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:

- 1.5

Step-by-step explanation:

I suggest to make a table

x       y

-2      3

2     -3

from 3 to -3, you subtract 6

from -2 to 2, you add 4

so y/x

-6/4 = -1.5

Slope is -1.5

Answer:

$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: [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

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

Answer:

No

Step-by-step explanation:

Given that:

Total number of cups of trail mix available for camping trip = [tex]6\frac{1}{2}[/tex]

Amount of one serving contains = [tex]\frac{3}{4}[/tex] cups

Number of people at the trip = 12

To find:

Whether each person will be able to get the servings?

Solution:

Here, we can find the total number of servings by dividing the total number of cups of trail mix with the amount of one serving.

First of all, let us convert the mixed fraction into fractional number.

[tex]6\dfrac{1}{2} = \dfrac{6\times 2+1}{2} = \dfrac{13}{2}[/tex]

Therefore, total number of servings available as per the given quantities:

[tex]\dfrac{\frac{13}2}{\frac{3}4}\\\Rightarrow \dfrac{13\times 4}{2\times 3} \\\Rightarrow \dfrac{26}{3}\\\Rightarrow \approx 8[/tex]

So, With this type of servings Zoey will be able to serve only 8 people.

Therefore, there is not enough servings.

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.

Step-by-step explanation:

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)
