2. x + y = 82 x - y = 24 ---------------add 2x = 106 x = 53 x + y = 82 53 + y = 82 y = 82 - 53 y = 29 solution is : (53,29) ======================= 3. y = 2x y = 4x + 6 2x = 4x + 6 2x - 4x = 6 -2x = 6 x = -3 y = 2x y = 2(-3) y = -6 solution is (-3,-6) ======================== 4. 5x + 8y = -29 7x - 2y = -67...multiply by 4 ---------------- 5x + 8y = -29 28x - 8y = - 268 ..result of multiplying by 4 -----------------add 33x = - 297 x = - 9 5x + 8y = -29 5(-9) + 8y = -29 -45 + 8y = -29 8y = -29 + 45 8y = 16 y = 2 solution is : (-9,2) ======================= 5. y = -4x + 6 y = -5x - 4 -4x + 6 = -5x - 4 -4x + 5x = -4 - 6 x = -10 y = -4x + 6 y = -4(-10) + 6 y = 40 + 6 y = 46 solution is (-10,46) ========================= 6. H(m) = 2m + 12 H(m) = 3m + 10 ========================= 7. -8x + 4y > -52 4y > 8x - 52 y > 2x - 13 <== ========================= 8. 3x - y = 28 3x + y = 14 ---------------add 6x = 42 x = 7 3x - y = 28 3(7) - y = 28 21 - y = 28 -y = 28 - 21 -y = 7 y = -7 solution is (7,-7) ===================== 10. 5x - 5y > 70 -5y > -5x + 70 y < x - 14 <== ===================== 11. sorry...dont know ===================== 12. y = 4x + 4 y = -3x - 3 4x + 4 = -3x - 3 4x + 3x = -3 - 4 7x = -7 x = -1 y = 4x + 4 y = 4(-1) + 4 y = 0 solution is (-1,0) ======================= 13. -12x - 2y > - 42 -2y > 12x - 42 y < -6x + 21 <== ======================= 14. -5x + 2y = 9 3x + 5y = 7 solution is (-1,2) ======================== 15. 3x + 6y = -2 15x + 30y = -10....divide by 5 to reduce = 3x + 6y = -2 is the same line....infinite solutions ======================== 1. (the graph).....y < = 3x - 4....3rd one ======================== 9. (2nd graph)....y < = -3x + 4....last one

Answer:
70%
Step-by-step explanation:
I'm sorry but I don't really know how to explain it other than 70% of 30 is 21 so that means that 30% of the students turned their essay in on time.
(sorry for not being able to explain it but I hope it helped)
Clare has berries (b). Rasheed has 6 times more berries that Clare has, and Rasheed also has _ amount of watermelons. How much fruits does Rasheed have in all?
Answer:
2/5 or 40%
Step-by-step explanation:
.40 is 40 hundredths or 40/100
40/100 can be reduced to 20/50 and reduced again to 10/25 and one more time to 2/5
Percentages are fractions out of 100 so 40/100 would be 40%.
