Write down a common denominator for 7/8 and 9/10. Then compare the fractions when they have the common denominator.
X-0.075x=7400
Solve for x
0.925x=7400
x=7,400÷0.925
X=8,000
Answer:
B. 5 cm
Step-by-step explanation:
We are given that,
Length of the segment DE = 5 cm
Now, the transformation applied to DE is .
That is, the segment DE is,
<em>Rotated by 270° about the origin counter-clockwise and then reflected across x-axis.</em>
It is required to find the length of the segment which is the image of DE.
Since, we know,
The only transformation which changes the measurements of the figure is 'dilation'.
Thus, rotation and reflection will not change the shape and size of the segment DE.
Hence, the length of the image of DE will be same as that of DE i.e. 5 cm.
Answer:
x=3 or x=−9
Step-by-step explanation:
Step 1: Subtract 27 from both sides.
x2+6x−27=27−27
x2+6x−27=0
Step 2: Factor left side of equation.
(x−3)(x+9)=0
Step 3: Set factors equal to 0.
x−3=0 or x+9=0
x=3 or x=−9
Answer:
x=3 or x=−9
