Answer:
Dana has 20 French fries.
They can purchase 5 bottles.
Step-by-step explanation:
1.
Let x rep. the amount of French fries Johnathan has.
Let 2x rep. the amount of French fries Abdullah has.
Let 10x rep. the amount of french fries Dana has.
If :
x+2x+10x=26
13x=26
x=2
So Johnny boy has 2 french fries which means Dana has 10 times as much as that.
10(x)=10(2)
10x=20
Therefore Dana has 20 French fries.
2.
Well
5.12+2.77+4=$11.89
11.89/1.99= APPROX. 5.9
Note you can't buy a fraction of a bottle. We gotta round down for this question cause you can't just give less amount of cash to get an extra bottle even if it's very close. Unless your teacher said to round something.
Therefore they can only purchase 5 bottles.

I think this is correct :)
Answer:
x is equal to 2.5 and -4.5
Step-by-step explanation:
-4(x + 1)² - 3 = -51
-4(x² + 2x + 1) - 3 = -51
-4x² - 8x -3 - 3 = -51
-4x² - 8x - 6 = -51
-4x² - 8x = -45
-4(x^2 + 2x) = -45
-4(x^2 + 2x + 1) = -49
-4(x + 1)² = -49
(x + 1)² = 49/4
x + 1 = ± √(49/4)
x + 1 = ± 7/2
x = -1 ± 3.5
x = 2.5, -4.5
Answer: imagine not knowing the answer
Step-by-step explanation:
Answer:
Step-by-step explanation:
x = y - 2.........(1)
4x + y = 2......(2)
Substituting x in (1) in (2)
4(y - 2) + y = 2
4y - 8 + y = 2
5y = 2 + 8
5y = 10
y = 10/5
y = 2
Putting x in (1)
x = y - 2
x = 2 - 2
x = 0
