Cesar can hike at 3 1/3 miles in 2 hours. Bella can hike 1/3 mile in 1/4 hour.
Svetlanka [38]

Answer:

Cesar goes 1 2\3 miles in an hour

Bella goes 1 1\3 miles in an hour

Cesar is hiking faster

Step-by-step explanation:

Cesar: you half 3 1\3 because you need to half the time of 2 hours to determine how far he goes in an hour. 3 1\3 halved is 1 2\3

Bella: You must multiply 1\3 4 times in order to get the 1\4 hour to a whole hour. 1\3 4 times is 1 1\3.

Speed: Cesar goes 1 2\3 mph while Bella goes only 1 1\3 therefore Cesar is going faster

Solve for w. 5w + 9z = 2z + 3w
Margaret [11]

Answer:

w = -7z/2

Step-by-step explanation:

Our goal is to isolate w

1. subtract 3w from both sides to get 2w+9z = 2z

2. Subtract 9z from both sides to get 2w = -7z

3. Divide both sides by 2 to get w = -7z/2

We cannot simplify further, so this is our answer.

Solve this equation (if it shows up)
puteri [66]
These 2 angles are vertical angles.

Vertical angles are equal.

Set up an equation where 2 angles are equal to each other.

Solve for 'x'.

6x+238 = 3x + 178

3x = 178 - 238 = -60

x = -60/3

x = -20
