My teachers taught me a trick make a C from the top to bottom
so 5 1/2 would be
5 times 1 + 2 so denominator stays the same so it 7/2.
bottom one is 22/4
make a C from top to bottom and multiply outer number to top add the bottom to that then keep denominator the same.
Hope i helped.
Answer:
um I did this in my head but -20/3
Step-by-step explanation:
-6/5N × -5/6= 8× -5/6
simplify
n= 4/1× -5/3
n= -20/3

Answer:
The cost of desktop before finance charge was $1750.
The cost of laptop before finance charge was $1900.
Step-by-step explanation:
Let us assume this is a simple interest scenario.
Let D be the cost of desktop
Let L be the cost of laptop
Given- the laptop cost $150 more than the desktop.
So, 
The total finance charge for 1 year is given by :
Substituting the value of L here, we get;
=>
=> 
=> 
=> 
D = $1750
As
So, 
L = $1900
We can check this :
=> 
=> 
So, the cost of desktop before finance charge was $1750.
The cost of laptop before finance charge was $1900.
Answer:
false its x^6/9
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Let's call the shortest side a. The longest base, b, is 8cm longer than a. The height, h, is 2cm longer than a.
b = a + 8
h = a + 2
A = (a + b)h/2
48 = (a + (a+8))(a+2)/2
= (2a+8)(a+2)/2
= (2a^2+12a+16)/2
48 = a^2+6a+8
a^2+6a-40=0
Now, we factor this:
(a + 4)(a - 10)=0
a = -4, 10
a (length) cannot be a negative no. so the only possible answer is a = 10.
b = 10 + 8 = 18
h = 10 + 2 = 12
The answer is B
Hope this helps!
