Okay! 4/16= 0.25 because 16/16 = 1 and so that means 12/16 = 0.75 and 8/16 = 0.50 and 4/16 = 0.25 Hope this helped!
Answer:
8.125
Step-by-step explanation:
Just do 1 and 5/8 times 5
1)
45x^3+5x
the GCF is 5x because that is a factor of both.
The answer would be 5x(9x^2+1)
2)
u^2-5u+6
factoring is finding what multiplies to the last number to add to the middle number. Those numbers are -3 and -2.
the answer would be (u-3)(u+2)
3)
m^2-49
difference of perfect squares
answer is (m+7)(m-7)
4)
x^5+4x^4+3x^3
GCF is x^3 so it's x^3(x^2+4x+3)
Factor that and it's x^3(x+3)(x+1)
Answer:
x=-2, y=4. (-2, 4).
Step-by-step explanation:
2x+y=0
5x+3y=2
----------------
-3(2x+y)=-3(0)
5x+3y=2
-------------------
-6x-3y=0
5x+3y=2
---------------
-x=2
x=-2
2(-2)+y=0
-4+y=0
y=0-(-4)
y=0+4
y=4
