1) Unknown info = amount of potting soil he bought last week
2). 28=2x+4
Where x=amount of potting soil he bought last week
3). 28=2x+4
-4 -4
---------------------
24=2x
/2 /2
----------------------
X=12
4) Emmanuel bought 12 lbs of potting soil last week
Let Casey's age be x
Brian's age will be -3 from 2 times x ( Casey's age ) so it will be 2x-3
Adam's age will be Casey's age (x) + 9 which is x+9
NOW the sum of all these ages is 46 so..
Casey's age + Brian's age + Adam's age = 46
x + 2x-3 + x+9 = 46
2x + x + x + 9 -3 = 46
4x + (9 - 3) = 46
4x - 6 = 46
now transfer the numbers on the left one by one to the other side( right )
4x = 46 - 6 ( always remember the sign of the number becomes the opposite when we transfer them to other side)
4x = 40
x = 40 / 4
x = 10
so x = Casey's age = 10
2x - 3 = Brian's age = 2 * 10 - 3
= 20 - 3 = 17
x + 9 = Adam's age = 10 + 9 = 19
Answer:
Store 2
Step-by-step explanation:
Given
1. $4.50 for 5 pounds
2. $1/5 for 1/3 pounds
3. $4.00 for 5 pounds
Required
Determine the store with the lowest unit rate
To do this, we simply divide the price by the weights in each store
For Store 1:
For Store 2:
For Store 3:
<em>Comparing the unit rates of the three stores, we can conclude that store 2 offers the least unit rate</em>
Answer:
you are right
Step-by-step explanation:
Yes, it's true.
<em>Every </em><em>rectangle</em><em> </em><em>is </em><em>a </em><em>parallelogram</em><em>,</em><em> </em><em>but </em><em>not </em><em>every </em><em>parallelogram</em><em> </em><em>is </em><em>rectangle.</em><em> </em>
So, every parallelogram's properties will be same to rectangle, but not every rectangle's property will be same as parallelogram.
