Answer:
x=7, y=16
Step-by-step explanation:
2x+5=x+12
2x=x+7
x=7
y-4=x+5
y-4=12
y=16
Answers:
5.) Yes it is, you add each one to itself to get the next number
6.) Yes, you subtract 5 from each number
7.) yes, you add 1.50 to each number
8.) Yes, you add 50 to each number
9.) No, they do not follow a pattern
10) Yes, you divide by 5 every time.
Answer:
If you need the expression: 2x^2-5x-3
If you need answers from a factored form: x=3 and x= -1/2
Step-by-step explanation:
(x-3)(2x+1)
2x^2+x-6x-3
2x^2-5x-3
Answer:
x =120
60,60,120,120
Step-by-step explanation:
The sum of the angles is 360
x + x+ 1/2x + 1/2x = 360
Combine like terms
3x = 360
Divide each side by 3
3x/3 =360/3
x =120
The 4 angles are 120, 120,60,60
From least to greatest
60,60,120,120
