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

450 push-ups in 18 days
A.35 push-ups/day
B.25 push-ups/day
C.15 push-ups/day
D.45 push-ups/day
Answer:
B.
Step-by-step explanation:
To find the answer you would divide 450 push ups by 18. and that gives you 25 the number of push ups you did in 18 days.

−34(x−3)−5=18(x−1)
x =?
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

A car manufacturer is reducing the number of incidents with the transmission by issuing a voluntary recall. During week 3 of the recall, the manufacturer fixed 391 cars. In week 13, the manufacturer fixed 361 cars. Assume that the reduction in the number of cars each week is linear. Write an equation in function form to show the number of cars seen each week by the mechanic.
f(x) = 3x + 400
f(x) = 3x + 391
f(x) = −3x + 391
f(x) = −3x + 400
please explain ;-;
Answer:
f(x) = -3x + 400.
Step-by-step explanation:
To write the equation in function form to represent the number of cars seen each week by the mechanic, we need to consider the given information.
Let's define:
x: the number of weeks since the start of the recall.
Given that the reduction in the number of cars each week is linear, we can determine the equation by considering the initial number of cars fixed and the reduction rate.
In week 3, the manufacturer fixed 391 cars, which indicates that in the third week (x = 3), the number of cars fixed is 391. This gives us a reference point.
Now, we can find the equation in the form f(x) = mx + b, where m represents the slope (reduction rate) and b represents the initial value (number of cars fixed in the starting week).
To find the slope (m):
We need to determine the change in the number of cars fixed from week 3 (x = 3) to week 13 (x = 13).
The change in x is 13 - 3 = 10.
The change in the number of cars fixed is 361 - 391 = -30.
The slope (m) represents the rate of change, so we calculate it as:
m = (change in the number of cars fixed) / (change in x) = -30 / 10 = -3
Now, we have the slope (m = -3).
To find the initial value (b), we substitute the values of x and f(x) into the equation:
f(3) = 391
Plugging in the values:
-3(3) + b = 391
Simplifying the equation:
-9 + b = 391
Solving for b:
b = 391 + 9 = 400
Now, we have the slope (m = -3) and the initial value (b = 400).
Therefore, the equation representing the number of cars seen each week by the mechanic is:
f(x) = -3x + 400
Denzel has saved $75 in his bank account and saves an additional $12.50 every week. Halle has saved $339 in her bank account but spends $20.50 each week. After how many weeks will Denzel and Halle have the same amount of money in their bank accounts?
Answer: 264 weeks
Step-by-step explanation:
Just subtract $339 and $75 and you will get your answer!
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.

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?
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.
