Ethan puts $50 on his school lunch card. He buys the same $5 lunch every day. Which equation shows the balance, b, on his card in terms of the number, m, of meals he has
purchased?

Answer:

[tex] - {4} < x < - 6 \\ [/tex]

Step-by-step explanation:

[tex]5 < - 4x - 11 < 13[/tex]

Add 11 to both sides of the inequality to make - 4x stand alone

[tex]5 + 11 < - 4x - 11 + 11 < 13 + 11 \\ 16 < - 4x < 24[/tex]

Divide both sides by - 4

[tex] - \frac{16}{4} < \frac{ - 4x}{ - 4} < - \frac{24}{4} \\ - {4} < x < - 6[/tex]

Reverse the signs

We have the final answer as

[tex] - 4 > x > - 6 \\ [/tex]

Step-by-step explanation:

I had the same one on my quiz

[tex]( {p}^{6} {q}^{ \frac{3}{2} } {)}^{ \frac{1}{3} } \\ = ( {p}^{6 \times \frac{1}{3} } ).( {q}^{ \frac{3}{2} \times \frac{1}{3} } ) \\ = ( {p}^{2} ).( {q}^{ \frac{1}{2} } ) \\ = {p}^{2} {q}^{ \frac{1}{2} } [/tex]

Answer:

x+3x+90=360(sum of complete turn)

4x=360-90

4x=270

x=270/4= 67.5

Step-by-step explanation:

Answer:

5y+9x is the simplified version

Question: +6 charge and -6 charge

Question 2: 8 units to the left of 4

(4 - 8 = -4 and 8 units left is -4)

Question 3: 4

(7 +(-3) is essentially 7-3 which equals 4 because negative takes over the positive)

Question 5: 1/-6

(it doesn't matter if the negative symbol is on top or bottom, numerator or denominator just the numbers have to stay in the same place)

Question 4: -45

(4.5 times 5 is 22.5, and 22.5 times -2 is -45, the negative takes over the positive)

Question 6: 2m-4

( 2(m-5) +6

distribute first

2 times m = 2m

2 times -5 = -10

so now you have 2m - 10 + 6

combine like terms to get 2m - 4

(-10 + 6 = -4)

Answer:

[tex]10+5\sqrt{3}[/tex]

Step-by-step explanation:

Given the expression: 5 / (2 - √3)

To rationalize the denominator, we multiply the numerator and denominator by the conjugate of the denominator. The conjugate of (2 - √3) is (2 + √3). Hence multiplying gives:

[tex]\frac{5}{2-\sqrt{3} }*\frac{2+\sqrt{3}}{2+\sqrt{3}} \\\\=\frac{10+5\sqrt{3} }{4+2\sqrt{3}-2\sqrt{3}-3 }\\\\Simplifying\ the\ expression:\\\\ =\frac{10+5\sqrt{3} }{1}\\\\= 10+5\sqrt{3}[/tex]

Hence: 5 / (2 - √3) = [tex]10+5\sqrt{3}[/tex]

Answer:

Red sweets = 21

Step-by-step explanation:

Let there are 3x red sweets and 7x green sweets.

Total no of 49 green sweets.

ATQ,

7x = 49

x = 7

Red sweets = 3x

= 3(7)

= 21

Hence, there are 21 red sweets.

$47,600 Spent on home repairs

Step-by-step explanation:

So we know that Devon is spending 12 percent of the home cost on repairs

We know the home cost is 42,500

So we just add 12 percent to the bundle

We know 42,500 is 100 percent of the price

And we want to add another 12 percent since the question is asking for the total amount spent on homes

So initially we just multiply 42,500 by 112% or 1.12

Now just multiply

You’ll get 47,600

Answer:

4 weeks

$28

Step-by-step explanation:

Let

x = number of weeks

Jamal's savings = 18 + 5x

Samuel's savings = 10 + 7x

Equate both savings

Jamal's savings = Samuel's savings

18 + 5x = 10 + 7x

18 - 10 = 7x - 5x

8 = 2x

x = 8 / 2

= 4

x = 4 weeks

Check:

18 + 5x

18 + 5(2)

18 + 10

= $28

Each boy would have saved an equal amount of $28 at the end of the 4th week

Answer:

Store A has a better deal

Step-by-step explanation:

Store A-

245x.25=61.25

245-61.25=183.75

Store A's sale price is $183.75

Store B-

166x.20=33.20

166+33.20= 199.20

Store B's new price is $199.20

Conclusion

$183.75 is less than $199.20 so store A has a better deal because you're paying less than what you would be paying at store B

Complete question :

You buy 3.9 pounds of trail mix. The mix costs ​$2.99 per pound. What is the total price for the trail​ mix?

Answer:

$11.661

Step-by-step explanation:

Given that :

Cost per pound of trail mix = $2.99

Pounds of trail mix purchased = 3.9 pounds

Total price of the trail mix :

(Cost per pound of trail mix * pounds of trail mix purchased)

($2.99 * 3.9 pounds)

= $11.661

The answer is 220%.

Answer: [tex]61.9miles/hr[/tex]

Step-by-step explanation:

given data:

distance travelled by the car =  195 miles

time taken = 3 hours and 15mins

solution

average speed of the car

[tex]= \frac{195miles}{3hrs15mins} \\\\= 61.9miles/hr[/tex]

Answer:

The average speed is [tex]v=60 miles/h[/tex]

Step-by-step explanation:

The equation of the average speed os given by:

[tex]v=\frac{\Delta x}{\Delta t}[/tex] (1)

here:

Δx is just 195 miles

Δt is the time traveled. 3.25 h ( 3 h + 15 min or 0.25 h)  

So we just need to put this into the equation (1)

[tex]v=\frac{195}{3.25}[/tex]

Therefore, the average speed is [tex]v=60 miles/h[/tex]

I hope it helps you!

Answer:

3

Step-by-step explanation:

f(x) = 4x^3 – 13x^2 + 9x + 2

This looks complicated but all we need to find are the Roots

We are looking for when y=0

So given each part of the information, we can label how many times it happens

The function starts from the bottom of quadrant 3: Starts lower left

and goes up through the x-axis at (0, negative 0.25) : This is ONE ROOT

and then through the y-axis at (0, 2). : It's now on the 2nd quartile

It then starts to curve down at (0.5, 4): It's moving towards y=0

until it reaches (1.75, negative 0.5).: It has now passed y=o and there are TWO ROOTS

It then curves up and crosses the x-axis at (2, 0) and goes up approaching x = 3: It has passed y=0 again, so there are THREE ROOTS

This polynomial function has 3 ROOTS
