Can someone walk me through how to do this, please? I forgot. Solve for a and z. x^8⋅x^3=ax^z

Solve for a by simplifying both sides of the equation, then isolating the variable.
a=x^11-z
Solve for z by creating equivalent expressions in the equation that all have equal bases, then solve for z.
z=11ln(x) divided by ln (a) + ln (x)

What is the answer? X/8 - 4 = 15/16

sukhopar [10]

Answer:

Step-by-step explanation:

$\dfrac{x}{8}-4=\dfrac{15}{16}\qquad\text{multiply both sides by 8}\\\\8\!\!\!\!\diagup^1\cdot\dfrac{x}{8\!\!\!\!\diagup_1}-(8)(4)=8\!\!\!\!\diagup^1\cdot\dfrac{15}{16\!\!\!\!\!\diagup_2}\\\\x-32=\dfrac{15}{2}\qquad\text{add 32 to both sides}\\\\x-32+32=7.5+32\\\\x=39.5$

Cecilia made an envelope to mail a letter. She colored the regular trapezoid flap on the bottom of the envelope blue, as shown.

podryga [215]

Answer:

The correct option is:

14 inches

Step-by-step explanation:

The question is incomplete because the picture of the flap is not shown in the question nor the measurements are given. First lets complete the question. The figure was this question is attached below.

We can see that the bottom width of the trapezoid is 9 inches, the top width of the trapezoid is 5 inches, and it has a height of 2 inches.

The area of trapezoid is given as:

Area = ((Top width + Bottom width)/2) · h

Area = ((9+5)/2) · 2

Area = (14/2) · 2

Area = 7 · 2

Area = 14 inch²

The sum of 11 and the product of 2 and a number r

andrew-mc [135]

Algebraically that would be expressed as 2r + 11

The product of 2 and r is 2r.

The sum of 2r and 11 is 2r + 11
