3x + ky = 8

sattari [20]

Answer:

(a): x is 3 and ky is -1

(b): k is -2

Step-by-step explanation:

Let: 3x + ky = 8 be equation (a)

x - 2 ky = 5 be equation (b)

Then multiply equation (a) by 2:

→ 6x + 2ky = 16, let it be equation (c)

Then equation (c) + equation (b):

${ \sf{(6 + 1)x + (2 - 2)ky = (16 + 5)}} \\ { \sf{7x = 21}} \\ { \sf{x = 3}}$

Then ky :

${ \sf{2ky = 3 - 5}} \\ { \sf{ky = - 1}}$

${ \bf{y = \frac{1}{2} }} \\ { \sf{ky = - 1}} \\ { \sf{k = - 2}}$

What is the length of side a? Round to the nearest tenth of an inch. Enter your answer in the box. ( Answer in Inches )

Jet001 [13]

Given:

Base of a right triangle = 7 in

Height of a right triangle = a

Hypotenuse = 16 in

To find:

The length of side a.

Solution:

Using Pythagoras theorem:

$\text{Base}^2+\text{Height}^2=\text{Hypotenuse}^2$

$7^{2}+a^{2}=16^{2}$

$49+a^{2}=256$

Subtract 49 from both sides.

$49+a^{2}-49=256-49$

$a^{2}=207$

Taking square root on both sides, we get

a = 14.4

The length of side a is 14.4 in.
