Answer:
x = 7, x = 5
Step-by-step explanation:
Given 2 intersecting chords, then
The product of the parts of one chord is equal to the product of the parts of the other chord.
(1)
27x = 9 × 21 = 189 ( divide both sides by 27 )
x = 7
(2)
12(3x - 5) = 120 ( divide both sides by 12 )
3x - 5 = 10 ( add 5 to both sides )
3x = 15 ( divide both sides by 3 )
x = 5
1. a+3a+4b=5b
2. a+3a=5b-4b
3. 4a=5b-4b
4. 4a=b
a=1/4b
(I think 1/4b is the answer) hope this helps :)
Answer:
= 3.5 * 3.5 = 12
square means: multiply the number <u>by itself</u> two times. so 3.5 * 3.5
cube (
) means: multiply the number by itself three times. so 3.5 * 3.5 * 3.5
i hope u understand :)
A+c = 150
10.25a+7.75c = 1470
