2. A
3. B
Step-by-step explanation:
Answer:
B. +29 + +18
Step-by-step explanation:
+18- -29 what you do is you make the minus signs addition because when you are subtracting a negative it becomes a positive.
+29 + +18 is your answer.
Part A:
We see that this pair of equations has 1 solution. On a graph, the solutions of 2 (or more) lines is where the lines intersect. In this case, since these lines intersect 1 time, they have 1 solution.
Part B:
As previously mentioned, the solutions of multiple lines is where the lines intersect. In this case, since they intersect at (4,4), that is the solution.
Teresa's restaurant bill is 29.99 dollars before the tax.The sales tax is said to be 6.25% of the total amount .=> 6.25% = 0.0625=> 29.99 dollars * 0.0625 = 1.87 dollars is the sales tax that will be added to his payment,=> 29.99 + 1.87 = 31.86 dollars is now here current payment.Next, he needs to give 20% tip to the water.=> 31.86 * .20 = 6.37 dollars is the total amount for the tip to the waiter. => 31.86 + 6.37 = 38.23 dollars will be the total amount that Teresa needs to pay for her restaurant meal.<span>

Answer:
90°
Step-by-step explanation:
The sum of the arcs around the circle is ...
2x +4x +4x +2x = 360°
x = 360°/12 = 30°
The numbered angle is the average of the measures of the intercepted arcs, so is ...
(4x +2x)/2 = 3x = 3(30°) = 90°
The numbered angle is 90°.
