In order to calculate the length of highest piece, You need to calculate the Greatest common divisor of 672 & 960 which is 96
So, the length of highest piece would be 96 cm
Now, Number of pieces of Iron-sheet = 672 / 96 = 7
Number of pieces of Copper-sheet = 960 / 96 = 10
Hope this helps!
As the x value goes up by 1, the y value goes up by 3. If the x value skips from 4 to 20, it goes up by 16. This means that the y value has gone up by 16 * 3, or 48. 13 + 48 = A) 61
3-x15 ?? Or 3-x+15 I’m not so sure I’m really bad at this but I really want to try to help I’m sorry if u got it wrong it would be my fault sorry
Answer:
x = 1/2; y = 1/3
Step-by-step explanation:
2x + 3y = 2 Eq. 1
-6x + 12y = 1 Eq. 2
Eq. 1
2x + 3y = 2
2x = -3y + 2
x = -3/2 y + 1
Eq. 2
-6x + 12y = 1
De Eq. 1 sabemos que x = -3/2 y + 1
-6x + 12y = 1
-6(-3/2 y + 1) + 12y = 1
9y - 6 + 12y = 1
21y - 6 = 1
21y = 7
y = 7/21
y = 1/3
Eq. 1
2x + 3y = 2
2x + 3(1/3) = 2
2x + 1 = 2
2x = 1
x = 1/2
Respuesta: x = 1/2; y = 1/3
Answer:
Length = 49.5 unit and width = 49.5 unit
Step-by-step explanation:
Given as , Perimeter of rectangle = 198 unit
so ,as Perimeter of rectangle = 2× ( Length + width)
Or, 198 = 2 × (Length + width)
Or, 
= length + width
So, length + width = 99 unit
Now to make area maximum
Length × width = maximum
Or, (99 - width ) × width = maximum
99 Width - width² = maximum Let width = W
Now differentiate both side with respect to W
D(99W - W²)
= 0 as, constant diff is 0
So, 99 - 2w = 0
Or, w = 
Or, w = 49.5 unit and L = 99- 4905 = 49.5 unit Answer
