Answer:
900 - 1= (31)(29)
Step-by-step explanation:
We need to factor 900 -1
We write each number in square form
900 can be written as 30^2
1 can be written as 1^2
Now we apply difference of square formula
a^2 - b^2 = (a+b)(a-b)
So 900 - 1= (31)(29)
I believe the answer is 12 because if but in y= Mx+b format you would get 600= 50x. Then to solve you would dived 600 by 50 and get 12
Answer:
10
Step-by-step explanation:
let a = amount of apple
let g = amount of grapefruit
14a+25g=340
a+g=2a-2
-a -a
g=a-2
plug this into your first equation
14a+25(a-2)=340
14a+25a-50=340
+50 +50
39a=390
a=10
you have 10 apples
Answer:
Here is what I did
Step-by-step explanation:
Multiply both sides of the equation by the denominator, 5.
3/5k (5)=3/10(5)
3k=15/10
Then divide by the coefficient, 3, to both sides of the equation.
3k/3=15/10/3
k=1/2
