Given:
Line A: 2x + 2y = 8
Line B: x + y = 4
x = 4 - y
2(4-y) + 2y = 8
8 - 2y + 2y = 0
0 = -8
y = 4 - x
2x + 2(4-x) = 8
2x + 8 - 2x = 8
0 = 0
There is no solution.
Hi Brainiac
7/8 =?/48
Let's replace the unknown place by x
7/8 = x/48
Cross multiply
(7)(48)= (X)(8)
336 = 8x
Flip it
8x = 336
Divide both sides by 8
8x/8 = 336/8
x= 42
The answer is C
Now if you wanna see if the answer is good just replace 42 in blank space
7/8 = 42/48
Now didivde 7 by 8 and divide 42 by 48
7/8= 0.875
42/48= 0.875
The answer C is correct
I hope that's help:)
If you have questions please let me know :)
To calculate the area of a triangle, multiply the base and the height, then divide the product by 2.
7*8=56
56/2=28
Area=28 feet squared
S is the set of prime numbers that are less than 15. The correct solution in roster form is {1,3,5,7,9,11,13}. The answer is letter C. The rest of the choices do not answer the question above.
Answer : The correct option is (A) 68.
Step-by-step explanation :
As we are given that:
LN = 6x - 5
LM = x + 7
MN = 3x + 20
Now we have to determine the value of MN.
According to the question:
LN = LM + MN
Now putting all the given values in this expression, we get:
6x - 5 = (x + 7) + (3x + 20)
6x - 5 = 4x + 27
6x - 4x = 27 + 5
2x = 32
x = 16
The value of MN = 3x + 20 = 3(16) + 20 = 48 + 20 = 68
Therefore, the value of MN is 68.
