Answer:

Step-by-step explanation:

The sum of the angle measures of a triangle is 180°. Find the value of x . Then find the angle measures of the triangle.

find the value of x

x + 2x + x + 8 = 180

4x = 180 - 8

4x = 172

x = 172 : 4

x = 43

find angles

2x = 43 * 2

2x = 86°

-------

x = 43°

--------

x + 8 = 43 + 8

x = 51°

-----------------------

check

86 + 43 + 51 = 180°

the answer is good

CAN SOMEONE PLEASE EXPLAIN WHY THE ANSWER FOR THIS IS 4N+15. THIS IS 10 MINUTES PAST DUE!!! TAKE 20 POINTS​
Oduvanchick [21]
The first part of the expression 4n is because n is the amount of almond trees and to find the walnut trees, you need to multiply the number of almond trees (n) by for (4n). you would also add 15 because it says he has 15 more than 4 times as many walnut trees.

so here's the breakdown of the sentence:

Daquan has 15 more than (15 +) 4 times as many (4n) walnut trees in his orchard as he has almond trees.

hopefully this makes sense! have a nice day

Find the perimeter of the polygon
Zielflug [23.3K]

Answer:

100

Step-by-step explanation:

Okay so I'm not 100% sure but I think it's 100 because:

Angle B and D are the same, so the 12.5 areas will be the same (I honestly suck at explaining I'm really sorry.) But, if you add the sides from angle B and D it will be 50 because 12.5 + 12.5 + 12.5 + 12.5 (or 12.5 * 4). Meanwhile, For angle A and C, both outsides are the same as the other side.

I'm so sorry I can't explain the problem well but once you add them:

11.5 + 11.5 + 12.5 + 12.5 + 12.5 + 12.5 + 13.5 + 13.5 = 100

Tracy works at the Pizza Place. She earns $4.50 an hour plus tips. Last week, she earned a total
sweet [91]

Answer:

She work <u>23 hours</u>.

Step-by-step explanation:

Given:

Tracy works at the Pizza Place. She earns $4.50 an hour plus tips.

Last week, she earned a total  of $156.00, of which $52.50 was tips.

Now, to find the number of hours she work.

Total salary  = $156.00

Amount of tips = $52.50.

So, first we deduct the amount of tips from the total salary:

\$156.00-\$52.50\\=\$103.50.

<em>Thus, the remaining salary = $103.50.</em>

As, given salary she earns an hour = $4.50.

And then, to get the number of hours she work last week by dividing $103.50 the remaining salary by $4.50:

103.50\div 4.50

=23\ hours.

Therefore, she work 23 hours.

Is 3/5 and 1/10 closest to 0, 0.5, or 1
GaryK [48]
To determine the answer, we need to express the fractions into its decimal counterparts. 3/5 is equal to 0.6 therefore it is closest to 0.5 while 1/10 is equal to 0.1 therefore it is the last option. Hope this answers the question. Have a nice day.

Solve. 10x^2 = 6 + 9x10x 2 =6+9x10, x, start superscript, 2, end superscript, equals, 6, plus, 9, x Choose 1 answer: Choose 1 an
yulyashka [42]

Answer:

Option B.

Step-by-step explanation:

If a quadratic equation is defined as

ax^2+bx+c=0         .... (1)

then the quadratic formula is

x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}

The given equation is

10x^2=6+9x

It can rewritten as

10x^2-9x-6=0            .... (2)

On comparing (1) and (2) we get

a=10,b=-9,c=-6

Using quadratic formula we get

x=\dfrac{-(-9)\pm \sqrt{(-9)^2-4(10)(-6)}}{2(10)}

x=\dfrac{9\pm \sqrt{81+240}}{20}

x=\dfrac{9\pm \sqrt{321}}{20}

Therefore, the correct option is B.
