Jack, walker, and trust have $100 altogether. Jack has $20 more than Walker. Trust has $14 more than walker. How much money does

nekit [7.7K]

Answer: Jack has $42

Step-by-step explanation:

Let be "j" the amount of money in dollars that Jack has, "w" the amount of money in dollars that Walker has and "t" the amount of money in dollars that Trust has.

You know that they have $100 altogether, then you can write the following equation:

$j+w+t=100$ [Equation 1]

Jack has $20 more than Walker, then:

$j=w+20$ [Equation 2]

And Trust has $14 more than walker, then you can write this equation:

$t=w+14$ [Equation 3]

Substitute the Equation 2 and the Equation 2 into the first one:

$j+w+t=100\\\\(w+20)+w+(w+14)=100$

Now, solve fo "w":

$w+20+w+w+14=100\\\\3w+34=100\\\\3w=100-34\\\\w=\frac{66}{3}\\\\w=22$

Finally, substiute the value of "w" into the Equation 2 and evaluate:

$j=w+20\\\\j=22+20\\\\j=42$

4(4m-3)-m(m-5)=-52 need all the steps

nadezda [96]

$\huge\mathcal {♨Answer♥}$

$\large\texttt{Simplifying: }$

4(4m -3) + -1m(m + -5) = -52

$\large\texttt{Reorder the terms: }$

4(-3 + 4m) + -1(m + -5) = -52

(-3 * 4 + 4m * 4) + -1(m + -5) = -52

(-12 + 16m) + -1(m + -5) = -52

$\large\texttt{Reorder the terms: }$

-12 + 16m + -1(-5 + m) = -52

-12 + 16m + (-5 * -1 + m * -1) = -52

-12 + 16m + (5 + -1m) = -52

$\large\texttt{Reorder the terms: }$

-12 + 5 + 16m + -1m = -52

$\large\texttt{Combine like terms: }$

-12 + 5 = -7

-7 + 16m + -1m = -52

$\large\texttt{Combine like terms: }$

16m + -1m = 15m

-7 + 15m = -52

$\large\texttt{Solving: }$

-7 + 15m = -52

-7 + 7 + 15m = -52 + 7

$\large\texttt{Combine like terms: }$

-7 + 7 = 0

0 + 15m = -52 + 7

15m = -52 + 7

$\large\texttt{Combine like terms: }$

-52 + 7 = -45

15m = -45

$\large\texttt{Divide each side by '15'. }$

15m ÷ 15 = -45 ÷ 15

m = -3

$\large\texttt{Simplifying: }$

m = -3

Identify the initial amount a and the growth factor b In the exponential function f(x)=620•7.8x

svetlana [45]

Given:

f(x) = 620e^7.8x

The standard equation for an exponential function is f(x) = Aoe^bx

where Ao is the initial amount
b is the growth factor

so, in this case, the initial amount is 620 and the growth factor is 7.8
