If you use metric conversion (shown below), you will find that 9 meters = 90 cm. Tell me if you need further explanation.
-108=8x
Divide 8 on both sides
-13.5=x
The answer is...X=-13.5

Answer:
W= -2
Step-by-step explanation:
Simply the expression: 9(w – 4) – 7w = 5(3w – 2)
First step: 9w -36-7w = 15w-10
Second step: 2w-36=15w-10
Third step:-36+10=15w-2w
Fourth step:-26=13w
Fifth step: w=
Six step: w=-2
Answer:
12/77
Step-by-step explanation:
-3/7 ÷ -11/4
switch the numerator and denominator around because of division
-3/7×-4/11=12/77
as negatives cancel each other out

Answer:
3. x = 10
4. a = 8
Step-by-step explanation:
A reasonably simple rule to remember for secants outside the circle or chords inside the circle: <em>the product of the lengths from the point of intersection of the lines to the points of intersection of the circle is the same for each line</em>.
When the external line is tangent to the circle, the two points of intersection of the line with the circle are the same: the point of tangency. Effectively, this means the length is squared.

3. For line QP, the product is 3(3+5) = 24.
For line QR, the product is 2(2+x). The rule above says these are equal:
24 = 2(2+x)
12 = 2+x . . . . . divide by 2
10 = x . . . . . . . subtract 2
__
4. For line BC, the product is (a)(a) = a^2.
For line GC, the product is 4(12+4) = 64. The rule above says these are equal:
a^2 = 64
a = √64 . . . . take the square root
a = 8
