Answer:

-93.5

Step-by-step explanation:

let the number be y

1/2 × y + 49 =2 1/4

y/2 +49 =9/4

y/2 =9/4-49

y/2 = 9-196/4

y/2 = -187/4

cross multiply

4y = -374

y = -93.5

Answer:

  • 28

Step-by-step explanation:

<u>Let the number is x</u>

  • Half of a number = (1/2) x
  • 2 whole 1/4 of the number = (2 1/4) x = (9/4) x

<u>The sum:</u>

  • (1/2) x + 49 = (9/4) x
  • (9/4)x - (1/2)x = 49
  • (9/4 - 1/2)x = 49
  • (7/4)x = 49
  • x = 49 : 7/4
  • x = 49 * 4/7
  • x = 7 * 4
  • x = 28

How many solutions does 2.3y+3.2-y=2.1+1.3y+1.1 have?
jeka57 [31]
1.3y +3.2 = 1.3y +3.2

we notice that both sides of the equation are identical. So substitute y with any value and the equation would still be correct.

y has infinite solutions.
