The answer is W= -4

-7w+5(w-6)=-22
Distribute:
-7w+5w-30=-22
Combine like terms:
-2w-30=-22
Add 30 on both sides:
-2w=8
Divide by -2 on both sides
W=-4

Answer:

w = -4

Step-by-step explanation:

Solve for w:

5 (w - 6) - 7 w = -22

5 (w - 6) = 5 w - 30:

5 w - 30 - 7 w = -22

Grouping like terms, 5 w - 7 w - 30 = (5 w - 7 w) - 30:

(5 w - 7 w) - 30 = -22

5 w - 7 w = -2 w:

-2 w - 30 = -22

Add 30 to both sides:

(30 - 30) - 2 w = 30 - 22

30 - 30 = 0:

-2 w = 30 - 22

30 - 22 = 8:

-2 w = 8

Divide both sides of -2 w = 8 by -2:

(-2 w)/(-2) = 8/(-2)

(-2)/(-2) = 1:

w = 8/(-2)

The gcd of 8 and -2 is 2, so 8/(-2) = (2×4)/(2 (-1)) = 2/2×4/(-1) = 4/(-1):

w = 4/(-1)

Multiply numerator and denominator of 4/(-1) by -1:

Answer: w = -4

The average distance from the sun to the planet Mercury is about 58,000,000 km. The diameter of a human hair is about 0.0025 cm.
Anna [14]

Answer:

Distance of Sun and Mercury = 58,000,000 km.

In Scientific notation, it would be: 5.8 × 10⁷ Km

Diameter of a human hair = 0.0025 cm

In scientific notation, it would be: 2.5 × 10⁻³ cm

Before Comparison, we need to bring  to  or vice-versa, so we can easily calculate then, here, we will go from cm to Km.

2.5 × 10⁻³ × 10⁻⁵ Km = 2.5 × 10⁻⁸

Now, we can compare the values,  

5.8 × 10⁷ Km > 2.5 × 10⁻⁸

[ reason. - power of smaller number is in negative, it means, it is denominator, which would be very small as compared to other ]

I need help can I don’t know how to do this problem
Elden [556K]

Answer:

a ^ (1/12)

Step-by-step explanation:

a ^ (1/3)

---------------

a ^ (1/4)

We know that b^ c / b^ d = b ^ (c-d)

a^ (1/3 - 1/4)

getting a common denominator

1/3 *4/4 - 1/4*3/3 = 4/12 - 3/12

a^ (4/12 - 3/12)

a ^ (1/12)

Please help with these 3 pretty easy problems and explain how you got it!!! 100 POINTS AND BRAINLIEST!!!! Serious answers please
natita [175]

Answer:

Step-by-step explanation:

1)

(x-3)/18=12/9, cross multiply

9(x-3)=18(12)

9x-27=216, add 27 to each side

9x=243, divide each side by 9

x=27

2)

(x-16)/(x+6)=3/5, cross multiply

5(x-16)=3(x+6)

5x-80=3x+18, subtract 3x from each side

2x-80=18, add 80 to each side

2x=98, divide each side by 2

x=49

3)

Since the triangles are similar we can say that

25/(4x-1)=10/(x+5), cross multiply

25(x+5)=10(4x-1)

25x+125=40x-10, subtract 40x from each side

-15x+125=-10, subtract 125 from each side

-15x=-135, divide each side by -15

x=9
