Answer:
y = 20 - x
Step-by-step explanation:
Perimeter of a rectangle = 40 units
2 * ( length + width) = 40
2* (x + y) = 40 {Divide both sides by 2}}
x + y = 40/2
x + y = 20 {Subtract x from both sides}
y = 20 - x
Answer:
z = 473
Step-by-step explanation:
So the equation looks like this:
z-303=170
So in order to only get the variable z on one side and the numbers on the other we are going to have to add 303 to both sides of the equal signs:
z - 303 = 170
+ 303 +303
z = 473
So the answer to what the variable z equals is 473, so how do we know if 473 is the answer? Well we substitute 473 where the z variable is in the equation and solve it:
z-303=170 or (473) - 303 = 170
and if you subtract 303 from 473 you will get 170 as your answer
I hope this helps you!
Based on the image and the exercise, we can see that the congruency can be proven with SAS.
Answer: B.
Of course for a rectangle A = L × W and we need to be careful about the units.
Here that's
18900 sq cm = L × 180 cm
where the area's in sq cm so we converted the width. We get
L = 18900 / 180 = 105 cm
We're asked for the result in meters, so that's
Answer: 1.05 m
The perimeter of the outer rectangle is
18.4 m + 32.5 m + 18.4 m + 32.5 m = 101.8 m
Answer: 101.8 m
The area of the seating space is the big rectangle minus the small rectangle,
A = 18.4(32.5) - 15(28) = 178 sq m
Answer: 178 sq m
