                 (5/2 mile) ÷ (1/4 hour)

             =    (5/2)       x        (4/1)  mph

             =         (20 / 2)  =  10 mph

We can solve this to get the unit rate by doing this:-

5/2=1/4

5*4/2*1= 20/2

20/2=10

Or we could have done it this way:

5/2=2.5

2.5*4= 10

Either way we solve this....our answer will always be 10 miles per hour or 10 mph

2 5/7+4 3/5= help please
Ainat [17]

Answer:

7\frac{11}{35}

Step-by-step explanation:

2\frac{5}{7}+4\frac{3}{5}

add the whole numbers

2+4=6

combine the fractions

\frac{5}{7}+\frac{3}{5}

LCM is 35 because 7 * 5 =35

\frac{5}{7}=\frac{5\cdot \:5}{7\cdot \:5}=\frac{25}{35}

\frac{3}{5}=\frac{3\cdot \:7}{5\cdot \:7}=\frac{21}{35}

\frac{25}{35}+\frac{21}{35}=\frac{25+21}{35}

=\frac{46}{35}

change the improper fraction into mixed number

6+1\frac{11}{35}

=7\frac{11}{35}

After a hike, a group of students equally share 5 boxes of granola bars. Each box has 8 granola bars. Which algebraic expression
SIZIF [17.4K]

Answer: B.

First, we have to have a question for this problem to create a solution. So, the example sentence is how many granola bars does each student get.

Second, an algebraic expression has a variable in it. So since we are trying to find the number of students, the variable is s.

From looking at C and D, we can already eliminate them. This question has mostly multiplication and division words in it, so it can't be addition and multiplication.

Now, we only have A and B left. A tip on  how to figure this out is reading the word problem out thoroughly. I will use B as an example. 5 boxes of granola bars were multiplied by the number of granola bars each student got. From reading this, it makes more sense. But it does change the example sentence, though.

I hope this helped and this is the right answer!

Dmitry_Shevchenko [17]

Answer:

x=33

Each base angle measures 69 degrees

Step-by-step explanation:

the 2  base angles are equal so  the measure of 1 base angle = (180 - 42) / 2

=  69 degrees

2x + 3 = 69

2x = 66

x = 33
