Suppose that an Individual has a body fat percentage of 18.8% and weighs 127 pounds. How many pounds of her weight is made up of

Phoenix [80]

Answer:

14.8 pounds

Step-by-step explanation:

Here, we want to get the actual value made of fat from the body weight

What we have to do here is to multiply the percentage by the body weight

Mathematically, we have this as;

18.8% of 127 pounds

= 18.8/100 * 127 = 14.80 pounds

Solve for x please help

34kurt

Answer:

x = 9

Step-by-step explanation:

By remote exterior angle theorem:

$(12x + 14)\degree = (1 + 5x) \degree+ 76 \degree \\ 12x + 14 = 1 + 5x + 76 \\ 12x - 5x = 77 - 14 \\ 7x = 63 \\x = \frac{63}{7} \\ \huge \red{ \boxed{ x = 9}}$

Determine the value (or values) of h such that the matrix: 2 - 3 h - 6 9 5 is the augmented matrix of a consistent linear system

Verizon [17]

Answer:

In order to have a consistent linear system represented by the augmented matrix:

$\left[\begin{array}{ccc}2&-3&h\\-6&9&5\end{array}\right]$

the value of h must be:

$h=-\frac{5}{3}$

Step-by-step explanation:

A system is consistent if it has a solution, this solution can be unique or a set of infinite solutions.

First, you take the augmented matrix and find the equivalent row echelon form using Gaussian-Jordan elimination:

To do this, you have to multiply the 1st row by 3 and add it to the 2nd row, the resulting matrix is:

$\left[\begin{array}{ccc}2&-3&h\\0&0&5+3h\end{array}\right]$

Now, write the system of equations:

$2x_1-3x_2=h\\0x_1+0x_2=5+3h$

The only way this system has a solution is if 5+3h=0, then, to satisfy this, the value of h must be:

$h=-\frac{5}{3}$
