Answer:
The value of z is 1.
Step-by-step explanation:
Given:
We need to solve the problem using distributive property.
Solution:
For the given equation we will apply distributive property;
By Definition of Distributive property which states that;
"The distributive property lets you multiply a sum by multiplying each addend separately and then add the products."
example = 
So we get;
Now by using Subtraction property we will subtract both side by 1050 we get;
Now Dividing both side by 21 by using Division property we get;
Hence The value of z is 1.
Answer:
Distance problems are word problems that involve the distance an object will travel at a certain average rate for a given period of time.
The formula for distance problems is: distance = rate × time or d = r × t.
Things to watch out for:
Make sure that you change the units when necessary. For example, if the rate is given in miles per hour and the time is given in minutes then change the units appropriately.
It would be helpful to use a table to organize the information for distance problems. A table helps you to think about one number at a time instead being confused by the question.
Step-by-step explanation:
Answer:
$28000
Step-by-step explanation:
12×1000 + 12×1500 = 12000 + 18000 = $30000
the shortfall is the difference between $58000 and $30000
58000 - 30000 = $28000
Answer:
The $2.85 jar is the better buy.
Step-by-step explanation:
Start by finding the two separate unit rates. Then compare them:
$2.85
---------- = $0.36/oz
8 oz
$5.65.
----------- = $0.38/oz
15 oz
The $2.85 jar is the better buy, as its unit cost is lower.
