Answer:
16.32
Step-by-step explanation:
8.32x-55.04=80
Add 55.04 on each side:
80+55.04=135.04
8.32x=135.04
Divide 8.32:
x=(Estimated) 16.32
Answer:
No, the radicands are not added.
Step-by-step explanation:
When adding or subtracting like radicals, we treat them as we treat algebraic expressions:
4 x + x - 2 x= 3 x
In the sense that we associate the "x" above with the radical expression. So for example:
![4\,\sqrt[3]{x-7} \,+\,\sqrt[3]{x-7} -\,2\,\sqrt[3]{x-7} = (4+1-2)\,\sqrt[3]{x-7} =3\,\sqrt[3]{x-7}](https://tex.z-dn.net/?f=4%5C%2C%5Csqrt%5B3%5D%7Bx-7%7D%20%5C%2C%2B%5C%2C%5Csqrt%5B3%5D%7Bx-7%7D%20-%5C%2C2%5C%2C%5Csqrt%5B3%5D%7Bx-7%7D%20%3D%20%284%2B1-2%29%5C%2C%5Csqrt%5B3%5D%7Bx-7%7D%20%3D3%5C%2C%5Csqrt%5B3%5D%7Bx-7%7D)
The radicals remain the same, and we treat them as algebraic expressions, just combining adequately the multiplicative factors the radicals have.
The example is 1 x (9 x 5) = 45
Using the associative property of multiplication, we basically rearrange the parenthesis to group the first two terms like so: (1 x 9) x 5
So this is why choice D (1 x 9) x 5 = 45 is the answer
This means that 1 x (9x 5) = (1 x 9) x 5 is a true equation
S would also increase if t is being increased
Since there are four suits, with each having a 4 and 5, we have 2+2+2+2=2*4=8
