Solve 3(x − 4) = 12x
x=?

Answer:

18

Step-by-step explanation:

plug 4 for z

3(4)+6=18

answer: $1,080

explanation: interest = principal x rate x time

>> interest = 6,000 x 0.06 x 3

after multiplying, you get 1,080, which is the simple interest

**tip: turn the rate/percent into a decimal, then multiply

Step-by-step explanation:

Answer:

raise 3^4 and ans is 81 or u can simply multiply.

The value of e is 0.1 in the equation 10e=1.

In the equation 10e = 1, the letter "e" represents an unknown variable.

To find the value of "e," you need to isolate it on one side of the equation.

Divide both sides of the equation by 10:

(10e) / 10 = 1 / 10

This simplifies to:

e = 1/10

e=0.1

Hence, the value of e is 0.1.

Answer:

[tex]t^2+1[/tex]

Step-by-step explanation:

We are given that

Distance traveled by a toy car

[tex]D(t)=t^3-3t^2+t-3[/tex]

Where t>3

Time taken by car =t-3 seconds

We have to find the expression which represents the speed of the toy car.

We know that

[tex]Speed=\frac{Distance}{time}[/tex]

Using the formula

[tex]Speed=\frac{(t^3-3t^2+t-3)}{t-3}[/tex]

[tex]Speed=\frac{t^2(t-3)+(t-3)}{t-3}[/tex]

[tex]Speed=\frac{(t-3)(t^2+1)}{t-3}[/tex]

[tex]Speed=t^2+1[/tex]

Hence, the expression  which represents the speed of the toy car

[tex]t^2+1[/tex]

The expression  that represents the speed of the toy car is [tex]t^2 + 1[/tex].

Given that,

The distance traveled should be [tex]D(t) = t^3 - 3t^2 + t - 3[/tex]

Here t>3

Time taken by car = t -3 seconds

Now the expression should be

[tex]Speed = Distance \div time\\\\= ( t^3 - 3t^2 + t - 3) \div (t - 3)\\\\= t^2(t - 3) + (t - 3) \div (t - 3)\\\\= (t - 3) (t^2 + 1) \div (t - 3)\\\\= t^2 + 1[/tex]

Answer:

The equation to represent the situation is [tex]10 = \frac{k}{4}[/tex]

Step-by-step explanation:

It is given that:

Amount of gas left in tank varies inversely with the amount of the time.

Let,

g represents the gas

t represents the time

g ∝ 1/t

[tex]g = \frac{k}{t}[/tex]

Here, k represents the constant of proportionality.

Putting g = 10 and t = 4 in the equation

[tex]10 = \frac{k}{4}[/tex]

Therefore,

The equation to represent the situation is [tex]10 = \frac{k}{4}[/tex]

Answer:

Conclusion:

As y = -3 MAKES the inequality TRUE.

Therefore, option D i.e. y = -3 is true.

Step-by-step explanation:

Given the inequality

3y² + 2(y - 5) > 8

For y = 0

substitute y = 0 in the inequality

3y² + 2(y - 5) > 8

3(0)² + 2(0 - 5) > 8

3(0) + 2(-5) > 8

0 - 10 > 8

-10 > 8

FALSE!

-10 can not be greater than 8.

Hence, y = 0 does not make the inequality true.

For y = -1

substitute y = -1 in the inequality

3y² + 2(y - 5) > 8

3(-1)² + 2(-1 - 5) > 8

3(1) + 2(-6) > 8

3 - 12 > 8

-9 > 8

FALSE!

-9 can not be greater than 8.

Hence, y = 1 does not make the inequality true.

For y = -2

substitute y = -2 in the inequality

3y² + 2(y - 5) > 8

3(-2)² + 2(-2 - 5) > 8

3(4) + 2(-7) > 8

12 - 14 > 8

-2 > 8

FALSE!

-2 can not be greater than 8.

Hence, y = -2 does not make the inequality true.

For y = -3

substitute y = -3 in the inequality

3y² + 2(y - 5) > 8

3(-3)² + 2(-3 - 5) > 8

3(9) + 2(-8) > 8

27 - 16 > 8

11 > 8

TRUE!

11 is indeed greater than 8.

Hence, y = -3 MAKES the inequality TRUE.

Conclusion:

As y = -3 MAKES the inequality TRUE.

Therefore, option D i.e. y = -3 is true.

Given :  tan 235 = 2 tan 20 + tan 215

To Find : prove that

Solution:

tan 235 = 2 tan 20 + tan 215

Tan x = Tan (180 + x)

tan 235 = tan ( 180 + 55) = tan55

tan 215 = tan (180 + 35) = tan 35

=> tan 55 = 2tan 20 + tan 35

55 = 20 + 35

=> 20  = 55 - 35

taking Tan both sides

=> Tan 20 = Tan ( 55 - 35)

=> Tan 20  = (Tan55 - Tan35) /(1 + Tan55 . Tan35)

Tan35 = Cot55 = 1/tan55 => Tan55 . Tan35 =1

=> Tan 20  = (Tan 55 - Tan 35) /(1 + 1)

=> Tan 20  = (Tan 55 - Tan 35) /2

=> 2 Tan 20  = Tan 55 - Tan 35

=> 2 Tan 20 +  Tan 35 = Tan 55

=>  tan 55 = 2tan 20 + tan 35

=>  tan 235 = 2tan 20 + tan 215
