Answer:
the x value is 41
x=77
y=62
z=41
Step-by-step explanation:
part 1:
2y-5+y+21+y=180
4y+17=180
4y=164
y=41
part 2:
w-2(41)-5=77
x-41+21=62
y-41
Answer:
<em>The actual distance between the cities is 1,200 Km</em>
Step-by-step explanation:
<u>Scaling
</u>
Objects can be represented in a reduced or augmented size by using scaling which is multiplying or dividing real dimensions by a constant factor. We use scaling when representing geographic locations on a map.
We are given the scale on a map as 1:20,000,000.
Two cities are 6 cm on the map. The actual distance is obtained by multiplying:
6 * 20,000,000 = 120,000,000 cm
Divide by 100 to convert to meters and by 1,000 to convert to km 120,000,000/100/1,000=1,200 Km
The actual distance between the cities is 1,200 Km
Each ticket is $34 each
32+12+2x=112
44+2x=112
-44 -44
———————-
2x=68

2 2
x=$34
2.8 ! the two is the whole and the fraction is the 8 after the decimal ! happy learning!

Subtracting numbers is one of the basic operations in math.
Firstly, the order of operations is as follows: PEMDAS or parentheses, exponents, multiplication, division, addition, then subtraction.
All of these are done in the exact order given above.
For example, given the equation (4 x 7) + (6 / 2) - 3^2 = ?
1. Parentheses
- Solve the equations within the parentheses first.
(4 x 7) + (6 / 2) - 3^2 = 28 + 3 - 3^2
2. Exponents
- Second, if there are any exponents, solve this.
28 + 3 - 3^2 = 28 + 3 - 9
3. Mulltiplication
4. Division
5. Addition
28 + 3 - 9 = 31 - 9
6. Subtraction
31 - 9 = 22
Answer: 22.
