You may write them separating the units and tens digits, and then use FOIL to add 4 easy tems. For example, let's compute 21\cdot 36:

21\cdot 36=(20+1)(30+6)=600+120+30+6 = 756

Mike hiked to a lake in 6.5 hours at an average rate of 3 2/5 miles per hour. Pedro hiked the same distance at a rate of 3 4/5 m
balandron [24]
We first need to find the distance.
The information about Mike will provide the distance we need to answer the question about Pedro.

We will use D = rt

Mike:

(6.5)((17/5) = D

22.1 miles = D

Pedro:

D = rt

22.1 = (19/5)t

We need to find t.

22.1 ÷ 3.8 = t

5.8157894737 = t

We now round off as instructed.

5.82 = t

It took Pedro 5.82 hours to reach the lake.

Recipe for 1lb of trail mix calls for 3.2 oz of cashews. How many ounces of cashews are needed to make 4lb of trail mix
Elanso [62]
\frac{1}{4} = \frac{3.2}{x}

Cross multiply..

1x = 12.8
Divide 1 from both sides

\frac{1x}{1} = \frac{12.8}{1}

x = 12.8
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Let's check our answer now..

\frac{1}{4} = \frac{3.2}{12.8}

Cross multiply

12.8 = 12.8

Your answer is 12.8 :)

AB lies on a number line. The coordinate of point A is -6. Given that AB= 20, what are the two possible coordinates for point B?
sukhopar [10]
The fact that you must remember is that these points lie on a plane that have a a distance that is ALWAYS an absolute value.  If point A lies on -6 you can have two points that are of a distance 20 points in either direction.  If moving the left, point B can have a value of -26 and moving to the right, point B will have a value of 14.  Hope this is clear!

Good luck!

The sum of two numbers is 49 and the difference between these two numbers is 9. What are these two numbers?​Shown working out pl
8_murik_8 [283]

Let numbers be x and y

ATQ

  • x+y=49---(1)

  • x-y=9---(2)

Adding both

\\ \sf\longmapsto 2x=58

\\ \sf\longmapsto x=\dfrac{58}{2}

\\ \sf\longmapsto x=29

Now putting value in eq(2)

\\ \sf\longmapsto x-y=9

\\ \sf\longmapsto 29-9=y

\\ \sf\longmapsto y=20
