Answer:

122 degrees

Step-by-step explanation:

Find the diagram attached. From the diagram;

<DEG + <GEF = <DEF

If the measure of angle GEF is thirteen less than five times measure of angle DEG, this is expressed as;

<GEF = 5<DEG - 13

Substitute

<DEG + <GEF = <DEF

<DEG +  5DEG - 13 = <DEF

6<DEG - 13 = <DEF

6<DEG - 13 = 149

6<DEG = 149 + 13

6<DEG = 162

<DEG = 27

Since <GEF = 5<DEG - 13

<GEF = 5(27) - 13

<GEF = 135-13

<GEF = 122 degrees

Hence the measure of angle GEF is 122degrees

def=149

gef=5x-13

deg=x

5x-13+x=149

6x=162

x=27

plug the x back in

5(27)-13=122

Answer:

x = 12

Step-by-step explanation:

The sum of a heptagon interior angles is 900 degrees, so:

10x + 5 + 12x - 9 + 9x + 14 + 133 + 10x + 9 + 10x + 136 = 900

rearrange to make it easier to subtract/add, u don't have to do this it's optional

10x + 12x + 9x + 10x + 10x + 5 - 9 + 9 + 14 + 133 + 136 = 900

add liket terms

22x + 29x + 19 + 269 = 900

51x + 288 = 900

subtract 288 from both sides

51x = 612

divide by 51

x = 12

Answer:

No values of x- Any whole number that is not 8

All values of x: 8

Just one Value of x: There could be many possibilites but all of them have to be some value of x. One answer is:x

Step-by-step explanation:

3x + 8 = 3x + x, which has one solution at x=8.

The given equation is 3x+8=3x+ ____.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

If 3x + 8 = 3x + 7 has no solutions

If 3x + 8 = 3x + 8 has infinite solutions

If 3x + 8 = 3x + x is equal to 3x + 8 = 4x, which has one solution at x=8

Therefore, 3x + 8 = 3x + x, which has one solution at x=8.

Look at the values on the axes of the graph.

Step-by-step explanation:

Domain can be found by looking at the x-axis of a graph. Range can be found by looking at the y-axis of a graph. You have to find at what point on the axis is the graph stopping.

For example, if I wanted the domain of y=x, I would say it is all real numbers. Why? Because when we look along the x-axis, from left to right, we can see that it continues going until infinity. That means that there are no stopping points in the graph of y=x.

B.- [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

The common difference is the difference between the numbers in your arithmetic sequence. In this case, we see that the numbers are getting smaller, so we can start by setting up this equation:

[tex]\frac{2}{3} - \frac{1}{6}[/tex]

Because these fractions don't have a common denominator, you make them equal by changing the fractions to have a common denominator. The LCM is 6, so we multiply the first fraction by 2/2:

[tex]\frac{4}{6} - \frac{1}{6} = \frac{3}{6}[/tex]

3/6 can be simplified to be 1/2, and we know we're subtracting, so the answer is b.

Answer:

d) 4/17

Step-by-step explanation:

14 of each suit, out of 52 total cards.

14/52 would be the chance to draw a diamond.

but, since you removed a card, you change the probability.

13 - 1 = 12

52 - 1 = 51

the probability that you will choose another diamond is 12/51

however, this can be simplified.

12 & 51 are both divisible by 3.

12/3 = 4

51/3 = 17

so the simplified answer would be 4/17

Answer:

The food will last for 16 days

Step-by-step explanation:

Proportions

We need to know how the variables depend on each other.

It's clear that:

The more campers, the more food the camp needs.

The more time, the more food the camp needs.

Therefore, the amount of food (F) is directly proportional to the number of campers (c) and the time (t).

This can be written as:

F = k.c.t

Where k is a constant that we'll be found by knowing the camp needs F=900 Kg of food for c=40 campers and t=20 days:

900 = k*40*20=800k

Thus:

k=9/8

And:

F = 9/8 c.t

We now need to find how many days will F=540 kg of food will last for c=30 campers. So we solve the equation for t:

t = 8/9 * F/c

t = 8/9 * 540/30

t = 16 days

The food will last for 16 days
