Answer:

x=16/5, y=13/5

Step-by-step explanation:

  1. Multiply by 4 on the first equation and get a new equation: 4x-8y=-8
  2. Plus the new and second equation: 4x-8y+(-4x+3y)=-8+(-5), and got -5y=-13, so y=13/5
  3. After getting y=13/5, substitute in the first equation, x-2*(13/5)=-5, and got x=16/5

Sin10°-cos10° product and evaluate​
Montano1993 [528]

Question should be sin 20 cos 10 + cos 20 sin 10

remember sin (a+b) = sin a cos b + cos a sin b ?

sin 20 cos 10 + cos 20 sin 10

= sin (20+10)

= sin 30

= 1/2

Answer:

7 -if rounded to the nearest tenth would be 10

Step-by-step explanation:

The median is the number in the middle so

6-6-7-7-10-12-14

There are 7 numbers here so the middle number is 4 because there are 3 numbers before 4 and 3 numbers after 3 to get to 7 (that’s really hard to explain sorry but it’s a simple concept) my trick is to write it down then use two fingers to point at the first and last number and keep doing that moving in til I get to the middle number, which is 7. :)
