Answer:
t = 17.5
f = 12
Step-by-step explanation:
interior corner angles in a square = 90 degrees
4t + 20 = 90
4t = 90 - 20
4t = 70
t = 17.5
7f + 6 = 90
7f = 90 - 6
7f = 84
f = 12
Answer:
224ft^3
Step-by-step explanation:
l*w*h= volume
Answer:
255 minutes
Step-by-step explanation:
306 can be subtracted by 102 a total of 3 times. We know that for every 102 miles = 85 minutes. So 85 * 3 = 255.
Answer: There are infinitely many solutions.
Step-by-step explanation:
Given, Two lines, A and B, are represented by the following equations:
Line A: 3x + 3y = 12
Line B: x + y = 4
By comparing to the equations and respectively , we have
Now ,
i.e.
It implies the gives lines are co-incident (linearly dependent).
That means it has infinitely many solutions.
So, the correct answer is "There are infinitely many solutions.".
So we should take x=0
1/2(0) - 1/3y = -3
0-1/3y= -3
y= -3 : -1/3
y= -1/3 *3/11 = 1
so the first is : x=0 , y=1
1/2 x - 0 = -3
1/2x=-3
x= -3 : 1/2
x=1/2 * 3/1 = 3/2 = 1,5
So here is x= 1,5 , y=0.
-----------------------------
The second equ
x-5y= 7
Let's take x as 0
0-5y = 7
-5y=7
y= 7/-5
y= -1,4
x= 0 . y= -1,4
Now let's take y=0
x- (5*0) =7
x-0=7
x=7
x=7 , y=0
