Answer:
12
Step-by-step explanation:
A straight line is equal to 180. The line AB is 180 degrees. This means 174 + angle = 180 for the angle between point D and B. It must be 6 degrees. This is the same angle as the angle between point A and C.
Line CD is also straight and equal to 180. On the line are the angles, 4k + 90 + 3k + 6 = 180. Solve for k by combining like terms and then using inverse oeprations.
4k + 90 + 3k + 6 = 180
7k + 96 = 180
7k = 84
k = 12
Answer: 7x - 6
Step-by-step explanation:
- Since you are not aware what the number's value is, use a variable, as 7x since 7 is multiplied by an unknown number. Then, subtract 7x - 6.
Answer:
87
Step-by-step explanation:
The mean is 87, multipliy all the numbers then devide that number by 6!
Answer:
The sides are
6
inches,
8
inches and
10
inches
Explanation:
I'd suggest that the question should read 'The perimeter of a triangle is 24 inches. The longest side is 4 inches longer than the shortest side, and the shortest side is three-fourths the length of the middle side. How do you find the length of each side of the triangle?'
In this case the question can be answered. If
x
is the length of the middle side, then the shortest side is 3/4x and the longest side is 3/4x+4
x+3/4x+3/4x+4=24
10/4x=20
x=8
Then the shortest side is 6and the longest side is 10
Step-by-step explanation:
Answer:
9
Step-by-step explanation:
We have to multiply 60 by 15%
15% = 
= 0.15, hence
number of text = 60 × 0.15 = 9
