Answer:

x = 1/2 or 0.5

Step-by-step explanation:

Subtract 2 from both sides of the equation

x + 2 - 2 = 5x -2

Simplify

x = 5x -2

Subtract 5x from both sides of the equation

x = 5x -2

x - 5x = 5x - 2 - 5x

Solution

x = 1/2

Hope this helps!! :))

Help, I tried it, but I keep getting the wrong answers

Aneli [31]

Answer:

my answer would be that

x = 17.91cm

(i'm not sure about it either but it's worth a try) !!

Step-by-step explanation:

so first off, using the equation given,

" c² = a² + b² — 2ab cos C "

we substitute the values in as,

a = 16

b = 30

then for C is the angle given, which is 30°

so the equation is now,

c² = (16)² + (30)² — 2(16)(30) cos 30°

now, you solve the two squared numbers and the back equation, also known as " 2ab cos C " with your scientific calculator.

so it now equals to,

c² = 256 + 900 — 960(0.87)

c² = 320.8

at last, when you have " c² = 320.8 " ,

remember to square root the answer so you have a smaller value.

so,

c equals to

$\sqrt{320.8}$

your final answer for the x value will be 17.91

(i hope this helps!)

Answer:

x = - 2, x = 3

Step-by-step explanation:

Given

x² - x - 6 = 0

Consider the factors of the constant term (- 6) which sum to give the coefficient of the x- term (- 1)

The factors are + 2 and - 3 , since

2 × - 3 = - 6 and 2 - 3 = - 1 , then

(x + 2)(x - 3) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

x - 3 = 0 ⇒ x = 3

Pythagorean theorem

marta [7]

Answer:

x = 8

Step-by-step explanation:

$a^{2} +b^{2} =c^{2} \\$ so $8^{2} +b^{2} =\sqrt{80} ^{2}$

rearrange the formula:

$\sqrt{80} ^{2} - 8^{2} = b^{2}$

$80 - 64 = b^2$

$b^2 = 16\\$ $b = \sqrt{16}$

$\sqrt{16} = 4$

$x = 4+4 = 8$

Jackson can lay 6000 ft² of tile in 3 h. What is Jackson’s tile-laying rate?

pickupchik [31]

divide 6000 by 3

6000 / 3 = 2000

so he can do 2000 sq ft per hour
