Question

Roberto wrote a sentence that describes an equation. Half of a number is 45. Which choice shows Roberto’s equation and its solution? 2 x = 45; x = 90 StartFraction 45 Over 2 EndFraction = x; x = 22. 5 StartFraction x Over 2 EndFraction = 45; x = 22. 5 StartFraction x Over 2 EndFraction = 45; x = 90.

Answer 1

Your answer is [tex}x = 45 * 2x = 90[/tex]

x = 45 * 2

x = 90

90 : 2 = 45

Hope this helps

Sorry if the thing says alot of "tex". Trying something new

Answer 2

x = 90

Explanation:

Roberto wrote a sentence that describes an equation. Half of a number is 45. Which choice shows Roberto’s equation and its solution? 2 x = 45; x = 90 StartFraction 45 Over 2 EndFraction = x; x = 22. 5 StartFraction x Over 2 EndFraction = 45; x = 22. 5 StartFraction x Over 2 EndFraction = 45; x = 90.

(1/2)x = 45

x = 45 * 2

x = 90

--------------------

check

90 : 2 = 45

the answer is good
