Izaiaih would only be spending $309.75 since it was 35% off
Answer:
1/3
Step-by-step explanation:
Probability of solving ten problems by Carl
Given
Total number of problems = 20
Number of problems studied by Carl = 15
Number of problems out of the 20 set of problem coming in test is 10
Case I - All ten problems come from the set of known 15 question
10/15 * 10/20 = 1/3
Let us suppose a system of two equations with two unknowns.
Suppose further that the system of equations is linearly independent.
When the system of equations has a variable that has exactly the same coefficient in both equations, then the most effective method to solve the system of equations is subtracting.
This is because we eliminate one of the variables and reduce the system to an equation with one unknown.
Answer:
a system of equations in which subtraction would be the most efficient way of solving the system is:
A system of equations in which one of the variables has exactly the same coefficient in both equations.
0.12b+0.40=19
This is your answer i hope I helped you :)
If I am thinking right I think that the answer would be the third opption
