The ratios that have a unit rate of 5 will be:
6 1/4 kilometers to 1 1/4 minutes.
1 kilometer to 1/5 minutes
1/3 kilometers to 1 2/3 minutes
<h3>How to calculate the value?</h3>
The ratios will be:
1. 6 1/4 to 1 1/4
= 6.25 : 1.25
= 5
2. 4 1/2 to 2
= 4 1/2 / 2
= 2.25
3. 4/5 to 5 minutes
4. 1 kilometer to 1/5 minutes
= 1 : 1/5
= 1 / 0.2
= 5
5. 3 1/10 : 3/10
= 10
6. 1/3 : 1 2/3
= 5
Therefore, the correct options are 1, 4 and 6.

Area of the pentagon: 342 cm2
Step-by-step explanation:
The figure of the pentagon is missing: find it in attachment.
The area of the pentagon can be seen as the area of 5 equal triangles, each of them having a base equal to the length of the side of the pentagon,
L = 14.1 cm
and the height of each triangle can be found by using Pythagorean's theorem:
The area of each of the 5 triangles is
Therefore, the area of the pentagon is 5 times this area:

Answer:
-45 =x
Step-by-step explanation:
1/5(4x-2.5) = 5(.4x+10) +3 1/2
Change all to decimal form
.2(4x-2.5) = 5(.4x+10) +3.5
Distribute
.8x - .5 = 2x +50 + 3.5
Combine like terms
.8x - .5 = 2x +53.5
Subtract .8x from each side
.8x-.8x - .5 = 2x-.8x +53.5
-.5 = 1.2x +53.5
Subtract 53.5 from each side
-.5 -53.5 = 1.2x +53.5-53.5
-54 = 1.2x
Divide each side by 1.2
-54/1.2 = 1.2x /1.2
-45 =x
Answer:x=13
Step-by-step explanation:
Since they are both corresponding angles you can create the equation
5x+21=86
Subtract 21 from each side
5x=65
Divide each side by 5
X=13
Answer:
Answer:
x + 2y = 2
x - 2y = -2
2x = 0
x = 0
0 + 2y = 2
2y = 2
y = 1
(0, 1)
Step-by-step explanation:
consistent and independent
