- Solving systems of equations by graphing
Step-by-step explanation:
Where the 2 lines intersect is the solution set to the systems of equations.
If the 2 lines are parallel, they have no solution.
If the 2 lines are the same, they have infinite amount of solutions.
Answer:
1 1/9 miles
Step-by-step explanation:
If john swims 5/12 of a mile in 3/8 of an hour, then;
5/12 miles = 3/8 hours
TO get the number of miles he swims in an hour, we will say;
x miles = 1 hour
Equating both expressions
5/12 miles = 3/8 hours
x miles = 1 hour
Cross multiply
3/8 x = 5/12
3x/8 = 5/12
3x * 12 = 5 * 8
36x = 40
x = 40/36
x = 10/9
x = 1 1/9
The amount he swims in an hour is 1 1/9 miles
The amount that Cocoa cups normally charge for a cupcake is $2.50.
The principal was given a discount for each cupcake. The discount costs $0.60. This means that the cost of each cupcake cost was reduced by $0.60.
In order to determine the normal charge for a cupcake, the first step is to determine the discounted cost for one cupcake.
Discounted cost for one cupcake = total discounted cost for for 50 cupcakes / 50
$95 / 50 = $1.90
The normal price for one cupcake can be determined using this formula:
normal price = discounted price + discount given
$1.90 + $0.60 = $2.50

Answer:
The answer is zero or cannot be solved
Step-by-step explanation:
According to the question given,we will have to deal with the bracket first
7+(5+b)=(5+b)+7
7+5+b=5+b+7
12+b=12+b
There is no way to solve this question further because any further solution will definitely give us zero
