Answer:
x = {-1/5, 1}
Step-by-step explanation:
(5x - 2)² - 1 = 8
Add 1 to both sides
(5x - 2)² = 9
Take the square root of both sides
5x - 2 = ±3
------------------------------
<u>Solution I</u> for 5x - 2 = +3
5x - 2 = 3
add 2 to both sides
5x = 5
Divide both sides by 5
x = 1
------------------------------
<u>Solution II</u> for 5x - 2 = -3
5x - 2 = -3
add 2 to both sides
5x = -1
Divide both sides by 5
x = -1/5
-------------------------------
x = {-1/5, 1}
Short Answer: B
Remark
The area of any triangle is
A = 1/2 b * h
b = 7 3/4
h = 4 2/3
Step one
Convert all fractions to improper fractions.
7 3/4 = (28 + 3) / 4 = 31/ 4
4 2/3 = (12 + 2) / 3 = 14/3 Now multiply
Step Two
Multiply
Area = 1/2 * 31/4 * 14/3 Multiply the numerators together and then the denominators.
Area = (1 * 31 * 14) / (2 * 4 * 3) = 434 /24
Step 3
Convert this to a whole number + a fraction
Area = 18 + 0.08333333 You already have your answer. It is B because only B gives an answer of 18. But you can get the rest of
Let x = 0.083333333
100 x = 8.3333333333
<u>x = 0.0833333333 </u> Subtract
99 x = 8.25 Divide by 3 on both sides.
33 x = 2.75 Divide by 11
3x = 0.25
x = 0.25/3 Multiply top and bottom by 4
x = 1 / 12
The answer is 18 1/12.
I got C but not sure if that is right
There are 20 nickels in 1 dollar so you would do 20 x 5 which is 100
So there are 100 nickels in 5 dollars :)
