Answer:

(7q-5)²

Step-by-step explanation:

= 49q² - 70q + 25

= 49q² -35q -35q + 25

= 7q(7q-5) - 5(7q - 5)

= (7q-5) (7q-5)

= (7q-5)²

CMIIW

Answer:

Step-by-step explanation:

49q² -70q +25 , rewrite the first two terms as squares

(7q)² -70q + 5² , compare with  a² - 2ab + b² = (a-b)²

    a² - 2ab + b²

(7q)² -2(7q)(5 )+ 5², because 70q = 2*35q = 2*7*5*q

We can see that a = 7q and b=5, therefore

49q² -70q +25 = (7q -5)²

We set the equation equal to 0 to find the roots

7q-5 =0, add 5 to both sides

7q =5 , divide both sides by 7

q = 5/7 ≈ 0.714

Answer:

$4.95

Step-by-step explanation:

Paul originally has $3.69.

His sister gives him $5.25.

$3.69 + $5.25 = $8.94

The CD single cost him $3.99

$8.94 - $3.99 = $4.95

Therefore, he has four dollars and 95 cents ($4.95) left.

Answer:

$4.95

Step-by-step explanation:

3.69+5.25= 8.94

8.94-3.99=4.95

Answer:

the selling price = 1512

Step-by-step explanation:

the profit = 1200 × 26/100

= 312

the selling price = profit + the cost

= 1200+ 312 = 1512

Answer:

Yes it is a rational number

Answer:

Step-by-step explanation:

So, to go about your question, we must first ask, how many hours a week is being worked?

In this problem, that is 9 hours per week.

Next, we must question how much per week is made

That is $92 per week

Finally, we must determine if the allowance is occuring many times in the week or just once.

In this problem, that is only occuring once for the week.

So, the equation we must setup is 9x +20 =92.

To solve the equation, we need to subtract 20 on both sides to isolate the variable, x.

9x+20=92

     -20     -20

Now our equation is

9x=72

Now, to finally get x by itself or to isolate x, you should divide 9 on both sides to cancel out the 9 being multiplied by the x.

9x=72

9     9

x=8 because of 72/9 is equal to 8.

I hope this helps, and I will answer any questions you have.

Step-by-step explanation:

Answer:

Step-by-step explanation:

-3≤ 6x - 9                 Add 9 to both sides

-3 + 9 ≤ 6x               Combine left

6 ≤ 6x                       Divide by 6

6/6 ≤ 6x/6

1 ≤ x

6x - 9 < 39               Add 9 to both sides

6x < 39 + 9              Combine

6x < 48                     Divide by 6

6x/6 < 48/6

x < 8

So the inequality is

Answer:

1/10

Step-by-step explanation:

8 black marbles, 5 white marbles and 12 red marbles = 25 marbles

P(red) = red/total = 12/25

Remove the marble

8 black marbles, 5 white marbles and 11 red marbles = 24 marbles

P(white) = white/total = 5/24

P(red, remove,white) = 12/25 * 5/24

                                   =12/24 * 5/25

                                   =1/2 * 1/5

                                   =1/10

Step-by-step explanation:

Total balls = 12 + 5 + 8 = 25 marbles

Probability of getting white marbles = 5/24

Probability of red marbles = 12/24 = 1/2

Now

Probability = 1/2 × 5/24 + 1

Probability = 1/2 × 5/25

Probability = 5/50

Probability = ⅒

Answer:

Step-by-step explanation:

The exponential model for the given points is y = 6.88(1.47)ˣ

In mathematics, an exponential function is a function of form f (x) = aˣ, where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0.

Given,

points are (8,150) and (9,220)

Exponential function,

y = abˣ            --------(A)

for point (8 , 150)

150 = ab⁸    -------(1)

for point (9 , 220)

220 = ab⁹    -------(2)

Dividing equation (2) by equation (1)

220/150 = ab⁹/ab⁸

Simplifying

1.47 = b

Substituting value of b in equation (1)

150 = a(1.47)⁸

150 = a(21.80)

a = 150/21.80

a = 6.88

Substituting value of a and b in equation(A)

y = 6.88(1.47)ˣ

Hence, y = 6.88(1.47)ˣ is the exponential model for given points.

Answer:

$850

Step-by-step explanation:

washer + dryer = $950

if washer cost=>$100

Therefore; the value of the dryer should be x

$100+x=$950

x=$850

The dryer cost is =>$850

Answer:

The dryer is $425.

Step-by-step explanation:

Washer = 100 + Dryer

Set up an equation:

Variable x = dryer

x + x + 100 = 950

x + x = 850

2x = 850

x = 425

Dryer = 425

Bonus answer:

Washer = 100 + x

Washer = 100 + 425

Washer = 525

Check your work:

Washer + Dryer = 950

525 + 425 = 950

Answer:

9 nickels

Step-by-step explanation:

Answer:

9 nickels

Step-by-step explanation:

He doesn't have that many coins, and there are 4 choices, so let's use the guess method.

Try 7 nickels.

7 * $0.05 = $0.35

16 - 7 = 9

9 * $0.25 = $2.25

The quarters alone are worth more than $2.20, so this is not the answer. We need more nickels and fewer quarters.

Try 11 nickels.

11 * $0.05 = $0.55

16 - 11 = 5

5 * $0.25 = $1.25

$0.55 + $1.25 = $1.80

The coins are worth too little. We need fewer nickels and more quarters.

Try 9 nickels.

9 * $0.05 = $0.45

16 - 9 = 7

7 * $0.25 = $1.75

$0.45 + $1.75 = $2.20

The coins are worth the correct amount.
