Answer:
Step-by-step explanation:
The main goal in any equation is to get the unknown variable all by itself. In this case that means moving the fraction of 7/8 over to the other side of the equals sign. On the left, the fraction is being subtracted; that means that to move it to the other side, we add it since adding is the opposite of subtracting.
On the left side, if you have 7/8 and then take that 7/8 away, it's gone completely. What we have now is
We need a common denominator so we can add 4 (which is 4/1) to 7/8. 8 is the common denominator.
and
giving us
I attached the answer right here the one on top is my answer the bottom is work

Step-by-step explanation:
The answer you are saying is correct if it was an equation
In inequalities the answer most of the times comes in ranges
The easiest way to find the range is by graphing the equation and finding the values of x for which the graph is above the x axis
There is a good graphing calculator app called desmos if u don't have one
Answer:
A is 3/1, B is 242/1 C is 36/1 D is 101/1
Step-by-step explanation:
We will calculate it like this, We will make a right angle triangle by adding one new point called O for example, and O is located right under the point C, and on the right side of point D, so the coordinated for this point are O (8, -2). From there, length CD is calculated using the Pythagorean theorem, because we know that the CO = 4 and DO = 4, so:
CD^2 = CO^2 + DO^2
CD^2 = 4^2 + 4^2
DC^2 = 16 + 16
DC^2 = 32
DC = square root of 32 = square root of 16 * square root of 2
DC = 4 * square root of 2
The correct answer is B. 4*square root of 2.
