Answer:
5=25, 6=36 n=n×n
Step-by-step explanation:
If you look at the numbers side by side, the number on the right is just the number on the left multiplied by itself. You cannot find the exact answer for n but you can create an equation for it.
Answer:
The value of x is 3
Step-by-step explanation:
First, you must expand everything:
2(2x+1) - 3(x-1) = 8
2(2x)+2(1) - 3(x)+3(1) = 8
4x + 2 - 3x + 3 = 8
x + 5 = 8
Then, move all the unknown value to one side:
x = 8 - 5
= 3
Answer:
If I live in South Carolina then I live in Charleston
Step-by-step explanation:
Just switch them
Answer:
5 more than twice a number
2x + 5
.
is the same
=
.
8 less than 3 times the number
3x -8
.
2x + 5 = 3x -8
13 = x
x = 13
.
Check to see if this is right.
.
2x+5 = 2(13)+5 = 31
3x -8 = 3(13)-8 = 31
right.
.
Answer: The number is 13.
.
Done.
Answer:
LM=12
V =90
Step-by-step explanation:
4. If it is a parallelogram, the two sides have to be equal.
2x-6 = x+3
Subtract x from each side
2x-x -6 = x+3-x
x-6 =3
Add 6 to each side
x-6+6 = 3+6
x=9
LM =2x-6
= 2*9 -6
= 18-6
= 12
5.
<U + < T = 180 Adjacent corners in a parallelogram are supplementary
11x+2 + 12x-6 = 180
Combine like terms
23x -4 = 180
Add 4 to each side
23x-4+4 = 180+4
23x = 184
Divide by 23
23x/23 = 184/23
x=8
<V = <T Opposite corners in a parallelogram are equal.
<V = 12x-6
<V = 12(8) -6
<V = 96-6
<v =90
