Answer:
1 taco costs $1.5 and 1 burrito costs $3.25
Step-by-step explanation:
-Let t denote tacos and b denote burritos.
-The system of equations in the two weeks can then be expressed as below:
make t the subject of the formula in i and then substitute in ii to solve for both unknowns:
Hence, 1 taco costs $1.5 and 1 burrito costs $3.25
Answer:
B. x≥-3
Step-by-step explanation:
To solve this problem, first you have to isolate it one one side of the equation.
First, multiply -1 from both sides.
(-9x)(-1)≥27(-1)
Solve.
27*-1=-27
9x≥-27
Next, divide by 9 from both sides.
9x/9≥-27/9
Then, solve.
-27/9=-3
Therefore, the correct answer is x≥-3.
I = PRT
105 = 700 (.05)(T)
105 = 35T
105/35 = T
3 = T
