X+y = 4, therefore y = 4-x when you rearrange the equation.
You can subsitute this in: x-(4-x) = 6
-4+x = 6-x
x=10-x
2x = 10
x = 5
Substitute x into the previous equation:
5+y = 4
y = 4-5
y = -1
Answer: y=6
Step-by-step explanation:
First distribute... 9p-36=18
then add 36 to the 18 to help isolate the variable..
9p=54
then to get the variable by itself divide 54 by 9 and get 6
13.3cm rounded to the nearest 10th
Answer:
Width = 12 in
Length = 16 in
Step-by-step explanation:
Let, the Width of the rectangle = w in
Now, the length of the rectangle = (w + 4) in
Now, Perimeter = 56 in
Also, we know that
Perimeter of the Rectangle = 2 (Length +Width)
or, 2 (Length +Width) = 56
⇒ 2(w + 4 +w) = 56
or, 4w =56 -8
width = 12 in
So, Length = w + 4 = 12 + 4 = 16 in
Answer:
3/5
4/3
2/1
3/1
Step-by-step explanation:
turn them to ratios and fractions and try to simplify
3/5=3/5
4/3=4/3
2/1=2/1
6/2=3/1
so put the end results in order
so all of them have a bigger numerator than denominator, except one. 3/5. Thats the slowest one.
4/3 isn't quite 2 wholes, but 2/1 is, so 4/3 is second last and 2/1 is second.
3/1 is the first.
