Please help me with this -2 - (-0.7)

Mathematics
1 answer:
Amanda [17]3 years ago

Anytime you subtract a negative number, it changes it to adding a positive number.

-2 + 0.7

Since we are adding, we will have an arrow going to the right

-2 + 0.7 = -1.3

Therefore, we will have a point starting at -2, an arrow pointing to the right and stopping at -1.3

Best of Luck!

The variable z is inversely proportional to x when x is 3 z has the value 1.6666666666667. What is the value of z when x =12 ??
Harlamova29_29 [7]

The governing equation is z = k/x.

When x=3, z = 1 2/3, or z = 5/3. Find k: 5/3 = k/3. Then k = 5, and the

governing equation becomes z = 5/x.

Now if x=12,

z = 5/12 (answer)

Answer: The number of the adult tickets is 168

Step-by-step explanation: * Lets explain how to solve the problem

- The adults ticket costs $10.50

- The students ticket costs $3.75

- The total money of the opening night is $2071.50

- The equation of the total money earned in the opening night is:

10.50 a + 3.75 b = 2071.50, where a is the number of the adult ticket

 and b is the number of the student ticket

- There were 82 students attended

* Lets solve the problem

∵ 10.50 a + 3.75 b = 2071.50

∵ The number of the students attended is 82

∵ b is the number of the students

∴ b = 82

- Substitute the value of b in the equation

∴ 10.50 a + 3.75(82) = 2071.50

∴ 10.50 a + 307.5 = 2071.50

- Subtract 307.5 from both sides

∴ 10.50 a = 1764

- Divide both sides by 10.50

∴ a = 168

∵ a is the number of the adult tickets

∴ The number of the adult tickets is 168
