Answer:
60
Step-by-step explanation:
Since the perimeters are equal then:
(3x + 3) * 4 = (x + 8) * 5
12x + 12 = 5x + 40
7x = 28
x =4
Perimeter of square = (3*4 + 3) * 4 =
(12 + 3) * 4 = 60
Perimeter of pentagon = (4 + 8) * 5 =
(12) * 5 = 60
The answer is 60
Answer:
-35
Step-by-step explanation:
15(x-7) + 4 = 10(x-7) +4
15x + 105 + 4 = 10x -70 + 4
15x + 109 = 10x - 66
-10x + 109 = -66
5x+ 109 = -66
-109 = -109
5x = -175
divide -175 by 5
Supplementary angles are angles whose sum is equal to 180°.
Let one angle be x
The other angle is said to be 26°more than the other so it is x + 26
x + (x+26) = 180
x + x + 26 = 180
2x = 180 - 26
2x = 154
x = 154/2
x = 77
1st angle, x, is equal to 77°
2nd angle, x + 26°, is 77° + 26° = 103°
77° + 103° = 180°
180° = 180°
Answer: 10 Inches
Step-by-step explanation:
Answer:8.3 repeating
Step-by-step explanation
First, subtract 47 by 32.
Then, multiply that difference by 5/9.
For ex:
47-32=15
15 x 5/9=8.3333333 and so on
