Answer:
Step-by-step explanation:
56. 6x = 132
x = 22
57. 2/3 = -8x
-24x = 2
x = -2/24= -1/12
58. 5/11x = 55
5x = 605
x = 121
59. 4/5 = 10/16x
4/5 = 5/8x
23 = 25x
23/25
60. 3 2/3x = 2/9
11/9x = 2/9
11x = 2
x = 2/11
61. 4 4/5x = 1 1/5
24/5x = 6/5
24x = 6
x = 6/24 = 1/4
Step-by-step explanation:
ok
5y -29 and 3y +19 are vertical angles so they are equal
sweet then equal and solve
5Y -29= 3y +19
2y = 48
y = 24
substitute in if needed.
then for 4x+5 and 3X +7
4X + 5 IS CORRESPONDING TO <3. asked <3 is supplementary to 3x+7 so:
4x+5 + 3x + 7 = 180
7x = 168
x = 24
<6 is corresponding to 3x +7 so they are equal
<6 = 3(24) +7 = 79
Answer:
Step-by-step explanation:
Parallel lines. A & B are corresponding angles and corresponding angles are equal.
∠A = ∠B
8x - 8 = 5x + 25
Add 8 to both sides
8x - 8 + 8 = 5x + 25 + 8
8x = 5x + 33
Subtract 5x from both sides
8x - 5x = 5x +33 - 5x
3x = 33
Divide both sides by 3
3x/3 = 33/3
x = 11
∠B = 5x + 25 = 5*11 + 25 = 55 +25 = 80
∠B = 80°
Perimeter of a rectangle = 2(l + w)
Length =
Width =
Perimeter = 2(3.61 + 1.41) = 2 x 5.02 = 10.04 units
