This is an algebra problem pretending to be geometry. The perimeter is the sum of the sides. Geometry done.
3x + (2x + 1) + 2(x + 4) = 37
7x + 9 = 37
7x = 28
x = 4
Choice B
Answer:
The distance is 8 miles.
Step-by-step explanation:
Manuel's house, his parents house, and grandparents house can be expressed as the three vertices of a right angled triangle. Thus, Pythagoras theorem can be applied to determine the distance from Manual's house to that of his grandparents.
Let the distance from Manuel's house to that of his grandparents be represented by x, so that;
=
+ 
=
+ 
100 =
+ 36
= 100 - 36
= 64
⇒ x = 
= 8
x = 8 miles
Thus, Manuel's house is 8 miles from his grandparents house.
Answer:
1,2,3
Step-by-step explanation:
1x2x3=6
1+2+3=6 best answer
189 because 20.7 rounds to 21 and 9.18 rounds to 9
21 * 9 = 189
( 'x' is not 144 .)
The supplement of an angle is (180 - x) .
The problem says that (2/3) of 'x' is equal to (180 - x) .
180 - x = 2/3 x
Multiply each side by 3 :
( Note: 3 x 180 = 540 .)
540 - 3x = 2x
Add 3x to each side:
540 = 5x
Divide each side by 5 :
<u>x = 108°</u> .
