I know the number ypu have to fill in would be 15 I believe that is the commutative or associative property or something with addition
Answer:
x is approximately 25.83
Step-by-step explanation:
x + 25 + 5x = 180
6x + 25 = 180
6x = 155
x=25.83
0.92085175 radians
Let's first calculate the length of the diagonal of the base. Using the Pythagorean theorem:
b = sqrt(9^2 + 7^2) = sqrt(81 + 49) = sqrt(130) = 11.40175425
Now the length of the diagonal to the box. Once again, using the Pythagorean theorem:
d = sqrt(15^2 + 11.40175425^2) = sqrt(225 + 130) = sqrt(335) = 18.84144368
We now have a right triangle where we know the lengths of all three sides. The lengths are:
a = 15
b = sqrt(130) ≠11.40175425
c = sqrt(335) ≠18.84144368
we want the angle opposite to side a. So
tan(A) = 15/11.40175425 = 1.315587029
A = atan(1.315587029)
A = 0.92085175 radians
3(x+5)=8x~~~First we distribute (we multiply 3 by x and 3 by 5)
3x+15=8x~~~Remove 3x from both sides
-3x -3x
15=5x~~~~Turn this equation around so x is on the other side
5x=15~~~Divide by 5x
÷5x ÷5x
x=3
Answer:3980
Step-by-step explanation:
We know hg here refers to hectogram and its conversion to gram is given by
1 hectogram is equal to 100 gm
therefore 39.8 hg simply means 3980 gm
Thus 39.8hg=3980 gm
