Answer:
Multiply the first bracket by 3
Multiply the second bracket by -2
3x+3=-2x+2-4
3x+2x+3=-2x-2 negative (-) number and positive number (+)= negative number
Just rearranging
5x+3=-2
5x+3-3=-2-3
5x=-5
Dividing by 5
5x/5=-5/5
x=-1
Check answer by using substitution method
3(-1+1)=-2(-1-1)-4
0=-2(-2)-4 negative number and negative number = positive number
0=4-4
0=0
Answer is x=-1
The volume of the large cylinder will be twice the volume of the small cylinder.
<u>Step-by-step explanation:</u>
Let the radius of the cylinder be 'r'
Let the height of the cylinder be'h'
Volume of the small cylinder=π r² h
Volume of the large cylinder= π r² (2h)
Volume of large cylinder/volume of small cylinder= 2/1
The large cylinder volume is twice the volume of the small cylinder.
Answer:
1/6 as an decimal would be, 0.1666 Continued
Step-by-step explanation:
Each of the triangles are equal in base length, height, and area<span>. Remember the formula for the </span>area<span> of a triangle. The </span>area<span> of any triangle is 1/2 times the length of the base (which, in the </span>polygon<span>, is the length of a side) multiplied by the height (which is the same as the apothem in </span>regular polygon<span>).

Answer:
4 books
Step-by-step explanation:
The cost for one used = $2.27
The question requires you to find the number of books that could be purchased with $10
Let assume the cost for a single used book to be $ t
If you have $ x in your pocket then the number of books you can purchase with $ x will be;
number of books= $ x/ $t.............................(a)
Applying this expression to the question;
$t= $2.27
$ x= $10
number of books = $10/$2.27 = 4.405 = 4 books
