There is no such word as quationbra and I feel like you either spelled it wrong or you got an unreal word.
X + z = 15
w + y = 10
(3w + 3y(2x + 2z) = 3(w + y) * 2(x + z) = 3*10 + 2*15 = 60 Answer
Answer:
The original number is 4
Step-by-step explanation:
Let x be the number.
5 is added to x => 5+x
When it is multiplied by 3,
3*(5+x) = 27
=> 15 + 3x = 27
Subtract 15,
3x = 27 - 15 = 12
Divide by 3,
x = 4
The lengths of AC is 24 and CB is 12
Explanation: so we know that the ratio is 2:1, which can be expressed as 2x and x.
we know that 2x+x must equal 36, so we can set up the equation 2x+x=36
we then add 2x to x to make 3x=36, divide both sides by 3, and get x=12.
now that we know what x equals, 2(12) is 24 and (12) is 12 :)
