Answer:

SUM OF ALL ANGLES ÓF A TRIANGLE=180

THEREFORE,

4X+7X-2+5X-10=180

16X-12=180

16X=192

X=12

THEREFORE,

<A=4X=4*12=48

<B=7X-2=7*12-2=84-2=82

<C=5X-10=5*12-10=60-10=50

Answer:

...

Step-by-step explanation:

7x - 2 +5x - 10 +4x = 180

16x - 12 = 180

16x = 168

x = 10.5

now plug it in

7(10.5) - 2 = 71.5°

4(10.5) = 42°

5(10.5) -10 = 42.5°

What is the mean median mode and range of the numbers 31 28 30 31 30 ...?
mamaluj [8]
1. Mean is the number you get when you add all these numbers and then divide by the number of numbers. So, (31 + 28 + 30 + 31 + 30) / 5 = 150 / 5 = 30
2. The median is the middle number in the list of numbers, so, the answer is 30 as well.
3. Mode is the number that appears most often, so here it is 30 and 31 because they both appear 2 times.
4. Range is the difference between the largest and smallest number, so 31 - 28 = 3.

M= 1 1/2 going through (6,4) plug into y=mx=+b
Tema [17]
M = 1.5 = 3/2
y = mx + b
b = y - mx = 4 - (3/2)6 = 4 - 9 = -5
So equation of the line is:
y = 3x/2 - 5

Whats 3.2r + 14.7=6.74
Nata [24]

<u><em>r=-199/80 is the right answer.</em></u> First, you had to multiply by 100 from both sides of the equation. And it gave us, 3.2r*100+14.7*100=6.74*100. Next, you had to refine, and it gave us, 320r+1470=674. Then, subtract by 1470 from both sides of equation. And it gave us, 320r+1470-1470=674-1470. Simplify, and it gave us, 320r=-796. You can also divide by 320 from both sides of equation. And it gave us, \frac{320r}{320}=\frac{-796}{320}. And finally, simplify, and it gave us the answer is <em><u>r=-199/80 is the right answer.</u></em> Hope this helps! And thank you for posting your question at here on brainly. And have a great day! -Charlie
