Answer:
57 mph
Step-by-step explanation:
just devide 342 by 6
Answer:
26
Step-by-step explanation:
Since x is counted in hundreds, x=600/100.
x=6
6x-10
When you substitue,
6*6-10
36-10
26
you get 26.
Answer:
22. Perimeter = 52 units
Area = 160 Square Units
23. Notation form : ![2 \times 10^{5}](https://tex.z-dn.net/?f=%202%20%5Ctimes%2010%5E%7B5%7D)
Standard Form : 200000
Step-by-step explanation:
22.
The formula for perimeter is
P = 2 (length + Width )
= 2 ( 2x+3x+1)
= 2(5x+1)
The Formula for Area of a rectangle is
A= length x width
A= ![2x \times (3x+1)](https://tex.z-dn.net/?f=2x%20%5Ctimes%20%283x%2B1%29)
A=![6x^2+2x](https://tex.z-dn.net/?f=6x%5E2%2B2x)
Now we have to find the Perimeter and Area for x = 5
P = 2(5 x 5 +1)
P= 2(26)
P=52 units
A= 6 x 5 x 5 + 2 x 5
A= 150 + 10
A= 160 square units

![2 \times 10^5](https://tex.z-dn.net/?f=2%20%5Ctimes%2010%5E5)
Standard notation
![2 \times 10^5 = 200000](https://tex.z-dn.net/?f=2%20%5Ctimes%2010%5E5%20%3D%20200000)
Answer:
12... If there is an even ratio between the two, then there is an even amount, so you divide 24 by 2 and you have 12 chocolate and 12 vanilla cupcakes in the Grande box.

Answer:
The coordinates of ABCD after the reflection across the x-axis would become:
Step-by-step explanation:
The rule of reflection implies that when we reflect a point, let say P(x, y), is reflected across the x-axis:
- x-coordinate of the point does not change, but
- y-coordinate of the point changes its sign
In other words:
The point P(x, y) after reflection across x-axis would be P'(x, -y)
P(x, y) → P'(x, -y)
Given the diagram, the points of the figure ABCD after the reflection across the x-axis would be as follows:
P(x, y) → P'(x, -y)
A(2, 3) → A'(2, -3)
B(5, 5) → B'(5, -5)
C(7, 3) → C'(7, -3)
D(5, 2) → D'(5, -2)
Therefore, the coordinates of ABCD after the reflection across the x-axis would become:
