The simplified form of the expression 7^x+1 + 7^x / 2×7^x as given in the task content follows from the laws of indices and is equal to; 4.

<h3>What is the simplified form of the expression 7^x+1 + 7^x / 2×7^x?</h3>

It follows from the task content that the expression whose simplified form is to be determined is given as; 7^x+1 + 7^x / 2×7^x.

On this note, it follows from the law of indices that; 7^x+1 = 7× 7^x.

Hence, we have; 7^x(7+1 ) / 2×7^x.

And upon simplification, we have; 8/2 = 4.

Consequently, we may conclude that the simplified form of the expression as given in the task content is; 4.

nika2105 [10]
This would mean that she has been in school for about 1,000 days. Thus, we need to figure out the amount of days she would have went to school within the week. This would normally be 5 days within the 7. 

5/100 x 1000 is 714.28

When rounded to the nearest ten, it would end up at 710.

Simplify the expression below.
natita [175]

Answer:

3m - 8

Step-by-step explanation:

Step by Step:

Equation= 6m³ - 16m² + 15m - 40/ 2m² + 5

Factor out 2m² from 6m³ - 16m²:

Factor out 5 from expression:

2m²(3m - 8) + 5(3m - 8)/2m² + 5

Factor out 3m - 8:

(3m - 8)(2m² + 5)/2m² + 5

Rude the fraction with 2m² + 5:

3m - 8 is the answer

I hope this helped!

two angles are consecutive exterior to one another. if the angles are in ratio 11:7. Then find the supplement of the larger angl
Gwar [14]

If the ratio of two consecutive exterior angles are 11:7, the supplement of the larger angle will be <u>70 degrees</u>.

The larger angle and the smaller angle are supplementary to each other since they are consecutive exterior to one another.

  • <em><u>Thus</u></em>:

If the larger angle is x, therefore:

Ratio of Larger angle to smaller angle = 11:7

  • <em>Therefore</em>:

11x + 7x = 180 degrees

  • Solve for x

18x = 180

  • Divide both sides by 18

x = 10

Larger angle = 11x = 11(10) = 110 degrees

Smaller angle = 7x = 7(10) = 70 degrees

The supplement of the larger angle, 110 degrees, is <u>70 degrees.</u>

In summary, if the ratio of two consecutive exterior angles are 11:7, the supplement of the larger angle will be <u>70 degrees</u>.
