8x - 2y-120 = 0 subsitute the x with zero to find the y intercept 0x - 2y-120=0 -2y-120=0 -2y=120 y=60 substitue the y with zero to find the x intercept 8x-120=0 8x=120 x=120/8 x=15 lol hopefully i did this rite... sorry if i didnt XD i have a coordinate geometry test tomorrow... lol
The four consecutive odd numbers which add up to 120 are 27, 29, 31 and 33. It can be found out as follows: Let 'x' be the smallest odd number. The next odd numbers will be 'x+2', 'x+4', 'x+6'. The addition of these four numbers will give 120. Therefore, x+(x+2)+(x+4)+(x+6)=120 4x+12=120 x+3=30 Therefore, x=27.
If 45 = 120% then simply divide 45 by 120, to find 1%, which is 0.375 and then multiply this by 80 to find 80%, which is 30 - or - 1.20X = 45; X = 45/1.20 = 37.5; then 80% of the number is: 37.5 X .80 = 30
The value for x is 13. 10 x 13 = 130. 3 x 13 = 39. 130 + 39 = 169.
Assuming you mean 3x-20=130 3x=150 x=50
