Answer:
Step-by-step explanation:
30 30 x 3 = 90
x 3
90
first multiply 4 x 5 = 20 bring down 0 then multiply 4 x 2 = 8 then add+2= 10
25 x 4 = 100
12 x 15 = 180
Answer:
-1
Step-by-step explanation:
2(.5n-3)=n-0.25(12-12n)
first you distribute whatever is on the outside of the parenthesis to the inside of the parenthesis
1n-6=n-3+3n
then you combine like terms and end up with
1n-6=-3+4n
add 6 to each side to get
n=3+4n
subtract 4n from each side to get
-3n=3
divide -3 from each side to get
n=-1

I believe the answer to this question is: In Picture.
Nothing, you can't simplify 39/8 more than that
Answer:
width=2 11\16
length= 3 13\16
Step-by-step explanation:
the width is unknown lets name it x
width=x
length=x±9\8
2[x±x±9\8]=13 1\4 cm
x± x =2x
2x×2=4x
9\8×2=9\4
4x±9\4=13 1\4
4x=13 1\4 -9\4
52\4-9\4=43\4
4x=43\4
43\4÷4=2 11\16
so x which is width =2 11\16
length 2 11\16 ±9\8=3 13\16
