Answer:

2/7

Step-by-step explanation:

I am assuming that you mean 285714 repeating.

You just have to memorize or learn to recognize the order of decimal digits for fractions over 7, unless you want to do it algebraically.

1/7=0.142857 repeated

2/7=0.285714 repeated and so on

Solve the equation for all values of x. ∣4x + 4 ∣- 10 = 3x

sertanlavr [38]

Answer:

X = 6 , – 2

Step-by-step explanation:

| 4x +4| - 10 =3x

4x +4 - 10 = 3x

4x - 3x = 10 - 4

x = 6

_____o___o____

– (4x + 4) – 10 = 3x

– 4x – 4 – 10 = 3x

3x + 4x = – 4 – 10

7x = – 14

x = – 14/ 7

x = – 2

£440 is divided between David, Mark & Henry so that David gets twice as much as Mark, and Mark gets three times as much as H

Lesechka [4]

Mark received £ 132

Solution:

Given that £440 is divided between David, Mark & Henry

Let "d" be the share of david

Let "m" be the share of mark

Let "h" be the share of henry

Total amount is 440

Therefore,

share of david + share of mark + share of henry = 440

d + m + h = 440 ------- eqn 1

David gets twice as much as Mark

d = 2m ----- eqn 2

Mark gets three times as much as Henry

m = 3h

$h = \frac{m}{3}$ ------ eqn 3

Substitute eqn 2 and eqn 3 in eqn 1

$2m + m + \frac{m}{3} = 440\\\\\frac{6m + 3m + m}{3} = 440\\\\10m = 1320\\\\m = 132$

Thus Mark received £ 132

Given h(x) = 5x + 2, solve for 2 when h(x) = -8.

san4es73 [151]

Answer:

$\huge\boxed{\sf x = -2}$

Step-by-step explanation:

$\sf h(x) = 5x+2\\\\Put \ h(x) = -8\\\\-8 = 5x+2\\\\Subtract \ 2 \ to \ both \ sides\\\\-8-2 = 5x\\\\-10 = 5x\\\\Divide\ both \ sides \ by \ 5\\\\-10 / 5 = x \\\\x = -2 \\\\\rule[225]{225}{2}$

Hope this helped!

What type of triangle has an exterior angle that is obtuse at two vertices? Explain your reasoning.

navik [9.2K]

Answer:

A right triangle

Step-by-step explanation:

A right triangle would meet these characteristics. A triangle's inner angles always add up to be 180 degrees. A right triangle has one angle at 90 degrees meaning the other two angles need to be less than 90 degrees and sum up to be 90 degrees. This would indicate that both of these angles' exterior angles would be obtuse because they would be wider than 90 degrees.
