Miguel and Beth like to play video games together. Miguel has m video games, and Beth has b video games. Miguel has
4 more video games than Beth, and together they have a total of 24 video games. Which system of equations can be
used to find how many video games belong to each friend?

Answers

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

Jada traveled 135 miles in 3 hours. Andre traveled 228 miles in 6 hours. Both Jada and Andre traveled at a constant speed. A) How far did Jada travel in 1 hour?

Answers

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.

the cost for a bakery to make a dozen muffins is 2.52. the sale price of an individual muffin is 2.99. for one day, the bakery will donate 1/2 of the profits from muffin sales to charity. what is the bakeries donation, in dollars, if 88 muffins are sold that day

Answers

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!

Answers

Answer:

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

A batch has 15000 coloured bulbs. 3/5 of the batch are orange in colour & the rest are green . if 1/8 th of the green bulbs are not working , how many green bulbs are functional?

Answers

Answer:

5250 bulbs are functional green bulbs

Step-by-step explanation:

find out how much 1/5 of 15000 is

15000/5=3000

find out how many are orange

3/5=1/5+1/5+1/5 3000*3=9000

of the 15000 bulbs 9000 are orange the rest are green find the amount that is left over

15000-9000=6000 bulbs are green

find out what 1/8 of the green bulbs is

6000/8=750

1/8 or 750 green bulbs are not working

find out how many bulbs are functional

6000-750=5250 bulbs are functional green bulbs
