Answer:
10:18 10 gal of blue paint and 18 gal of yellow paint.
Step-by-step explanation:
Let the numbers be X and X+1.
X+2(X+1)=29
X+2X+2=29
3X=29-2
X=27/3
X=9.
Thus, the Numbers are therefore 9 and 9+1=10
i.e 9 & 10.
Thus, when 9 is added to (2*10=20), the result is 29.
P = 2(L + W)
P = 25
L = W + 3
now we sub and solve
25 = 2(W + 3 + W)
25 = 2(2W + 3)
25 = 4W + 6
25 - 6 = 4W
19 = 4W
19/4 = W
4.75 = W <== width = 4.75 cm (or 4 3/4 cm)
L = W + 3
L = 4.75 + 3
L = 7.75 <== length = 7.75 cm (or 7 3/4 cm)
Hey there!
We want to multiply a certain quantity by 2, so we will put the two outside of parentheses and put our variable (x) minus two inside the parentheses to represent this. This will all equal two.
2(x-6)=2
The unknown number is also 7.
I hope that this helps!
