Answer 1

can you type out the equations in the triangle?

Answer 2

Hi there!

A triangles angles will always add up to 180°.

Therefore, we can add these equations to get 180° and then find x.

(4x-2) + (7x-2) + (5x-8) = 180°

Now we simply the equation by combining like terms.

16x -12 = 180°

Now we can solve for x. ^w^

16x -12 = 180°
+12 +12
~~~~~~~~~~~~~
16x = 192
/16 /16
~~~~~~~~~~~~~
x = 12

Yay! We found x. Now we plug it into each equation:

~ 4x-2
4(12)-2
48-2
46°

~ 7x-2
7(12)-2
84-2
82°

~ 5x-8
5(12)-8
60-8
52°

It’s always a good idea to check if these angles add up properly to 180°.

46° + 82° + 52° = 180°

Congrats! We are all done ^u^

Answers:

X = 12
mx = 46°
my = 82°
mz = 52°

Find the slope of each line

Answers

Rise over run

5 up over 4 left

-5/4 is your slope

Answer: The slope is -5/4.

Step-by-step explanation: The slope of a line refers to its direction and steepness. The slope can be expressed as a fraction that is commonly refered to as rise over run. In order to find the slope of a line, you need to find two coordinates on the line and use the "rise over run" method. The numerator (rise) is how many units up or down while the denominator (run) is how many units left or right. There are two given points on this specific line. To get from one to the other, you must go down 5 units and to the right 4 units; therefore, the slope, or rise over run, is -5/4.

What is the median length of the wingspans?

50 millimeters

54 millimeters

55 millimeters

57 millimeters

Answers

Answer:

The median is the middle of your data when it is arranged in order.

Since you have 9 data points, the median will be the 5th value.

Your data in numerical order would be:

50 50 52 53 54 55 55 55 57

Therefore, the median is 54mm

Step-by-step explanation:

Answer:

B. 54

Step-by-step explanation:

Put all numbers from least to greatest in order and cross one out on each side until you reach the final number in the middle with even crosses on each side.

50, 50, 52, 53, 54, 55, 55, 55, 57

50- crossed

57- crossed

50- crossed

55- crossed

52- crossed

55- crossed

53- crossed

55- crossed

Which leaves 54! Hope this helps, good luck! :)

i think the answer is 13,840

to start off use the formula IPRT which stands for interest, principal, rate, and time. so then you do 2,000 times 6% (or 0.06) then times that by 18 which is 2,160 so she earned 2,160 in her college account, next you add the 1,000 and that would make it 3,160. next you subtract 3,160 from 17000 to see how much she still has to pay which i think is 13,840

A hamburger costs 30¢ more than a hot dog and 20¢ less than a cheeseburger. If 3
hamburgers cost 75¢ less than 2 hot dogs and 2 cheeseburgers, how much does a
hamburger cost?

Answers

Let h be the price of a hamburger, d be the price of a hot dog and c be the price of a cheeseburger
3+d=h —(1)
c-20=h —(2)
3h=2d+2c-75 —(3)

Sub (1), (2) into (3)
3h=2(h-3) + 2(h+20) -75
3h =2h-6+2h+40-75
3h=4h-41
h=41

Therefore, the price of a hamburger is $41

The price of the hamburger is 41
