PLEASE HELP! I WILL MARK THE BRAINLIEST IF YOU HAVE THE CORRECT ANSWER!! When Sandy and Allen's mother decorates the house for a

holiday by herself, it takes her 5 hours. When both Sandy and Allen help, the three can finish the job in 2.5 hours. When only Allen helps his mother decorate, it takes the two 3.5 hours. How long would it take Sandy to decorate the house by herself?

Sandy would probably take just as long as her mother because it says their mother takes 5 hours if decorating the house alone so if sandy is doing it alone it would also probably take her 5 hours as well. If this is wrong I’m sorry.

Each letter of the alphabet is assigned a numerical value according to its position in the alphabet. Encode the message SEND âHE
SCORPION-xisa [38]

Answer:

<h2>f⁻¹(x) = ∛(x+1)</h2>

Step-by-step explanation:

Given the encoded message defined by the function f(x) = x³-1,  the inverse function that the decoder would need when the message is received can be expressed as thus:

let the inverse of the function be represented as y such that y = x³-1.

Making x the subject of the formula from the equation above;

x³ = y+1

Taking the cube root of both sides:

∛x³ = ∛(y+1)

x = ∛(y+1)

replacing y with x:

y = ∛(x+1)

f⁻¹(x) = ∛(x+1)

The encoded message is the inverse function ∛(x+1)

Seven more than three times a numberis 49 what is the number
Sunny_sXe [5.5K]
Seven more than 3 times a number is equal to 49 can be put into an equation form, which would be 7 + 3x = 49. With this equation we can work it out, first we will subtract 7 from both sides of the equation to cancel out the 7. 49 - 7 = 42. Now we have 3x = 42. To isolate x and give us the answer we will divide by 3 on both sides, since 3 is being multiplied by x. This will give us our answer, which is 14.
