Answer:
(x+3) x+7 is the answer for the first question if it's the same way my school does it. Whatever you put in parentheses is the opposite of what you think. + is going to the left. - is going to the right but those only apply when in parentheses.
Answer:
4.8 liters
Step-by-step explanation:
o=orange juice c=cranberry juice
Punch = 4/5o + 1/6c it means that any quantity of punch will have the same proportion of the two ingredients
now, you know that 1 liter can be written as 6/6 liters, so to get those 6/6 you multiply 1/6 by 6
for the proportion to remain valid, you must multiply by 6 also the other ingredient so (4/5)*6 = 24/5 of a liter of orange juice per liter of cranberry juice and 24/5 = 4.8 liters
A-1538=1074
a=1538+1074
a=2612
b+718=1074
b=1074-718
b=356
2000-c=1074
c=2000-1074
c=926
2612-356+926=3182
Answer:
84 is the highest possible course average
Step-by-step explanation:
Total number of examinations = 5
Average = sum of scores in each examination/total number of examinations
Let the score for the last examination be x.
Average = (66+78+94+83+x)/5 = y
5y = 321+x
x = 5y -321
If y = 6, x = 5×6 -321 =-291.the student cannot score -291
If y = 80, x = 5×80 -321 =79.he can still score higher
If If y = 84, x = 5×84 -321 =99.This would be the highest possible course average after the last examination.
If y= 100
The average cannot be 100 as student cannot score 179(maximum score is 100)
