                $1.89 / 4 = ?

4 ounces  is 1/4 of the loaf......so they must be 1/4 of the total cost......can you do it now, blondie??

Here you go......

3/7 = 0.4285714285714287......

Do you see the answer ???

order of opperations is PEMDAS
-5+1 * 3 -(7-2^3)
First tackle the exponent in the Parenthesis ( makes life easier)
-5 + 1 * 3 -(7-8)
Next would be to continue with the distributive law, I like to put a 1 infront of the - sign like so:
-5 + 1 * 3 -1(7-8)
After distributing everything you should have this
-5 + 1 * 3 -7 + 8
Now you need to follow the order of PE"M"DAS, we need to multiply the 1*3 and when we do we get 3.
-5 + 3 - 7 +8
So let's now group the negatives on one side and the positives on another side to make it easier to read.
+ 3 +8 -5 - 7
okay so lets solve the positive numbers and then the negatives
+11 - 12
what's -12 + 11?
-1


 

because you add the opposite

so it would be 14.2+ 4.9

exponents are when you take something to a certain power 2² would be 4

****10^-2****

Nice answers, guys ........!!!

I think you might want the graph of this.....here it is :   https://www.desmos.com/calculator/zcktzf41ww

(17/5) / (13/3)  =

17/5  x  3/13  =

51 / 65

Good answer, Thehumancalculator    !!!!!

Your telling us what the variables equal, but no problem.

Number (2)  is confusing....are there 25 dealers or 30  ???

Cars   Dealers   Total

2          2               4

3          3               9

4          4             16

5          5             25

6          x             ??

7          2             14

8          1               8

9          1               9

10        2             20

Without taking "x" into cosideration, 105 cars have been sold by 20 dealers

If there are 25 dealers, x = 5 and the number of cars sold = 135

If there are 30 dealers, x = 10  and the number of cars sold = 165

$84.50 - $12.25 - $17.85 - $15.45 = $38.95

0.784615385

 12.25 + 17.85 + 15.45 = 45.55 

84.50 - 45.55= 38.95

Just to make it easier you would want to do 5 over 4. Then just divide both the denominator and numerator by 4 then you'll just get 0.8 over 1. So you'll have 0.8 salami for 1 oz.

Someone correct me if i'm wrong, i learned this in like 6th grade.

mean mode and range?

mean is when you add all the numbers in a group then divide by the number of numbers in the group

mode is when you put the numbers in least to greatest then find the middle number

range is the least number to the greatest number ex.  1, 53, 17, 4 the range would be 1-53

y = (2/5)*x // - (2/5)*x y-((2/5)*x) = 0 (-2/5)*x+y = 0 y-2/5*x = 0 // - y -2/5*x = -y // : -2/5 x = -y/(-2/5) x = 5/2*y x = 5/2*y

List the prime factors of each number. Multiply those factors both numbers have in common. If there are no common prime factors, the GCF is 1.

prime is something that is evenly divisble like 4 whereas compsite is something that is not like 17. 1 and 0 are neither
