Answer:
Step-by-step explanation:
'll just help with proving whether she is correct.
First of all, a fraction divided by a fraction can be made into multiplication since the division of two fractions is kinda difficult
so remember keep, change, flip
keep the first fractions, change the division symbol into multiplication, then flip the fraction i.e. 1/2 becomes 2/1
so 5/2 divided by 1/4 becomes
5/2 * 4/1
which then solved becomes
20/2 which is simplified to 10
Hope this helps :)
Hello!
OK, so first we need to see all of our info.
To rent a bike = $17
Each additional hour = $2 per hour
Let "rent a bike" = r
Let "each additional hour" = h
27 = r + 2h
Now to solve.
27 - 17 = 10
10 ÷ 2 = 5
This shows us that she rented the bike for 5 hours.
Check:
27 =? 17 + 2(5)
Solve:
27 = 17 + 10
27 = 27
Yes, we are correct!
Final equation = 27 = r + 2h
Final answer = Ashely rents the bike for 5 hours.
Hope this helped!
Answer: Completing the square, means
adding ( half the coefficient of the x- term )² to both sides, that is

ur pretty btw
<u>Answer plus step-to-step explanation:</u>
1. Slope formula = Change in y ÷ change in x.
i.e slope(m) =
(Δ means change in)
2. Slope-intercept form is representing equation of a straight line on cartesian plane in the form y = mx + c. <em>Where (m) is the slope of that line and c is the y-intercept.</em>
3. Standard form - is writing numbers in the form of number times ten to power of an exponent. This is also referred to as scientific notation form.
<u>Example:</u>
To write 512 in standard form would be 5.12 × 10²
