Answer:
C
Step-by-step explanation:
I didn't use your formula bc I do not understand it =). I just did 975 divided by 780. When you do this you will get 125. This means that 975 is 125% of 780. So it has to be 25% more than 780. You can see that 780 divided by 4 (25 times 4 is 100 so 25 % is one fourth) is 195. Then 780 plus 195 is 975.
Hope this helped you!

im sorry im not sure but i think 9
Step-by-step explanation:
t + c = 32
0.80 t + 0.40 c = 18
Multiplying the first by 0.8
0.8 t + 0.8 c = 0.8 (32) = 25.6
Subtracting,
0.8 c - 0.40 c = 25.6 - 18
0.40 c = 7.6
c = 7.6/.4 = 19
Answer: 19 cans of corn
Check
t = 32-19 = 13
.8(13)+.4(19) = 18 good
Answer:
Step-by-step explanation:
Slope of line through (5,4) and (3,7) = (7-4)/(3-5) = -1.5
Point-slope equation of line:
y-4 = -1.5(x-5)
Convert equation to standard form:
y-4 = -1.5x + 7.5
1.5x + y = 11.5
3x +2y = 23
