Answer: 18, 19, 20
Step-by-step explanation:
3 consecutive integers = x, y and z
1st number is X
2nd number is Y which is X +1
3rd number is Z which is X +2
Write equation
X + 2Y = 16 + 2Z
Replace Y with X + 1 and Z with X + 2
So,
X + 2(X + 1) = 16 + 2(X + 2)
Distribute
X + 2X + 2 = 16 + 2X + 4
Combine like terms
3X + 2 = 2X + 20
Solve for X
3X + 2 - 2 - 2X = 20 + 2X - 2X - 2
X = 18 so, Y is 19 and Z is 20
What is the ratio of 5 rectangles and 13 circles?
A ratio can be written 3 ways, and when working with ratios we have to be very careful and put the answer the way the questions is asking.
Way # 1
a to b
Way # 2
a: b
Way # 3
a/b

Answer:
6/48 is the likely possibility that he will pull out a blue one.
Step-by-step explanation:
The first thing you will look at is how many blue there is and in this case there is 6. All you have to do (if it didn't already) is add up all of the paperclips and put the blue total number to get your answer. So if there was 49 but he drew out one to make it 48. So the answer is 6/48
The answer is the answer is 0.7 not just .7
Answer:
x - 3y = 8.
Step-by-step explanation:
Use the point-slope form of the equation of a line:
y - y1 = m(x - x1) where m = the slope and (x1, y1) is a point on the line.
So substituting the given values:
y - (-2) = 1/3(x - 2)
y + 2 = 1/3x - 2/3 Multiply through by 3:
3y + 6 = x - 2
x - 3y = 6 + 2
x - 3y = 8 <---- Standard Form.
