Answer:

x=12

Step-by-step explanation:

you have to group the like terms in order to solve this equation, this will result to;

5/2x-3/4x=14+7

1.75x/1.75=21/1.75

x=12

I hope this helps

Required solution :

The given equation is,

⇒ 5x - 14 / 2 = (3 / 4)x + 14

Transposing 14 from R.H.S. to L.H.S.,

⇒ (5x - 14 / 2) - 14 = (3/4)x

⇒ 5x - 14 - 28 / 2 = 3x / 4

⇒ 5x - 42 / 2 = 3x / 4

⇒ 4 (5x - 42) / 2 = 3x

⇒ 4 × (5x - 42) / 2 = 3x

⇒ 2 (5x - 42) = 3x

⇒ 10x - 84 = 3x

⇒ 10x - 3x = 84

⇒ 7x = 84

⇒ x = 84 / 7

⇒ x = 12

Therefore, option d that is 12 is correct.

Answer:

$121.81

Step-by-step explanation:

A=  4000(1+.03/365)^365

[tex]4000\left(1+\frac{0.03}{365}\right)^{365}=4121.81305\dots[/tex]

Total interest earned on Sandra’s card after 1 year is $4,121.81

Compound interest is defined as interest paid on the original principal and the interest earned on the interest of the principal.

A=P(1+r/n[tex])^{nt}[/tex]

Where:

A = the future value of the investment or loan

P = the principal investment or loan amount

r = the interest rate (decimal)

n = the number of compound periods

Given,

A=P(1+r/n[tex])^{nt}[/tex]

Sandra makes a credit card purchase for $4,000 that compounds interest daily.

P = $4,000

r =3%

t = 1 year

A=P(1+r/n[tex])^{nt}[/tex]

Substitute the values of P, r and t in the formula,

First, convert R as a percent to r as a decimal

r = R/100

r = 3/100

r = 0.03 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 4,000.00(1 + 0.03/365)(365)(1)

A = 4,000.00(1 + 8.2191780821918E-5)(365)

A = $4,121.81

Therefore, total interest earned on Sandra’s card after 1 year is $4,121.81.

Answer:

Step-by-step explanation:

Start by finding the radius

d = 8

r = d/2

r = 8/2

r = 4

Next find the height

the height = 3 times the radius

the height = 3 * 4

The height = 12

Volume = pi * r*r * h

pi = 3.14

r = 4

h = 12

V = 3.14 * 4 * 4 * 12

V = 602.88

Answer:

t(10) = 15

Step-by-step explanation:

5 - (-3)/ 5 - 1

= 2

t(n) = t1 + (n - 1)(d)

t(10) = -3 + (10 - 1)(2)

t(10) = -3 + (9)(2)

t(10) = -3 + 18

t(10) = 15

Answer:

x=7

Step-by-step explanation:

3/2x + 7/2 = 2x

Subtract 3/2x from each side

3/2x -3/2x + 7/2 = 2x-3/2x

7/2 = 2x -3/2x

Get a common denominator

7/2 = 4/2x - 3/2x

7/2 = 1/2 x

Multiply each side by 2

7/2 *2 = 1/2x*2

Answer:

y int: The starting value. Domain: All Real Numbers. Range: y<=30,000. The Function is decreasing

Step-by-step explanation:

The y int. is the starting value because it is the point where no years have started yet on the x axis so that means that the value of the car will be as if you had just bought it. The domain is all real numbers because the number of years you could have the car could be infinate. The range is the y axis part meaning that it could be any number starting from 30,000 and decreasing because the car value is constantly decreasing. And due to the fact that the price is going down every year by 15%, the function is decreasing.

The number of kilowatt-hours used KWH is 471.6 KWH.

Since the power bill for the month says you pay 15 cents per kilowatt-hour, this is the rate of the bill. We convert this a a dollar rate.

So, 15 cents per kilowatt-hour = 15 cents × $ 1/100 cents per kilowatt-hour (since $ 1 = 100 cents)

= 15 cents/100 × $ 1/100 cents per kilowatt-hour

= 0.15 × $ 1/100 cents per kilowatt-hour

= $ 0.15 cents per kilowatt-hour.

Since the power bill came out to be $ 70.74, we need to find the number of kilowatt-hours used KWH.

The total amount on bill = rate of bill × number of kilowatt-hours used.

So, number of kilowatt-hours used = total amount on bill/rate of bill

Total amount on bill = $ 70.74 and rate of bill =  $ 0.15 cents per kilowatt-hour.

So, number of kilowatt-hours used = total amount on bill/rate of bill

number of kilowatt-hours used = $ 70.74 /$ 0.15 cents per kilowatt-hour.

number of kilowatt-hours used = 471.6 KWH

So, number of kilowatt-hours used KWH is 471.6 KWH.

Answer:

x = 5

Step-by-step explanation:

B, bisects AB. So, AB = BC

AC = AB  +BC

     = AB + AB

AC = 2AB

[tex]\dfrac{1}{2}AC = AB\\\\AB = \dfrac{1}{2}AC\\\\2x + 10 =\dfrac{1}{2}*40\\\\2x + 10 = 20[/tex]

Subtract 10 from both sides,

2x = 20 - 10

2x = 10

Divide both sides by 2

x = 10/2

x = 5

The sum that represents the number of tickets sold if 35 tickets were sold Monday, half of the remaining tickets were sold on Tuesday and 14 tickets were sold on Wednesday.

To start solving this, we can assign t as the variable to the total number of tickets that were sold. So, t = 35 (for Monday) + (t - 35)/2 (for Tuesday) + 14 (for Wednesday). To solve this, we can say t = 49 + (t - 35)/2, or 2t = 98 + t - 35, which equals t = 63. Therefore, 63 tickets were sold total.

Initial velocity (u) = 0m/s

Final velocity (v) = 20m/s

Time (t) = 10 s

Acceleration (a)

= (v - u)/t

= [(20m/s) - (0m/s)]/10s

= (20m/s)/10s

= (20m/s²)/10

=> 2m/s²
