solve the variables for x,y,z ​

Answer:

8 yrs

Step-by-step explanation:

3(5+x)=31+x

15+3x=31+x

2x=16

x=2

Answer:

8 years.

Step-by-step explanation:

let after x years father's age is 3 times that of Rahul.

31+x=3(5+x)

31+x=15+3x

31-15=3x-x

2x=16

x=16/2=8

Hey this is me again ....

[tex] \frac{210}{60} = \frac{x}{90} \\ [/tex]

[tex] \frac{21}{6} = \frac{x}{90} \\ [/tex]

Multiply both sides by 90

[tex]90 \times \frac{21}{6} = 90 \times \frac{x}{90} \\ [/tex]

[tex]15 \times 21 = x[/tex]

[tex]x = 315[/tex]

So that shop would sell 315 donuts in 90 minutes

Holy crab that is too much donuts impressive....

Answer:

3.2 brainliets

Step-by-step explanation:

Step-by-step explanation:

f(x) = ³√x -15

y = ³√x - 15

Finding inverse,

x = ³√y - 15

x³ = y -15

y = x³ + 15

f-¹(x) = x³ + 15

Answer:

14x+3=8x+3

14x+3 -3 = 8x+3 -3

Cancels out the 3

14x = 8x

14x - 8x = 8x -8x

Cancels out the 8x

14x = 0

x = 0

Step-by-step explanation:

Andre should have collected the like terms in order to have all the variables x on one side before taking the difference.

Given the inequality expression solved by andre expressed as:

14x + 3 ≤ 8x + 3

Simplify to have:

14x - 8x ≤ 3-3

6x ≤ 0

x ≤ 0

Hence andre should have collected the like terms in order to have all the variables x on one side before taking the difference.

Answer:

a. 3.4m

b. 12.2m

Step-by-step explanation:

SOH CAH TOA

[tex]Sin QPS=\frac{Opposite}{hypotenuse}[/tex]

sin 15° = [tex]\frac{QS}{PQ}[/tex]

QS= sin 15° * PQ

QS = 0.2588 * 12.6 = 3.36088 ≈ 3.4m

a. The length of QS = 3.4m

b. [tex]cos QPS=\frac{Adjacent}{Hypotenuse}[/tex]

Cos 15° = [tex]\frac{PS}{PQ}[/tex]

PS = Cos 15° * PQ

PS = O.9659 * 12.6 = 12. 17034 ≈ 12.2m

The length of PS = 12.2m

Answer:

A and B

Step-by-step explanation:

times 2 both sides

7x+6<=6x+4

minus 6x both sides

x+6<=4

minus 6 both sides

x<=-2

becuase x is less or equal than -2 it must be x=-3 and x=-2

Answer:

Step-by-step explanation:

0056 because 1% is 72 so you know it’s going to have to be less then 72. So to get your percent you divide 40 by 7200 so 40/7200. This will get you .00555556 which I rounded to .0056

Answer:

0.91

Step-by-step explanation:

Answer:

0.913

Step-by-step explanation:

Answer:

He pays $8.00 regardless and $1.40 for each ride. When we see for each, we typically want to multiply.

A. $8.00 + $1.40 * r

If his parents gave him $26.00, then that is the most Kolby can spend.

$8 + $1.40 * r = $26

Subtracting 8 from both sides:

$1.40 * r = $18

Dividing both sides by 1.40:

r = 12.86

B. Since you can't ride part of a ride, Kolby can only ride 12 rides.

Step-by-step explanation:

Answer:

An expression to represent this would be 1.40x+8.00= R

1.40x+8=26

       -8   -8

1.40x=18

/1.40    /1.40

x=11 total rides

If you had $26.00 you would first spend $8.00 on the entry leaving you with $18.00. Then you would divide the $18 by $1.40 for each ride to get 12.8... It doesn't make sense to go on a fraction of a ride so you just round down to 11 rides

Step-by-step explanation:

Answer:

Step-by-step explanation:

(f*g)(x) = (-5x² + 2x + 7) (x +1)

          = x* (-5x² + 2x + 7) + 1*(-5x² + 2x + 7)

          = x*(-5x²) + x*2x + x*7 - 5x² + 2x + 7

        = -5x³ + 2x² + 7x - 5x² + 2x + 7

        = - 5x³ + 2x² -5x²   + 7x + 2x +7   {Combine like terms}

       =  -5x³ - 3x² + 9x + 7

4) (f*g)(x) = (x² + 2x + 4)(x - 2)

                = x*(x² + 2x + 4) - 2*(x² + 2x + 4)

                = x*x² + x*2x + x*4 - 2*x² - 2*2x -2* 4

                = x³ + 2x² + 4x  -2x² -4x - 8

                = x³ - 8
