Answer:
q=
−4t+7u over 8r
Step-by-step explanation:
8qr+4t=7u
Step 1: Add -4t to both sides.
8qr+4t+−4t=7u+−4t
8qr=−4t+7u
Step 2: Divide both sides by 8r.
8qr
8r
=
−4t+7u
8r
q=
−4t+7u
8r
Answer:
q=
−4t+7u
8r
Answer is Correct. She could have also subtracted 100 from both sides, then divided by .
Answer:
8 cm
Step-by-step explanation:
the 3 cm line from the chord to the center of a circle is a leg of a right triangle which perpendicularly bisects the chord into two equal halves
draw the hypotenuse of the right triangle from the center of the circle to the endpoint of the chord. This is a radius measuring 5 cm.
find the missing leg of the right triangle
a^2= c^2- b^2
a^2= 25-9
a^2=16
a=4
this is only the measurement of half the chord. To find the full length of the chord multiply by two
4*2=8 cm
Answer:
There is 5 numbers (not including the sum/25)
The average is add up all the numbers and divide by amount of numbers
25/5=5
The average value is 5
