
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Yareli made a total of 4 withdrawals, all adding up to the sum of $140 withdrawn from the account.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.

Rewriting the whole as an Equivalent Fraction
2.1 Subtracting a fraction from a whole
Rewrite the whole as a fraction using 4 as the denominator :

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
2.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

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:
