Answer:
x = 10
Step-by-step explanation:
given
4x - 10 = 3x ( subtract 3x from both sides )
4x - 3x - 10 = 3x - 3x ( simplify both sides )
x - 10 = 0 ( add 10 to both sides )
x - 10 + 10 = 0 + 10 , that is
x = 10

How much of the apples did Lucy use for her dessert?
Answer:
55 mph
Step-by-step explanation:
Let x represent Bob's speed. Then John's speed is x+10, and their respective times are found by ...
time = distance/speed
330/x = 390/(x+10) . . . . . . . the times are the same
330(x +10) = 390x . . . . . . . multiply by x(x+10)
3300 = 60x . . . . . . . . . . . . . subtract 330x
55 = x . . . . . . . . . . . . . . . . . . divide by the coefficient of x
Bob is driving at 55 miles per hour.
The description that best describes the strength and direction of the association between the variables is A. Strong positive.
A correlation is defined as a causative association between two or more variable, which can be used to make predictions about a given outcome.
The degree and direction of the link between the variables are best described by a strong positive correlation. R = 0.96 indicates that the independent variable raise the dependent variable by 0.96. R correlation ranges from 0 to 1, with 0 indicating the weakest connection and 1 indicating the strongest correlation.
As a result, 0.96 is a strong correlation. The correlation coefficient's minus and positive values indicate the direction of the relationship between the variables.

Answer:
= r
Step-by-step explanation:
First write down the equation they gave you:
l = Prt
You need to ask yourself what is being done to r. r in this case is being multiplied by two variable: P and t. To undo multiplication you divide, the set up for division:
I divided by the two numbers, so it would be easier. The P and T cancels out on the right and you are left with r. On the left, however, it stays the same because there are no like terms to solve with. You just leave as it is.
The result you get is:
