45/35＝54/54－x
9/7＝54/54－x
9(54－x)＝378
54－x＝42
x＝12
Hope my answer helped u :)
Answer:
W = 4.95
Step-by-step explanation:
You want to start by writing down what you know, and forming a system of equations.
L= length W= width
2L+2W=14.7
L= 2.4
On the left side of the equation, you're adding all your side lengths, and on the right, is the total perimeter. (Also could be written L+L+W+W = 14.7)
You would then substitute L from the bottom equation into the top equation to get:
2(2.4) +2W=14.7
Solving:
4.8+2w=14.7
W= 4.95
To check your answer simply add all the sides together and make sure it equals your perimeter. You can also plug W and L back into the original equation.
Step-by-step explanation:
The scale factor is 12/6 = 10/5 = 2.
Well 41 divided by 6 is 6.8333333333333 so you just need to subtract .833333333333

Answer:
1 = 115°
2 = 115°
3 = 65°
Step-by-step explanation:
P=65, so S (3) =65
360-65-65=230
230/2=115
Q (1) = 115
R (2) = 115
