the numbers are 6 and 13

let x be one of the numbers then the other is 2x + 1

their sum increased by 7 = 26

x + 2x + 1 + 7 = 26

3x + 8 = 26

subtract 8 from both sides

3x = 26 - 8 = 18

divide both sides by 3

x = $\frac{18}{3}$ = 6

the numbers are 6 and (2 × 6) + 1 = 12 + 1 = 13

The distance from Earth to the sun is about 9.3 × 10 7th power miles.

AURORKA [14]

<u>Answer:</u>

The distance from earth to sun is 387.5 times greater than distance from earth to moon.

<u>Solution:</u>

Given, the distance from Earth to the sun is about $9.3 \times 10^{7} \mathrm{miles}$

The distance from Earth to the Moon is about $2.4 \times 10^{5} \mathrm{miles}$

We have to find how many times greater is the distance from Earth to the Sun than Earth to the Moon?

For that, we just have to divide the distance between earth and sun with distance between earth to moon.

Let the factor by which distance is greater be d.

$\text { Now, } \mathrm{d}=\frac{\text { distance between sun and earth }}{\text { distance between moon and earth }}=\frac{9.3 \times 10^{7}}{2.4 \times 10^{5}}=\frac{9.3}{2.4} \times 10^{7-5}\\\\=3.875 \times 10^{2}=387.5$

Hence, the distance from earth to sun is 387.5 times greater than distance from earth to moon.

The angle between 0 and 2π in radians that is coterminal with the angle 41/6π in radians is?

Inessa05 [86]

Answer:

5π/6

Step-by-step explanation:

Subtract multiples of 2π until you find the angle in the desired range.

41π/6 -36π/6 = 5π/6

The angle 5π/6 is co-terminal with 41π/6.

Answer:

Step-by-step explanation:

f(X)= 7-2x

f(3) means u have to put the value of 3 in the given equation so it will be

= 7-2×3

= 7-6

= 1

and now you have to add 6 to it so it will be 7.
