Answer:
The expression can be 1+1÷1×1-1 or 5×2+1-20÷2
Step-by-step explanation:
Consider the provided information.
The all four basic operation of mathematics are: +, -, ×, ÷
We need to use all the above operations to write an expression that has a value of 1.
There can be several ways to write an expression that has a value of 1.
Few of them are shown below:
1+1÷1×1-1=1
The another expression that has a value of 1 is:
5×2+1-20÷2=1
Hence, the expression can be 1+1÷1×1-1 or 5×2+1-20÷2
Answer:
The value of w is 5.
Step-by-step explanation:
To find the value of w, we start with the slope equation. Then, we input all of the values we are given.
m(slope) = (y2 - y1)/(x2 - x1)
-8 = (7 - -1)/(w - 6)
-8 = 8/(w - 6)
Now to solve for w, we need to cross multiply.
-8(w - 6) = 8
w - 6 = -1
w = 5
To find the value 'w', we use the equation for calculating the slope of a line given two points. After placing the known values into the equation, we solve for 'w' and find that w = 5.
To solve for w, we utilize the formula for the slope of a line given two points (x1, y1) and (x2, y2), which is (y2-y1)/(x2-x1). In our case, we know the slope is -8, and we have one point (6, -1) and another point (w, 7).
So, we set up the equation -8 = (7 - (-1)) / (w - 6). Simplifying this gives -8 = 8 / (w - 6). Cross multiply gives -8*(w - 6) = 8, which simplifies to -8w + 48 = 8. Subtracting 48 from both sides gives -8w = -40, so w = 5.
