15. Solve for the specified variable: - х + 7 8 - 10; for y.

Andreyy89

Answer:

$y=80-\frac{8x}{7}$

Step-by-step explanation:

15). Given equation is,

$\frac{x}{7}+ \frac{y}{8}=10$

Multiply the equation by 8,

$8(\frac{x}{7}+ \frac{y}{8})=10\times 8$

$\frac{8x}{7}+y=80$

Subtract $\frac{8x}{7}$ from both the sides of the equation,

$\frac{8x}{7}+y-\frac{8x}{7}=80-\frac{8x}{7}$

$y=80-\frac{8x}{7}$

Therefore, value of the variable 'y' will be,

$y=80-\frac{8x}{7}$

Caroline wants to compare the expressions 15-9 and 9 (-15) to determine which result is greater. How can she do this without fin

Drupady [299]

Answer:

15-9 will be greater

Step-by-step explanation:

Caroline wants to compare the expressions 15-9 and 9 (-15)

For us to know the result that is greater, we will have to check if the first value is less than or greater than the other. For example

If for a-b

a-b is greater if a>b

a-b is lesser if a<b

Given 15 - 9

Since 15 > 9, this means that 15-9 will be greater compare to 9-15

Noel and Casey both start at the same place. Noel walks due south and Casey walks due east. After some time has passed, Noel is

Dovator [93]

Answer:

2.04 miles per hour

Step-by-step explanation:

Given

Noel

$n_1 =6miles$

$r_1 = 2mph$

Casey

$c_1 = 8miles$

$r_2 =1mph$

Required

The rate at which the distance increases

Their movement forms a right triangle and the distance between them is the hypotenuse.

At $n_1 =6miles$ and $c_1 = 8miles$

The distance between them is:

$d_1 = \sqrt{n_1^2 + c_1^2}$

$d_1 = \sqrt{6^2 + 8^2}$

$d_1 = \sqrt{100}$

$d_1 = 10miles$

After 1 hour, their new position is:

New = Old + Rate * Time

$n_2 = n_1 + r_1 * 1$

$n_2 = 6 + 2 * 1 = 8$

And:

$c_2 = c_1 + r_2 * 1$

$c_2 = 8 + 1 * 1 = 9$

So, the distance between them is now:

$d_2 = \sqrt{n_2^2 + c_2^2}$

$d_2 = \sqrt{8^2 + 9^2}$

$d_2 = \sqrt{145}$

$d_2 = 12.04$

The rate of change is:

$\triangle d = d_2 -d_1$

$\triangle d = 12.04 -10$

$\triangle d = 2.04$
