A certain positive number is multiplied by 4, and then the result is subtracted from the original number. The result is 21 less
stira [4]

Answer:

The number is 7

Step-by-step explanation:

certain positive number: x

x is multipled by 4:

4x

result of this is subtracted from the original number:

so original number minus 4x,

x - 4x

the result is 21 less than 0, this means negative 21

x - 4x = 0 - 21 = -21

do algebra:

-3x = -21

multiply both sides by -1

3x = 21

divide both sides by 3

x=7

(certain positive number: x) is equal to 7

Solve 8(m - 5 ) = 48
Art [367]

Answer

1)8(m -5 ) = 48 \\ 8m - 40 = 48 \\ 8m = 48 + 40 \\ 8m = 88 \\  \frac{8m}{8}  =  \frac{88}{8}  \\ m = 11

2)x + 7 = 13 \\ x = 13 - 7 \\ x = 6

3)3h - 5 = 12 \\ 3h = 12 + 5 \\ 3h = 17 \\  \frac{3h}{3}  =  \frac{17}{3}  \\ h = 5 \frac{2}{3}

Hope this helps you.

Let me know if you have any other questions :-):-)

Let x1 = 12, y1 = 15, and y2 = 3. Let y vary inversely with x. Find x2.
Ostrovityanka [42]
We have that an inverse variation in a function is given by:
 y = k / x

 We must find the value of the constant k.
 To do this, we substitute the values of x1 = 12, y1 = 15.
 We have then:
 15 = k / 12

 Clearing k we have:
 k = (15) * (12)

k = 180
 Substituting the value of k we have that the inverse variation is:
 y = 180 / x

 For y2 = 3 we have:
 3 = 180 / x2

 Clearing x2 we have:
 x2 = 180/3
 x2 = 60
 Answer:
 
x2 = 60
