Answer:
-10.4
Step-by-step explanation:
Assume that the number we are looking for is x.
Now, we want to get 10 times the sum of half the number and 6 and equate this expression to 8. Then we can solve for x
step by step
half the number is 0.5x
the sum of half the number and 6 is 0.5x + 6
10 times the sum of half the number and 6 is 10(0.5x +6)
10 times the sum of half the number and 6 equals 8 is 10(0.5x+6) = 8
Now solve for x
10(0.5x + 6) = 8
5x + 60 = 8
5x = 8 - 60
5x = -52
x = -52/5
x = -10.4
Answer: 126 milligrams
Step-by-step Easy to answer but all your doing is converting your mg's and 35% into decimals. and you will get your answer
Answer:
$2,950
Step-by-step explanation:
We can use the simple interest formula for this:
<em>P = initial balance</em>
<em>r = annual interest rate</em>
<em>t = time</em>
First, change 12% into its decimal form:
12% -> -> 0.12
Next, we need to change the annual interest rate to 1.5 since 18 months is 1.5 years. Now plug in the values:
The total amount owed after 18 months is $2,950
The slope intercept equation can be represented as follows:
y = 9 / 7 x + 1
y = 11 / 4 x - 8
y = 11 / 8 x + 6
<h3>How to write slope intercept equation?</h3>
The slope intercept equation can be represented as follows:
y = mx + b
where
Therefore,
The slope intercept equation can be represented as follows:
9x - 7y = - 7
7y = 9x + 7
y = 9 / 7 x + 1
11x - 4y = 32
4y = 11x - 32
y = 11 / 4 x - 8
11x - 8y = -48
8y = 11x + 48
y = 11 / 8 x + 6

For this, we will be using the pythagorean theorem, which is . Since we have the hypotenuse and one of the legs, we can solve for the other leg. Our equation will look like this:
Firstly, solve the exponents:
Next, subtract 3600 on both sides:
Next, square root both sides, and your answer will be x = 80 units
