What is the average of 139 and 78?

Answer:

Miguel has video games = 14

Beth has video games = 10

Step-by-step explanation:

Miguel has video games = m

Beth has video games = b

We make the equations:

m=b+4 (Miguel has  4 more video games than Beth)

m+b=24 (together they have a total of 24 video games)

So, the system of equations is:

[tex]m=b+4\\m+b=24[/tex]

Now, solving these system of equations to find values of m and b

Let:

[tex]m=b+4--eq(1)\\m+b=24--eq(2)[/tex]

Put value of m from equation 1 into equation 2

[tex]m+b=24\\b+4+b=24\\2b=24-4\\2b=20\\b=\frac{20}{2}\\b=10[/tex]

We get value of b: b=10

Now, finding value of m by putting value of b in equation 1

[tex]m=b+4\\m=10+4\\m=14[/tex]

So, We get value of m: m= 14

Therefore:

Miguel has video games = m = 14

Beth has video games = b = 10

Answer:

m+b=24

m=b+4

Answer:

What is the sum of the exterior angles in a regular 15-gon?

The sum of the exterior angles in any convex polygon, including a regular 15-gon, is 360∘.

Step-by-step explanation:

thank me later

mark me as brainliest please

Answer:

5 exterior angles.

Step-by-step explanation: since they all have to add to 360 you can divide 360/5 = 72. You can also check by adding one interior angle plus 72 and checking if you get 180.

The point is (-1,5) and (0,0) also satisfies the given inequalities

The solution of the given inequalities

(x, y) = (4 , -2 )

Step-by-step explanation:

Step(i):-

Given system of equations are

3x + 2y < 8

-5x - 9y > -2

The solution of the given equations are

3x + 2y = 8   multiply '5'

-5x - 9y = -2 multiply '3'

       15 x + 10 y = 40  ...(i)

       -15x - 27 y = -6.....(ii)

Adding (i) and (ii) , we get

          - 17 y = 34

                y = -2

Substitute y = -2 in equation 3x + 2y =8

          3x - 4 =8

             3x = 12

               x =4

The solution of the given system of inequalities

(x, y) = (4 , -2 )

Step(ii):-

                   3x + 2y < 8

                  -5x - 9y > -2

The point is (-1,5)

                 -3 + 10 < 8

                    7 < 8

                5 - 45 > -2

                   -40 > -2

The point (0,0) also satisfies the given inequalities

Final answer :-

The point is (-1,5) and (0,0) also satisfies the given inequalities

Answer:

∠W = 16.3°

Step-by-step explanation:

In ΔVWX, v = 64 cm, w = 18 cm and x=63 cm. Find the measure of ∠W to the nearest degree.

From that above question, we are given 3 sides and we are to find the angle of one of the sides.

We solve using Cosine rule.

∠W = arc cos (v² + x²﹣w²/2vx)

∠W = arc cos (64² + 63² - 18² /2 × 64 × 63)

∠W = arc cos (0.9599454365)

∠W = 16.27137°

∠W = 16.3°

Answer:

I'm pretty sure it would be $131.56

Step-by-step explanation:

I think it will be $131.56 because if you take an multiply the 2.99 times  88 the number of muffins that were sold that day, then you would get $263.12. If you donated 1/2 of the profits made, then you would take 263.12 and divide it by 2 because half of it would be divided by 2. So therefore you would get $131.56! Hope this helps!

Correct me if I'm wrong!

Answer:

$698

Step-by-step explanation:

Given that :

Principal = $5600

Rate = 4.75%

Time = 3 years

Simple interest = principal * rate * time

Simple interest = $5600 * 0.0475 * 3

simple interest = $798

Step-by-step explanation:

|| represents the absolute value function:

|x| = x when x >= 0,

|x| = -x when x < 0.

Therefore (-8) * |2| = (-8) * 2 = -16. (A)

Answer:

Step-by-step explanation:

In step 1: mode will be solved so |2| will be absolute positive value of 2  which is 2

Step 2: multiply by -8  which is -16

So Answer is (A) -16

Given:

Jada traveled 135 miles in 3 hours.

Andre traveled 228 miles in 6 hours. Both Jada and Andre traveled at a constant speed.

To find:

How far did Jada travel in 1 hour?

Solution:

We have,

Distance traveled by Jada in 3 hours = 135 miles

Then,

Distance traveled by Jada in 1 hour = [tex]\dfrac{135}{3}[/tex] miles

                                                           = 45 miles

Therefore, Jada travel 45 miles in 1 hour.

Answer:

You will earn $323.4 per week

Step-by-step explanation:

We are given:

Cost per hour = $13.20

Number of hours you work each week = 24.5 hours

We need to find how much money do you earn per week.

Amount of money you earned per week = Cost per hour * Number of hours worked

Amount of money you earned per week = 13.20 * 24.5

Amount of money you earned per week = 323.4

So, you will earn $323.4 per week
