Answer:
51.5 in , Formula: y=1/2x+48
Step-by-step explanation:
First, create a formula as shown above
Next, plug your number into the formula:
y=1/2(7)+48
Then, simplify your equation by multiplying 1/2 by 7 and getting 3.5, now add 48 and you get 51.5in
Last, check your work by adding 1/2 seven times and you will get the same result
I hope this helps you and if it does please give a thanks (i would eternally appreciate a brainliest trying t level up)

Answer:
<em>Both castles will have the same height at 3.33 minutes</em>
Step-by-step explanation:
This problem will be solved with linear modeling, that is, expressing both people's sand castle's height as a function of time.
Justin built a sandcastle 180 cm tall, and its height is losing at 8 cm/min by the effect of wind. Thus, the height of Justin's sandcastle is:
Where t is the time expressed in minutes.
Taylor's sandcastle is initially 160 cm tall. The wind blows away sand at 8 cm/min but she adds sand at 6 cm/min, thus the real loss of sand is 8 cm/min - 6 cm/min= 2 cm/min. Thus, the height of Taylor's sandcastle is:
To find when both castles have the same height, we set:
Simplifying:
6t=20
Solving:
t=20/6=3.33\ minutes
Both castles will have the same height at 3.33 minutes

Rewriting the whole as an Equivalent Fraction
2.1 Adding a fraction to a whole
Rewrite the whole as a fraction using 3 as the denominator :
8 8 • 3
8 = — = —————
1 3
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:
8 • 3 + 1 25
