Answer:12
Step-by-step explanation:
Your goal with variables should always be to isolate them.
so the first step is to subtract the 4
3x^2+4=436
-4= -4
3x^2=432
The next step to isolate the variable x is to get rid of the 3. To get rid of the 3 you have to divide both sides by 3 since it is the opposite of multiplying.
3x^2=432
/3. =/3
x^2=144
the last step to isolate the x is to do the opposite of what an exponent is, which is to find the square root. So when you square the x^2, the exponent cancels out.
square root of x^2=x
square root of 144=12
x=12
hope this helps!
Given that <span>Lisa had 1,750 stamps and Mark had 480 fewer stamps than Lisa.</span>
Thus, the number of stamps Mark had is 1,750 - 480 = 1,270
Given that <span>Lisa gave some stamps to Mark which makes Mark to have three times as many stamps as Lisa.</span>
Let the number of stamps that Lisa gave to Mark be x, then
![3(1,750 - x) = 1,270 + x \\ \\ \Rightarrow5,250-3x=1,270+x \\ \\ \Rightarrow x+3x=5,250-1,270 \\ \\ \Rightarrow 4x=3,980 \\ \\ \Rightarrow x= \frac{3.980}{4} =995](https://tex.z-dn.net/?f=3%281%2C750%20-%20x%29%20%3D%201%2C270%20%2B%20x%20%5C%5C%20%20%5C%5C%20%5CRightarrow5%2C250-3x%3D1%2C270%2Bx%20%5C%5C%20%20%5C%5C%20%5CRightarrow%20x%2B3x%3D5%2C250-1%2C270%20%5C%5C%20%20%5C%5C%20%5CRightarrow%204x%3D3%2C980%20%5C%5C%20%20%5C%5C%20%5CRightarrow%20x%3D%20%5Cfrac%7B3.980%7D%7B4%7D%20%3D995)
Thus, Lisa gave Mark 995 stamps.
Therefore, the number of stamps that Lisa have now is 1,750 - 995 = 755.
