8x -(-5) = 29 To make the equation true, what is the value of x?

Answers

X=3 move constant to the right-hand side and change its sign
Subtract the numbers
Divide both sides by 8

Answer:

X = 3

Step-by-step explanation:

-(-5) is also the same as + 5, so the equation would be 8x + 5 = 29

Subtract 5 from both side of the equation

8x+5-5 = 29 -5

8x = 24

Then divide both sides by 8

Answers

Answer:

Factor: 1 [tex]\frac{1}{32}[/tex]

Decimal: 1.03125

Step-by-step explanation:

4 [tex]\frac{1}{8}[/tex] ×[tex]\frac{1}{4}[/tex]

Multiply 4 and 8 to get 32.

[tex]\frac{32+1}{8}[/tex] × [tex](\frac{1}4})[/tex]

Add 32 and 1 to get 33.

[tex]\frac{33}{8}[/tex] × [tex](\frac{1}{4})[/tex]

Multiply [tex]\frac{33}{8}[/tex] times [tex]\frac{1}{4}[/tex] by multiplying numerator times numerator and denominator times denominator.

[tex]\frac{33x1}{8x4}[/tex]

Do the multiplications in the fraction

[tex]\frac{33x1}{8x4}[/tex]

[tex]\frac{33}{32}[/tex]

Then simplify and you get

The volume of a cylinder is 90 pi cm^3 . If the radius is 3cm, what is the height of the cylinder?
(pythagorean theorem)
Please help Ill give brainlist

Answers

Answer:

A) 10 cm

Step-by-step explanation:

You don't need the Pythagorean Theorem. You can simply use the formula for the volume of a cylinder and solve for the height:

[tex]V=\pi r^2h\\\\90\pi=\pi (3)^2h\\\\90\pi=9\pi h\\\\10=h[/tex]

Therefore, the height of the cylinder is 10 cm.

r=3cmh=?

[tex]\\ \tt\hookrightarrow V=\pi r^2h[/tex]

[tex]\\ \tt\hookrightarrow 3^2\pi h=90\pi[/tex]

[tex]\\ \tt\hookrightarrow \pi h=10\pi[/tex]

[tex]\\ \tt\hookrightarrow h=10cm[/tex]

I was told the answer is D but not sure why. How do I figure it out?

Answers

Check the picture below.

the area of the region in white, is really the area of a trapezoid that has a height = 2, and bases of 3 and 6, so let's get its area

[tex]\textit{area of a trapezoid}\\\\ A=\cfrac{h(a+b)}{2}~~ \begin{cases} h=height\\ a,b=\stackrel{parallel~sides}{bases}\\[-0.5em] \hrulefill\\ h=2\\ a=3\\ b=6 \end{cases}\implies A=\cfrac{2(3+6)}{2}\implies A=9[/tex]

now that we know the area in white, let's check all expressions, and whichever does NOT result in 9, is it.

[tex]\boxed{A}\qquad (2)(6)-\cfrac{1}{2}(2)(3)\implies 12-3\implies 9 \\\\\\ \boxed{B}\qquad (4)(6)-\cfrac{1}{2}(4)(3)-2(3)-\cfrac{1}{2}(3)(2)\implies 24-6-6-3\implies 9 \\\\\\ \boxed{C}\qquad (3)(2)+\cfrac{1}{2}(3)(2)\implies 6+3\implies 9 \\\\\\ \boxed{D}\qquad (6)(2)+\cfrac{1}{2}(3)(4)\implies 12+6\implies 18\qquad \textit{\Large \checkmark}[/tex]
