Help please guys I need help

Mathematics
1 answer:
omeli [17]3 years ago
7 0

Answer:

= 3 + 6/15 + 10/15

Step-by-step explanation:

To make 2/5 into a fifteenth, you have to multiply the 5 by 3 to get 15. Whatever you do to the top you have to do to the bottom, meaning that you have to multiply 2 by 3 to get 6 on top.

To make 2/3 into a fifteenth, you have to multiply the 3 by 5 to get 15. Whatever you do to the top you have to do to the bottom, meaning that you have to multiply 2 by 5 to get 10 on top.

This is the same rule for all equations involving fractions.

The absolute value of an integer is the distance from zero. So, another way of thinking of is to ignore positive or negative. for example the absolute value of -126 is 126, same would go for positive 126.

Consider the function below. (If an answer does not exist, enter DNE.) g(x) = 190 + 8x3 + x4 (a) Find the interval of increase.
galben [10]

Answer:

The interval of increase of g(x) is (-6,+\infty).

Step-by-step explanation:

The interval of increase occurs when first derivative of given function brings positive values. Let be g(x) = 190 + 8 \cdot x^{3} + x^{4}, the first derivative of the function is:

g'(x) = 24 \cdot x ^{2} + 4\cdot x^{3}

g'(x) = 4 \cdot x^{2}\cdot (6+x)

The following condition must be met to define the interval of increase:

4\cdot x^{2} \cdot (x+6) > 0

The first term is always position due to the quadratic form, the second one is a first order polynomial and it is known that positive value is a product of two positive or negative values. Then, the second form must satisfy this:

x + 6 > 0

The solution to this inequation is:

x > - 6

Now, the solution to this expression in interval notation is: (-6,+\infty)

What is the solution to the equation 2/3a-1/6=1/3
Vsevolod [243]

Answer:

a = \frac{3}{4}

Step-by-step explanation:

\frac{2a}{3} -\frac{1}{6} =\frac{1}{3}

\frac{4a}{6}-\frac{1}{6}  =\frac{2}{6}

(now you can multiply the whole equation by 6 to remove the fractions

4a - 1 = 2

4a = 2+1

4a = 3

a = \frac{3}{4}

A shop sells 3 types of boots football boots rugby boots and hiking boots sales are usually sold in the ratio 6:2:3 last moth 24
salantis [7]

Answer:

44

Step-by-step explanation:

The sum of the ratios is 6 + 2 + 3 = 11

Let b = total number of boots sold last week

If 24 football boots are sold, the equation representing this =

6/11 x b = 24

To solve for b, divide both sides by 11/6

b = 44 =  total number of boots sold last week
