Solve:-
x + 67 = 83
Inverse operation.
83 - 67 = x
83 - 67 = 16
x = 16
Check:-
x + 67 = 83
x = 16
16 + 67 = ?
16 + 67 = 83
Correct!
x = 16
Y=6x
Since she uses 6 beads per inch, you would just multiply 6 by the number of inches (x)
The point (-4, 7) is in the 2nd quadrant. The coordinate of the preimage
of a -90 degrees rotation that resulted to point (-4, 7) will be in the
third quadrant. (i.e. both x and y is negative). Hence, answer is (-7,
-4).
Answer:
5 and 12 inches
Step-by-step explanation:
Let the shorter leg be x.
13²=x²+(x+7)²
169=x²+x²+14x+49
169=2x²+14x+49
120=2x²+14x
120=2x(x+7)
60=x(x+7)
60=x²+7x
x=5
shorter length=5, longer length=12
