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Yareli made a total of 4 withdrawals, all adding up to the sum of $140 withdrawn from the account.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

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.

−34(x−3)−5=18(x−1)
x =?

Answers

Answer:

x=2.211538462

Step-by-step explanation:

-34x+102-5=18x-18

sub 5 from 102

-34x+97=18x-18

add 18 to both sides

-34x+115=18x

add 34x to both sides

115=52x

divide 52 from both sides

2.211538462=x

Hope this helps! :)

After 8 week Denzel and Halle have the same amount of money in their bank accounts.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Denzel has saved $75 in his bank account and saves an additional $12.50 every week.

And,  Halle has saved $339 in her bank account but spends $20.50 each week.

Now,

Let number of weeks in which Denzel and Halle have the same amount of money in their bank accounts = x

So, We can formulate;

For Denzel;

⇒ $75 + $12.50x

And, For Halle;

⇒ $339 - $20.50x

So, we get;

⇒ $75 + $12.50x = $339 - $20.50x

Solve for x as;

⇒ $20.50 + $12.50 = $339 - $75

⇒ $33x = $264

⇒ x = $264 / $33

⇒ x = 8

Thus, After 8 week Denzel and Halle have the same amount of money in their bank accounts.
