Answer:

132600

Step-by-step explanation:

I was always taught like this, and this should be the best estimate:

28 x 4417 --> 30 * 4420 --> 132600

Some other possible estimates with simpler values:

30 * 4400 --> 132000

30 * 4500 --> 135000

30 * 4000 --> 120000

Alejandra's Tapas Bar offers a menu consisting of $9$ savory and $5$ sweet dishes. You can also get a mix-and-match plate consis

Mariana [72]

Answer:

Step-by-step explanation:

Given that the number of savory dishes is 9 and the number of sweet dished is 5.

Denoting all the 9 savory dishes by $p_1, p_2,...,p_9$ , and all the sweet dishes by $q_1,q_2,...,q_5$ .

The possible different mix-and-match plates consisting of two savory dishes are as follows:

There are 9 plates with $q_1$ from sweet plates which are $(q_1, p_1), (q_1, p_2), ..., (q_1,p_9).$

There are 9 plates with $q_2$ from sweet plates which are $(q_2, p_1), (q_2, p_2), ..., (q_2,p_9).$

Similarly, there are 9 plated for each $q_3, q_4$ and $q_5.$

Hence, the total number of the different mix-and-match plates consisting of two savory dishes

$= 9+9+9+9+9= 9\times5=45$

A garden table and a bench cost $852 combined. The table is $98 less than the bench. What is the cost of the bench?

Citrus2011 [14]

Answer:

Step-by-step explanation:

b=bench

852=b+(b-98) since the table is less than the bench by 98$

852-b=b-98

950-b=b

950=2b

475=b

How would I solve 7r=-7/2? I know the answer is -1/2 I just don't understand how to get -1/2 as my answer.

Art [367]

7r=-7/2

divide both sides by 7 to get r by itself

(7r)/(7) = (-7/2)/(7)

if you don't quite see it, think of multiplying both sides by 1/7 instead (its the same thing as dividing by 7)

(7r)*(1/7)=(-7/2)*(1/7)

r=-1/2
