When letters are used in math, it is usually concerning algebra. If you can give me an equation, I would be happy to explain how to solve it.

Answer:

Step-by-step explanation:

Letters are variables and those variable can store a number

Ex: x=5  y=2

evaluate : 3x+2y

we know that x is 5, so we know that 3x would be 15

we know that y is 2, so we know that 2x would be 4

then it says to add 3x and 2y, we would add 15 and 4 to get 19

(This is a very simple example, when you get older, the expression would be much more confusing.

tia_tia [17]
I believe the wording of the question is: If one tray can hold 12 loaves of bread and the rack can hold 10 trays, can a hundred and twenty-five loaves fit on one rack? 
Then the answer would be, no. 
12 x 10 = 120

Alchen [17]

Step-by-step explanation:

sqrt(5x)×(sqrt(8x²) - 2×sqrt(x)) =

sqrt(5x × 8x²) - 2×sqrt(5x × x) =

sqrt(40x) × x - 2x × sqrt(5) =

2x×sqrt(10x) - 2x×sqrt(5)

therefore, the last option is correct.

"The output is one-fourth of the input."
Alenkasestr [34]

Step-by-step explanation:

Using functions, the input is x, the output is y.

<u>Break down the problem:</u>

The output (y) is (equals) one-fourth (1/4) of the input (x)

y equals 1/4 of x

y =  \frac{1}{4} x

ASAP PLS
Wittaler [7]

Assuming Earth's gravity, the formula for the flight of the particle is: 


s(t) = -16t^2 + vt + s = -16t^2 + 144t + 160. 


This has a maximum when t = -b/(2a) = -144/[2(-16)] = -144/(-32) = 9/2. 


Therefore, the maximum height is s(9/2) = -16(9/2)^2 + 144(9/2) + 160 = 484 feet.
