3x-y=13
2x + 2y = -10
change 2x + 2y = -10 into slope intercept form, making the equation y = -x -5. insert y = -x - 5 into 3x - y = 13, making the new equation 3x + x - 5 = 13. Add alike terms together (3x + x = 4x) then add 5 to both sides, making the new equation 4x = 18. divide both sides by 4, making x = 6. Insert 6 back into the old equation of y = - x - 5, making the old equation y = - 6 - 5. Add alike terms (- 6 - 5 = - 11) making y = -11 and x = 6. (6, -11) would be the ordered pair.
Answer:
Because it is a regular polygon, the sum of all exterior angles is equal to 360 degrees (one revolution). If each side has an exterior angle of 40 degrees, we simply divide 360 by 40 to get 9.
Step-by-step explanation:
Answer:
cp = rs 400
loss = 10%
Then SP = 400 - 10% of 400
= 400 - 40
= 360
Therefore SP = Rs. 360
Answer:
216 cub root is 6
Step-by-step explanation:
nce 216 can be expressed as 2 × 2 × 2 × 3 × 3 × 3. Therefore, the cube root of 216 = ∛(2 × 2 × 2 × 3 × 3 × 3) = 6.
