Answer:
A single cheeseburger order cost $1.23
A single fries order cost $1.28
Step-by-step explanation:
Let the cost of cheeseburgers be c and the cost of fries be f
Mathematically;
4c + 3f = 10.75 ••••(i)
Secondly;
5c + 2f = 11.2 ••••(ii)
We have two equations to solve simultaneously;
Multiply i by 2 and ii by 3
8c + 6f = 21.5
15c + 6f = 33.6
Subtract ii from i
-7c = -12.1
c = 1.73
Recall;
5c + 2f = 11.2
5(1.73) + 2f = 11.2
2f = 11.2-8.65
2f = 2.55
f = 2.55/2
f = 1.28
Step-by-step explanation:
2x²+3x-2=0
(2x-1)(x+2)
x+2=0
x=-2 (no, because x must be >0)
2x-1=0
2x=1
x=½ (yes, because x>0)
Answer:
x=15
Step-by-step explanation:
The given equation is
Here the variable is x and the terms with the variable are
Keep all the terms having variable on one side and all the constants terms on the other side as
Now, simplify the above equation to get the value of x as
In this way, the value of x is 15.
