Answer:

Step-by-step explanation:

60% * x = 45% * 80

Changing to decimal form

.60x = .45 *80

.60x =36

Divide each side by .60

.60x/.60 = 36/.60

x =60

Simplify the equation. (5xE2 - 3x) - (5xE2 - 3x+1)

s2008m [1.1K]

Answer:

$\huge \boxed{\mathrm{-1}}$

Step-by-step explanation:

$(5xe^2 - 3x) - (5xe^2 - 3x+1)$

Distribute negative sign.

$5xe^2 - 3x- 5xe^2 +3x-1$

Combine like terms.

$0xe^2 +0x-1$

$0-1=-1$

Find the area of each figure below

Ugo [173]

Answer:

25. $27a^{3}b^{2}$

26. $3\pi x^{3}y$

Step-by-step explanation:

For 25:

$A = \frac{a+b}{2} h$ (area of a trapezoid)

$A=\frac{11a^{2}b+7a^{2}b}{2} *3ab$ (substitute terms)

$= \frac{18a^{2}b}{2}*3ab$ (collect like terms)

$= 9a^{2}b*3ab$ (reduce the fraction by crossing out 2)

$= 27a^{3}b^{2}$ (calculate)

For 26:

$A=\pi r^{2}$ (equation of area of a circle)

$A=\pi (3x^{3} y)^{2}$ (enter the radius)

$= 3\pi x^{3} y$ (communtative property to reorder the terms)

Can anyone help not understanding? And can you explain how you got it. Thanks for all your help!

Allushta [10]

No, the height wouldn't be 70 feet, it would be 80 feet.

You would get this answer by using the equation h= A/b (h meaning height)
A = area ( or 20,000)
b= base ( or 250)

Then you divide A by b:
20,000/ 250 =
80

I hoped this helped! :)
