<h2><em><u>Answ</u></em><em><u>er</u></em><em><u>:</u></em><em><u>-</u></em></h2>

<h3>1.) 3x + 2 = 15</h3>

➪ 3x = 15 - 2

➪ 3x = 13

★ \large\pink{x = \sf{\dfrac{13}{3}}}

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

<h3>2.) 5x - 8 = 52</h3>

➪ 5x = 52 + 8

➪ 5x = 60

➪ x = \sf\dfrac{60}{5}

★ \large\pink{x = 12}

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

<h3>3.) 2(x+1) = 14</h3>

➪ 2x + 2 = 14

➪ 2x = 14 - 2

➪ 2x = 12

➪ x = \sf\dfrac{12}{2}

★ \large\pink{x = 6}

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

<h3>4.) 1/4 x + 6 = 12</h3>

➪ \sf\dfrac{1}{4} \times x = 12 - 6

➪ \sf\dfrac{1}{4} \times x = 6

➪ \sf 1 \times x = 6 \times 4

★ \large\pink{x = 24}

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

<h3>5.) 1/5 + 2y = 2/5</h3>

➪ \sf 2y = \dfrac{2}{5} - \dfrac{1}{5}

➪ \sf 2y = \dfrac{2-1}{5}

➪ \sf 2y = \dfrac{1}{5}

➪ \sf y = \dfrac{1}{5 \times 2}

★ \large\pink{y = \dfrac{1}{10}}

1) y=mx+b (solve for b)<br>2) t=an+b (solve for n)
astra-53 [7]
The equation is already solved for the variable t To solve for any other variable simply rearrange theequation to have the indicated variable on one sideof the equals sign and everything else on the other. For example, to solve for a: t=an+b       subtract b from both sidest-b = an      divide both sides by n(t-b)/n = a Or:  a = (t-b)/n Work in the same manner to solve for either b or n: b = t-an n = (t-b)/a

Jacob consumes an energy drink that contains caffeine. After consuming the energy drink, the amount of caffeine in Jacob's body
sasho [114]

Answer: 0.87400mg of caffeine.

Step-by-step explanation:

You have

N(t)=N0(e^−rt)(1)

as a general Exponential decay equation where N0 is the amount at t=0, N(t) is the amount remaining at time t and r is the exponential decay constant. You're specifically given that after 10 hours, the decay factor is 0.2601, i.e.,

N(10)/N(0)=N0(e^−10r)/N0(e^0)= e^−10r=0.2601 . .(2)

Taking the last 2 parts of (2) to the power of 0.1t gives

e^−rt=0.2601^.1t . .(3)

This means that

N(t)=N0(e^−rt)=N0(0.2601^.1t). .(4)

Also,

N(2.56)N(1.56)=N0(0.2601.1(2.56))N0(0.2601.1(1.56))=0.2601.1(2.56−1.56)=0.2601^.1

= 0.87400mg of caffeine.
