Solve the absolute value equation |x| − 2 = 5 to find the distance Mary can walk forward, x, in 5 seconds.
Alisiya [41]

Answer:

x = 7 m and x = −7 m

Step-by-step explanation:

Its a modulus problem

concept

|x|  = x when x>=0

|x| = -x when x < 0

____________________________________

Now given

|x| − 2 = 5

adding 2 both sides

|x| − 2  + 2 = 5 + 2

|x|  = 7

now

x = 7  when x >= 0

x = -7 when x<0

Thus, correct answer is x = 7 m and x = −7 m

An artist is creating a sculpture where a globe with a diameter of 48 inches sits in a cone like a scoop of ice cream. She wants
brilliants [131]

Answer:

115.2 inches

Step-by-step explanation:

What we must do is calculate the ratio between the real version and the version to be imitated, in this case the ice cream cone.

To calculate the ratio, we will do it through the diameter:

48 / 2.5 = 19.2

So the ratio is 19.2: 1

Which means that one inch of the ice cream cone represents 19.2 inches in the real version.

Therefore, in the case of height it would be:

6 * 19.2 = 115.2

Therefore, the height should be 115.2 inches.

-30=5(x+1)−30=5(x+1) proszę szybką odpowiedź :)
den301095 [7]

Answer:

x = -7

Step-by-step explanation:

The given equation is :

-30=5(x+1)

We need to solve the equation.

Use associative property on RHS.

-30 = 5x+5

Subtract 5 from both the sides.

-30-5 = 5x+5-5

-35 = 5x

x = -7

Hence, the value of x is -7.
