yes

420 /d = 30

multiply by d

420 =30d

divide by 30

14 =d

no d=14

37+s = 80/2

37+s =40

subtract 37 from each side

s =3

no s=3

52+g =45+11

52+g = 56

subtract 52 from each side

g=4

no g=4

13+14 = 3f

27 = 3f

divide by 3

Your favorite local band is selling merchandise and they have asked you to write an algebraic expression to represent their tota

Yuki888 [10]

Answer:

15t + 5c = b
$275

Step-by-step explanation:

Let "t' be the number of t-shirts bought.

Let "c" be the number of CDs bought.

Let b" be the total cost.

15t + 5c = b

We buy 10 t-shirts so t = 10.

We buy 25 CDs so c = 25.

We are trying to find b.

15t + 5c = b

15(10) + 5(25) = b

150 + 125 = b

275 = b

Best of Luck!

<h2> Question # 3</h2>

Answer:

$x = 13.094$

Step-by-Step Explanation

Considering the exponential equation

$e^{x-9}-6=54$

Solving the exponentiation equation

$e^{x-9}-6=54$

$\mathrm{Add\:}6\mathrm{\:to\:both\:sides}$

$e^{x-9}-6+6=54+6$

$e^{x-9}=60$

$\mathrm{If\:}f\left(x\right)=g\left(x\right)\mathrm{,\:then\:}\ln \left(f\left(x\right)\right)=\ln \left(g\left(x\right)\right)$

$\ln \left(e^{x-9}\right)=\ln \left(60\right)$

$\mathrm{Apply\:log\:rule}:\quad \log _a\left(x^b\right)=b\cdot \log _a\left(x\right)$

$\ln \left(e^{x-9}\right)=\left(x-9\right)\ln \left(e\right)$

$\left(x-9\right)\ln \left(e\right)=\ln \left(60\right)$

$\mathrm{Apply\:log\:rule}:\quad \log _a\left(a\right)=1$

$\ln \left(e\right)=1$

$x-9=\ln \left(60\right)$

$x=\ln \left(60\right)+9$

$x=13.094$ ∵ $\ln \left(60\right)=4.094$

Therefore, x = 13.094

<h2> Question # 4</h2>

Answer:

$x=0.386$

Step-by-Step Explanation

Considering the exponential equation

$3e^{9x}-6=91$

Solving the exponentiation equation

$3e^{9x}-6=91$

$\mathrm{Add\:}6\mathrm{\:to\:both\:sides}$

$3e^{9x}=97$

$\mathrm{Divide\:both\:sides\:by\:}3$

$\frac{3e^{9x}}{3}=\frac{97}{3}$

$e^{9x}=\frac{97}{3}$

$\mathrm{If\:}f\left(x\right)=g\left(x\right)\mathrm{,\:then\:}\ln \left(f\left(x\right)\right)=\ln \left(g\left(x\right)\right)$

$\ln \left(e^{9x}\right)=9x\ln \left(e\right)$

$9x\ln \left(e\right)=\ln \left(\frac{97}{3}\right)$

$\mathrm{Apply\:log\:rule}:\quad \log _a\left(a\right)=1$

$\ln \left(e\right)=1$

$9x=\ln \left(\frac{97}{3}\right)$

$\mathrm{Divide\:both\:sides\:by\:}9$

$\frac{9x}{9}=\frac{\ln \left(\frac{97}{3}\right)}{9}$

$x=\frac{\ln \left(\frac{97}{3}\right)}{9}$

$x=\frac{3.476}{9}$ ∵ $ln\left(\frac{97}{3}\right)=3.476$

$x=0.386$

Therefore, x = 0.386
