What is the distance between -70 and -30 on a number line

Lina20 [59]

Answer:

40 units

Step-by-step explanation:

On the number line, the distance between x and y is given by

|x-y|.

To find the distance between -70 and -30 on the number line, we find the absolute value of their difference.

$| - 30 - - 70| = | - 30 + 70| = |40| = 40$

Therefore the distance between -70 and -30 on the number line is 40 units.

Find the value of x! Justify your answer!

Daniel [21]

Answer:

Use the Triangle exterior angle theorem. The definition of this theorem, is that the exterior angle you are solving for is the sum of the two opposite interior angles. Set the equation:

80 + x = 3x - 22

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract x and add 22 to both sides.

80 (+22) + x (-x) = 3x (-x) - 22 (+22)

80 + 22 = 3x - x

Simplify.

102 = 2x

Isolate the variable, x. Divide 2 from both sides.

(102)/2 = (2x)/2

x = 102/2

x = 51

Check. Plug in 51 to the equation given.

80 + x = 3x - 22

80 + (51) = 3(51) - 22

131 = 153 - 22

131 = 131 (True).

The cost of a babysitting on a cruise is 10 for the first hour, and 12 for each additional hour. If the total cost of baby Aaron

Sliva [168]

Answer:

5 hours was Aaron at the sitter

Explanation:

Cost of baby sitting for the first hour: 10

Cost of baby sitting for additional hour= 12

Total cost of babysitting= 58

Since the cost of first hour is 10

Hence the remaining cost after first hour

= 54-10

=48

Which means 1 hour is consumed in the first hour

Now to calculate the remaining hours for every additional hour

= $\frac{48}{12}$

=4 hours

Hence the total hour Aaron was with the sitter

= 1 hour + 4 hours

= 5 hours
