Step-by-step explanation:
i d k if this is what ur looking for but hope this helped :)
<span>Melvina's age is = x, Bettina's age is = 3x
the equation is
x + 20 = 3x - 20
subtract 3x from both sides
-(3x) + x +20 = 3x - 20 - (3x)
-2x + 20 = -20
subtract 20 from both sides
-2x + 20 - (20) = -20 - (20)
-2x = - 40
divide both sides by -2
(-2x)/-2 = (-40)/-2
x = 20
Melvinas age is 20 and Bettinas age is 60</span>
Step-by-step explanation:
10% more = 110% of the number.
110% of the number = 132
100% of the number = 132 * (10/11) = 120.
The number is 120.
Answer:
if you are asking what the measure of the other angle is if it's just two angles and they are supplementary, the answer is 145º
Step-by-step explanation:
Supplementary angles would add up to equal 180º.
Angle W, which we already know is 35º.
Let's just call the other angle "x" for now.
1. Since we know the two angles will equal 180º, we can do x + 35= 180
2. Now we have the equation set up, and we can subtract 35 from each side
3. Once you subtract 35 from each side, you get x = 145º, which is your answer!
