MATH HELP PLEASE! ( please show all work)

Mathematics
1 answer:
natita [175]2 years ago
6 0

Answer:

Step-by-step explanation:

Sin(42) = n/21

n = 21 * sin(42)

n = 21 *  0.6691

n = 14.052

Cos(42) = m / 21

21 * cos(42) = m

m = 21 * 0.7431

m = 15,61

Theta + 42 = 90

Theta = 90 - 42

Theta = 48

The sum of two numbers is eighteen. The total of three times the smaller and twice the larger is forty-four. Find the two number
sashaice [31]

Answer:

  • The numbers are 8 and 10.

Step-by-step explanation:

Let the numbers be x and y.

The sum of two numbers is eighteen:

  • x + y = 18

The total of three times the smaller and twice the larger is forty-four:

  • 3x + 2y = 44

Solve the system by substitution:

  • x = 18 - y

Substitute x and solve for y:

  • 3(18 - y) + 2y = 44
  • 54- 3y + 2y = 44
  • 54 - y = 44
  • y = 54 - 44
  • y = 10

Find x:

  • x = 18 - 10
  • x = 8

Can someone help me with this problem pls
GREYUIT [131]

Answer:

my answer was 7.5

Step-by-step explanation:

    2

2b+3b-10

4b+3b-10

10-7b=3b fraction bar means divide so...

3b

__                       2

4b because... b-2b=4b and 8-4b=4b

3/4 =7.5 because 4 cant go into three so you add a decimal and a zero and move decimal up and 4 can go into 30 7 time which equals 28 and 30-28 is 2 add another zero and its 20 and 4 goes in 5 times which equals 20 and 20-20=0 so its 7.5 (i hope this helps ;)
