Think of the tens and the units separately:

16 x 34

= (10 + 6)(30 + 4)


Then we can distribute and get:

10(30 + 4) + 6(30 + 4)


And then further to get:

(10 x 30) + (10 x 4) + (6 x 30) + (6 x 4)


Each of these multiplications is easy enough to do in your head:

300 + 40 + 180 + 24


Add up the results:

300

180

1. To participate in a school trip, Kim had to earn $85 in one week. Kim could earn $8 per
vodka [1.7K]
It has given you that to earn $85 in one week. Kim could earn $8 per hour babysitting and $15 per hour for yard work with work time limited to 8 hours per week. Now we have to represent the variable X is the numbers of hours spent doing babysitting in the week. And Y represents the number of hours spent doing yard work in the week. The equation representing the condition on the total number of hours to be worked is: x+y= 8. The equation relating the number of hours working at each job toward the fund- raising goal is: 8x+ 15y= 85 and your final answer should be x= 5

Find the midpoint of a segment with the given endpoints.<br> W(-2,5), X(3,-17) =
Tema [17]

Answer:

The answer is

<h2>( \frac{1}{2}  \: , \:  - 6)</h2>

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

<h3>M = (  \frac{x1 + x2}{2} , \:  \frac{y1 + y2}{2} )</h3>

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

W(-2,5) and X(3,-17)

The midpoint is

<h3>M  =( \frac{ - 2 + 3}{2}  , \:  \frac{5 - 17}{2} ) \\  = ( \frac{1}{2}  \: , \:   - \frac{12 }{2} )</h3>

We have the final answer as

<h3>( \frac{1}{2}  \: , \:  - 6)</h3>

Hope this helps you
