Answer:
a= 6
Step-by-step explanation:
slope = (y2 - y1)/(x2 - x1)
3/8 = (3 - 0)/(a - (-2))
cross multiplying,
3(a + 2) = 3(8)
3a + 6 = 24
3a = 18
a = 18/3
a = 6
Answer:
8x + 9
Step-by-step explanation:
The total number of people splitting the cost equally = Rocco and five friends = 6 people
The total cost to play paintball can be represented by the expression (48x+54)
The cost for each person is calculated as: The total cost to play paintball/ Total number of people
= (48x+54)/6
= 48x/6 + 54/6
= 8x + 9
Therefore, the cost for each person is
8x + 9
Answer: Interval
Step-by-step explanation:
When there is a fixed unit of measure that means arithmetic operations like addition and subtraction can be done on it. So it is interval scale of measurement.
I think the thickness of the plank is 0.03m
Answer:
y=−2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
6y+2(3y−5)=−34
6y+(2)(3y)+(2)(−5)=−34(Distribute)
6y+6y+−10=−34
(6y+6y)+(−10)=−34(Combine Like Terms)
12y+−10=−34
12y−10=−34
Step 2: Add 10 to both sides.
12y−10+10=−34+10
12y=−24
Step 3: Divide both sides by 12.
= 
y=−2
