Answer:

Graph 3

Step-by-step explanation:

Given : Jamal earns $7 an hour Helping his neighbors.

             He wants to earn more than $105 altogether.

             He has already earned $63.

To Find:  Which graph shows the remaining number of hours Jamall could work to earn more than $105?

Solution:

Let x be the number of  the remaining number of hours Jamal could work to earn more than $105.

He earns in 1 hour = $7

He earns ion x hours = $7x

He already has money = $63

He wants to earn more than $105 altogether

So, equation becomes : 63+7x\geq 105

7x\geq 105-63

7x\geq 42

x\geq \frac{42}{7}

x\geq 6

Thus the remaining number of hours Jamal could work to earn more than $105 must be 6 or more than 6 hours .

Since 6 is included . So, Graph 3 is correct.

Hence Graph 3 shows the remaining number of hours Jamal could work to earn more than $105 must be 6 or more than 6 hours.

Your inequality is 63 + 7h is equal or greater than 105. Subtract 63 to both sides to get 7h is greater than or equal to 42. 42/7 = 6, so the answer is 6 or greater. The answer is the third one. Hope this helped, and have a great day!

Which expressions are equivalent to 5(-2k-3)+2k
bulgar [2K]

Answer:

-8k - 15

Step-by-step explanation:

5(-2k-3)+2k

At first, we will break the parenthesis. To break that, we will multiply the value inside the parenthesis by the adjacent number, that is 5. Again, we have to consider the Algebraic operation (Golden rule) -

[(-) x (-) = (+); (+) x (-) = (-)]

Therefore, since there is a minus sign in each of the value inside the parenthesis, the result will be minus as 5 is a positive integer.

or, -5*(2k) - (5*3) + 2k

or, -10k - 15 + 2k

or, -8k - 15 (after the deduction)

The answer is = -8k - 15

A regular hexagon is inscribed in a circle and another regular hexagon is circumscribed about the same circle. What is the ratio
Anna007 [38]

4/3 of the area of the larger hexagon to the area of the smaller hexagon

Let the sides of the interior hexagon be 2 cm long, then this hexagon is made up of 6 equilateral triangles of side = 2.

The area of this hexagon = 6 * 1 * sqrt3 = 6 sqrt3 ( as the triangle is made up of 2 60-30-90 triangles)

The exterior hexagon is made up of 6 equilateral triangles with altitude 2 and the area = 6 * 2 * (2 / sqrt3 ) = 24 / sqrt3

area exterior hex / interior hex = 24 / sqrt3 * 1 / 6sqrt3 = 24/18

= 4/3

Required ratio = 4/3 answer
