We need at least 3 informations.
They are similar to that of the requirements for the two triangles to be congruent.
1. Angle - Side - Angle
2. Side - Angle - Side
3. Angle - Angle - Side (this one is not easy for drawing)
4. Side - Side - Side and
5. Right angle - Hypotenuse - Side
Answer:
x = 5
Step-by-step explanation:
Answer:
Any equation shown in the explanation
Step-by-step explanation:
Hello!
Combining like terms means combining terms with the same variables.
So combing all x's, all y's, all numbers, etc.
2/3x - 9 - 2x + 2 = 1
combine the x's
-1 1/3 x - 9 + 2 = 1
combine normal numbers
-1 1/3 x - 7 = 1
Add 7 to both sides
-1 1/3x = 8
Make mixed number into improper fraction
-4/3x = 8
Multiply both sides by 3
-4x = 24
Divide both sides by -4
x = -6
The answer would be any of the equation I showed above
Hope this helps!
Answer:
Step-by-step explanation:
1). 10 = 
10(7 + x) = 1 + 7x
70 + 10x = 7x + 1
10x - 7x = 1 - 70
3x = -69
x = -23
2). 0.2 = 
0.2(12 + x) = 6 + 2x
2.4 + 0.2x = 6 + 2x
2.4 - 6 = 2x - 0.2x
1.8x = -3.6
x = -2
3). 0.8 = 
0.8(x + 0.5) = x
0.8x + 0.4 = x
x - 0.8x = 0.4
0.2x = 0.4
x = 2
4). 3.5 = 
3.5(0.5 - x) = 4 + 2x
1.75 - 3.5x = 4 + 2x
-3.5x - 2x = 4 - 1.75
-5.5x = 2.25
x = -
x = - 
Answer:
B
Step-by-step explanation:
You use FOIL (first, inner, outer, last). You then see what answer would get 47x for the middle...
(x-6)(8x+1) is the only one that gets 47x.
Then finish solving (x-6)(8x+1) to get 8x - 47x - 6
