Answer: 5/96

Step-by-step explanation:

Answer: 60 quarters and 40 dimes

Step-by-step explanation:

Step 1: Setup Coin Value and Coin Total Equation:

Coin Value Equation → 0.1d + 0.25q = $19.00 where d = dimes and q = quarters

Coin Total Equation → d + q = 100

Step 2: Rearrange Coin Total Equation in terms of dimes (d)

d = 100 - q  ← Revised Coin Total Equation

Step 3: Plug in our Revised Coin Total Equation for d into our Coin Value Equation:

0.1(100 - q) + 0.25q = $19.00

0.1(100) - 0.1(q) + 0.25q = $19.00

10 - 0.1q + 0.25q = $19.00

10 + (0.25 - 0.1)q = $19.00

10 + 0.15q = $19.00

Step 4: Subtract 10 from each side of the equation to isolate q

10 - 10 + 0.15q = $19.00 - 10

0.15q = 9

Step 5: Divide each side of the equation by 0.15 to isolate q

0.15q/0.15  =    9/0.15

q = 60

Step 6: Using our value for q, Solve for d using our Coin Total Equation:

d + 60 = 100

Subtracting 60 from both sides, we get d + 60 - 60 = 100 - 60

d = 40

Summarizing our word problem, we see that 60 quarters and 40 dimes add up to $19.00

Answer:

ab - bc = 6

Step-by-step explanation:

COMPUTATION:

ab - bc = ?

(2 x -3) - (-3 x 4) = ?

(-6) - (-3 x 4) = ?

(-6) - (-12) = ?

Answer:

I put 4, 5, & 6 in order in the photos.

7-8-9 are all linear functions which are written in the y=ax+b format, the ones I put in bold are the equations and I listed the values just in case I'm not sure how your teacher makes you write them.

7.

-0.6=a(-3)+b

0.2=a(1)+b

1.4=a(7)+b

a=0.2,b=0

y=0.2x

8.

-10=a(-5)+b

-1=a(-2)+b

17=a(4)+b

b=5, a=3

y=3x+5

9.

8=a(-5)+b

2=a(-2)+b

-18=a(8)+b

b=-2, a=-2

y=-2x-2

10.

The domain and range is negative infinity to infinity.

For a basic subscription, a cable television provider charges an activation fee of $60, plus $125 per month. What linear function represents the total cost of basic cable subscription for t months? What is the total cost for two years of service?

y=125x+60

$310 for 2 months

$3060 for 2 years

Step-by-step explanation:  let x be the number of months

y=125x+60

y=125(2)+60

y=310 dollars for two months

y=125(24)+60

y=3060 dollars for two years

Answer:

15, 16, 17

Step-by-step explanation:

let the consecutive numbers be n , n + 1 , n+ 2 , then

n + n + 2 = 32 ( sum of first and third )

2n + 2 = 32 ( subtract 2 from both sides )

2n = 30 ( divide both sides by 2 )

n = 15

n + 1 = 15 + 1 = 16

n + 2 = 15 + 2 = 17

The 3 numbers are 15, 16, 17

Step-by-step explanation:

let the 1st and 2nd consecutive number be

x , x + 1 , x + 2

their sum = 32

so, x + x + 2 = 32

→ 2x + 2 = 32

→ 2x = 32 - 2 = 30

→ x = 30/2 = 15

so,

1st and 3rd consecutive number is

x = 15

x + 2 = 15 + 2 = 17

as they are consecutive number so 2nd number is 16

and a/q sum of 1st and 3rd number is 32

15 + 17 = 32

hope this answer helps you dear...take care and may u have a great day ahead!

Answer:

b = -20

Step-by-step explanation:

b + 2 = -18

b = -20

Answer:

b= -20

Step-by-step explanation:

the first step is to subtract 2 from both sides of the equation.

b + 2 = -18

   -2      -2

-------------------

the -2 and +2 cancel

b = -20

hope this helps! :D

Answer:

n=-6

Step-by-step explanation:

8n-7=-5(-3n-7)

Multiply -5 to -3n and -7

8n-7= 15n+35

Bring 8n to the other side by subracting it from 15n

-7=7n+35

Subtract 35 from both sides

-42=7n

Divide both sides by 7

n=-6

Answer:

12

Step-by-step explanation:

So, she practices 12 hrs per week, and already has practiced 3 hrs this week.

This means she has 9 hrs left to practice.

3/4 of an hour is one session, so to find out the number of sessions she needs, you have to do (9 hours)/(one session)

which is basically 9 / ( 3/4)

[tex]\frac{9}{3/4}=\frac{9}{1} / \frac{3}{4} = \frac{9}{1} * \frac{4}{3} = \frac{36}{3} = 12[/tex]

She needs 12 more sessions.

Answer:

6  pencils

Step-by-step explanation:

Total cost = paper * cost of a package + pencils * cost of a pencils

We bought 1 pack of paper at 3 dollars and p pencils at 2 dollars

15  = 1*3 + p*2

15 = 3+2p

Subtract 3 from each side

15-3 = 3+2p-3

12 = 2p

Divide by 2

12/2 = 2p/2

6 = p

Answer:

y = m x + b      standard form for straight line

m = (y2 - y1) / (x2 - x1)

When y2 = 12,  x = -6

when y = 0, x = -2

m = (12 - 0) / (-6 - (-2)) = -3

so y = -3 x + b

Also, when x = 0, y = -6

Our equation is

y = -3 x - 6

As a check try x = -2

y = (-3 * -2) +  (-6) = 0     as the graph shows
