Answer:
4 + 12 × 19 + 24
Step-by-step explanation:
Hullo!
Words like "added or sum", represent addition.
Words like "times", represent multiplication.
Words like "subtracted or took away", represent subtraction.
Words like "divided or split up", represent division.
Therefore, we can express the equation 4 added to 12 times 19 plus 24 can be rewritten as
in expression format.
Hope this helps!
Answer:
1st number: 20
2nd number: 25
3rd number: 75
Step-by-step explanation:
x + y + z = 120
x = y - 5
z = 3y
plug that in!
(y-5) + y + (3y) = 120
remove the parenthesis (I used them to show you what I was replacing), and add like terms.
5y - 5 = 120
move -5 to the other side
5y = 120 + 5
5y = 125
divide both sides by 5
y = 25
now that you have one number, use the equations from before to solve for the rest!
x = (25) - 5
z = 3(25)
_____________________________________________________
x = 20
y = 25
z = 75
