Answer:
Step-by-step explanation:
(distribute)
-3x -9 -3x + 3 + 8x = 4
(simplify)
2x -6 = 4
x=5
Answer:
DE = 21
Step-by-step explanation:
Recall: the ratio of the corresponding side lengths of similar triangles are equal
Given that ∆ABC ~ ∆DEF, therefore,
AB/DE = BC/EF = AC/DF
AB = 8.4
DE = x
BC = 10
EF = 25
AC = 16.5
DF = 41.25
Let's find DE using AB/DE = BC/EF. Thus:
8.4/x = 10/25
Cross multiply
x*10 = 25*8.4
10x = 210
Divide both sides by 10
x = 210/10
x = 21
DE = x = 21
Answer:
338 (1 Year)
365.58 (3 Years)
427.68 (7 Years)
712.12 (20 Years)
Step-by-step explanation:
To find the compounded annual value, we use the formula:
Let's first take each variable and list them:
P = 325
r = 4% or 0.04
t = 1, 3, 7, 20
n = 1
Let's take each number of years one at a time.
After 1 Year
After 3 Years
After 7 Years
After 20 years
-1,0,1/2,1.7
If you put 1/2 =0.5
THE ANSWER IS 2 IN SORRY ITS HARD GOR YIU YOULL GET BETTER AT IT
