Answer:

there

Step-by-step explanation:

T = 4 + 2A

S = 5A - 8

T = S

Since T and S are equal, set them against each other

2A + 4 = 5A - 8

Subtract 2A from each side, and add 8 to each side

12 = 3A

Divide each side by 3

A = 4

If Andrew is 4, then Tom is twice that plus 4, or 12. Sarah is 5 times 4 less 8, or 12.

A man is trying to calculate the shadow of a 24 flag pole. He uses similar triangles by comparing his own height 5 ft to the len
Pie

Answer:

The answer to your question is 12 ft

Step-by-step explanation:

Data

Height of the flag pole = 24

shadow of the flag pole = x

height of the man = 5 ft

shadow of the man = 2.5 ft

Process

1.- Use the Thales' theorem to solve this problem

shadow of the flag pole/height of the flag pole = shadow of the man/height

                                                                                                 of the man

- Substitution

                     x/24 = 2.5/5

- Solve for x

                    x = 2.5(24)/5

- Simplification

                    x = 60/5

-Result

                   x = 12 ft

Examine the system of equations. y = –3x – 2, y = 7 The value of x is . The solution to this system of equations is .
joja [24]
Hello!

You can substitute y into the other equation

7 = -3x - 2

Add 2 to both sides

9 = -3x

Divide both sides by -3

-3 = x

The answer is -3

Hope this helps!

How would you write the following expression as a single term? 3[2 ln(x-1) - lnx] + ln (x+1)
Elan Coil [88]

Apply the rule: n ln x = ln x^{n}

3[2 ln(x-1) - lnx] + ln(x+1)=3[ln(x-1)^{2} - lnx ] + ln(x+1)

Apply the rule : log a - log b = log \frac{a}{b}

3[2 ln(x-1) - lnx] + ln(x+1)=3ln\frac{(x-1)^{2} }{x} + ln(x+1)

Apply the rule: n ln x = ln x^{n}

3[ln (x-1)^{2} -ln x]+ln (x+1)= ln \frac{(x-1)^{6} }{x^{3} } +log(x+1)

Finally, apply the rule: log a + log b = log ab

3[ln(x-1)^{2} -ln x]+log(x+1)=ln\frac{(x-1)^{6}(x+1) }{x^{3} }
