I think the answer is h=-24
Answer: h= 5.08
Step-by-step explanation:
In a parallelogram , the formula to find the area of the parallelogram is given by :-
, where b is the base and h is the height of the parallelogram.
Given : A=64 h=? b= 12.6
Substitute these values in the above formula , we get
Divide both sides by 12.6 , we get
∴ The missing variable : h= 5.08
Answer:
the interest rate is 92.86%
Step-by-step explanation:
270-140= 130
the %interest= (130/140)×100%
92.86%
X+2y=10
6x+6y=6 -> x+y=1
(x+2y=10)-(x+y=1)=y=9
x+(2*9)=10
x+18=10
x=-8 and y=9 -> c
Answer:
The perimeter is the distance all the way around the outside of a 2D shape. To calculate the perimeter, sum the lengths of all the sides.
Therefore, perimeter of the triangle = (2x - 8) + (2x + 5) + (30 - 3x)
Collect like terms: 2x + 2x - 3x - 8 + 5 + 30
Combine like terms: x + 27
Therefore, perimeter of triangle = x + 27
We are told that the perimeter is 25:
x + 27 = 25
Subtract 27 from both sides: x = -2
If x = -2, then the side with equation 2x - 8 = (2 x -2) - 8 = -12
A length cannot be negative, therefore the perimeter cannot equal 25.
