X = 35
Step 1: Multiply both sides of the equation by seven thirds
Step 2: Reduce sides
Step 3: Multiply the numbers
Answer:
x = 16
Step-by-step explanation:
(x +4) : (x +12) :: (x-1)(x +5)
As they are in proportion,
Product of means = Product of extremes
(x + 4)* (x +5) = (x + 12)(x - 1) {Use FOIL method}
x*x +x*5 +4*x + 4*5 = x *x + x*(-1) +12*x + 12*(-1)
x² + <u>5x + 4x</u> + 20 = x² <u>- x +12x</u> - 12 {Now combine like terms}
x² + 9x + 20 = x² + 11x -12
x² + 9x +20 - x² - 11x = -12
x² - x² + 9x - 11x = -12 - 20
0 - 2x = - 32
-2x = -32 {Divide both sides by -2}
x = -32/-2
x = 16
Answer: 0%
Step-by-step explanation:
There are 5 colors of jelly beans.
Kaz ate all the green beans, so now only 80% of the jelly beans remain.
Kaz ate half of the orange pieces so now only 70% of the jelly beans remain.
Then Kaz ate half of the remaining pieces, so only 35% of the beans remain.
Current numbers: 0% green, 5% orange, 10% red, yellow, blue
Then he eats red and yellow candies in equal proportions until only 15% of the beans remain. This means that he ate 20% worth of red and yellow beans. This means that he ate all of the red and yellow beans.
Thus, there are 0% red beans left.
In order to get g(x) you would multiply the equation of f(x) by -1/2.
4x(-1/2)=-2x and -2(-1/2)=1.
Answer:
$861.09
Step-by-step explanation:
You are going to want to use the compound interest formula, which is shown below.
<em>A = total
</em>
<em>P = principal amount
</em>
<em>r = interest rate (decimal)
</em>
<em>t = time (years)
</em>
<em />
First, change 3.25% into its decimal form:
3.25% -> 
-> 0.0325
Next for <em>t, </em>we can use 4.25 since 4 years and 3 months is 4.25 in its decimal form. Now lets plug in the values:
Your answer is $861.09
