Yes because 2.4 in half is 1.2

Answer:

Judy's claim to divide 2.4 by 2 is the same as multiplying 2.4 * 0.5 is:

  • <u>Correct</u>.

Step-by-step explanation:

Multiplying a number by 0.5 (whose fractional is 1/2) is the same as dividing this number by 2, this case is very easy to identify by making different examples in which said decimals and integers are used, checking that the result is the same:

EXAMPLES.

1. 12*0.5 = 6

   12/2 = 6

2. 3*0.5 = 1.5

   3/2 = 1.5

3. 5.5*0.5 = 2.75

   5.5/2 = 2.75

As you can see in the previous examples, performing the operation by both methods is correct.

I am trying to understand how to solve for X, then solve the equation
Alina [70]

Answer:

x = 16

m<Y = 34°

Step-by-step explanation:

∆XYZ is an isosceles ∆. An isosceles ∆ has two equal sides, as well as the bases of the isosceles triangle are congruent. In this case, therefore:

<X = <Z

(6x - 23)° = (4x + 9)

Solve for x

6x - 23 = 4x + 9

Collect like terms

6x - 4x = 23 + 9

2x = 32

Divide both sides by 2

x = 16

m<Y = 180° - (m<X + m<Z) (sum of ∆)

m<Y = 180 - ((6x - 23) + (4x + 9))

Plug in the value of x

m<Y = 180 - ((6(16) - 23) + (4(16) + 9))

m<Y = 180 - (73 + 73)

m<Y = 34°

What is the range of the function shown in the graph below? answer type: interval, all real values except one, all real values e
Sever21 [200]

Answer:

Hey there!

The range is the possible y values, so the range of this graph would be all real numbers less than or equal to -6.

Let me know if this helps :)
