Answer:

w = 4

Step-by-step explanation:

Rewrite the equation as 14w - 7w = 28

Now subtract 7w from 14w

7w = 28

Divide

7w/7 = 28/7

28/7 = 4 > w = 4

The hypotenuse of a right triangle is 10cm long. One of the triangle's legs is three times the length of the other leg. Find the

vivado [14]

Answer:

The lengths of the three sides are 10 cm, 9.49 cm and 3.16 cm

Step-by-step explanation:

Let

c ------> the length of the hypotenuse of a right triangle

x -----> the length of one leg

y -----> the length of the other leg

we know that

$c^{2}=x^{2}+y^{2}$ -----> equation A (Pythagoras Theorem)

$c=10\ cm$ ----> equation B

$x=3y$ -----> equation C

Substitute equation B and equation C in equation A and solve for y

$10^{2}=(3y)^{2}+y^{2}$

$100=10y^{2}$

$y^{2}=10$

$y=\sqrt{10}\ cm$

$y=3.16\ cm$

Find the value of x

$x=3(\sqrt{10})=9.49\ cm$

therefore

The lengths of the three sides are 10 cm, 9.49 cm and 3.16 cm

Solving 2- Step Equations with Like Terms and Distribute Property: How do you solve this?

larisa86 [58]

Hi there! The answer is y = -2

$- 25 = 7y - 3 + 4y$

First we collect terms.
$- 25 = 11y - 3$

Now we add 3 to both sides of the equation.
$- 22 = 11y$

Finally we divide both sides by 11.
$y = - 22 \div 11 = - 2$

Hence, the answer is y = - 2

Ethan is thinking of a negative number that is lower than -4 and higher than

s2008m [1.1K]

When the number is odd and a multiple of 3, the number that Ethan is thinking of is -9.

<h3>How to illustrate the number?</h3>

In mathematics, a multiple is the product of any quantity and an integer. It should be noted that, for the quantities a and b, it can be said that b is a multiple of a if b = na for some integer n, which is called the multiplier. If a is not zero, this is equivalent to saying that b/a is an integer.

In this case, Ethan is thinking of a negative number that is lower than -4 and higher than -10 and his number is odd and a multiple of 3. The number is -9 since 9 is a multiple of 3.

Find the perimeter of the triangle defined by the coordinates (9, 0), (-5, 0), and (-10, 6). (Round to nearest tenth)

Masteriza [31]

The perimeter is 41.7

Find the length of each side using the distance formula:
$d=\sqrt{(0-0)^2+(-5-9)^2}=\sqrt{0^2+14^2}=\sqrt{196}=14
\\
\\d=\sqrt{(6-0)^2+(-10--5)^2}=\sqrt{6^2+(-5)^2}=\sqrt{36+25}=\sqrt{61}=7.8
\\
\\d=\sqrt{(6-0)^2+(-10-9)^2}=\sqrt{6^2+(-19)^2}=\sqrt{36+361}=\sqrt{397}=
\\19.9$

Adding the side lengths, we have
14+7.8+19.9=41.7
