Answer:
Step-by-step explanation:
1/2x - 2/3 × 15 = 30
1/2x - 10 = 30
1/2x = 30 + 10
1/2x = 40
x = 40 × 2
x = 80
hope this helps

Answer:
The radius of the inflated spherical balloon is 45 millimeters.
Step-by-step explanation:
Volume of the spherical water balloon = 121,500 pi cubic millimeters
Let the radius of the balloon = r
Now, Volume of a Sphere = 
⇒
On solving for the value of r, we get:
![r^{3} = \frac{121,500\times 3}{4} = 91125\\ \implies r = \sqrt[3]{91125}](https://tex.z-dn.net/?f=r%5E%7B3%7D%20%20%3D%20%5Cfrac%7B121%2C500%5Ctimes%203%7D%7B4%7D%20%20%20%3D%2091125%5C%5C%20%5Cimplies%20%20r%20%20%3D%20%5Csqrt%5B3%5D%7B91125%7D)
or, r = 45 millimeter
Hence, the radius of the inflated spherical balloon is 45 millimeters.
Try the lowest option first. 8 is not divisible by 3 so you can rule out D. The next lowest option is 24. 24 is divisible by all 4 numbers so that it is the answer.
ANSWER: A) 24
The values of the coefficient are ax^2+bx+c=
48x^2-24x+84 and A= 48, B=-24, C=84.
(4x-2)•6(2x+7)=
6•2x+ 6•7
(4x-2)(12x+42)=
4x•12x= 48x^2 4x•42= 168.
-2•12x= -24x -2•42=-84
48x^2-24x+168-84=
48x^2-24x+84=
A= 48, B=-24, C=84
ax^2+bx+c= 48x^2-24x+84.
