Find x-intercept and y-intercept of the line given the equation 8x-2y-120?
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
Find four consecutive odd numbers which add up to 120?
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.
45 is 120 percent of a number what is 80 percent of the same number?
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
If 10x plus 3x 169 what is x?
The value for x is 13. 10 x 13 = 130. 3 x 13 = 39. 130 + 39 = 169.
What is the value of x if 3x - 20 130?
Assuming you mean 3x-20=130 3x=150 x=50
