Answer:

57%

Step-by-step explanation:

the table shows the following:

test scores for Test 1 = 62, 62, 66, 70, 70, 70, 78, 82, 82, 86

test scores for Test 2 = 68, 72, 72, 72, 72, 76, 80, 80, 80, 84, 88, 88

there are 7 tests with scores greater than or equal to 70 on test 1

there are 11 tests with scores greater than or equal to 70 on test 2

the percent change is the difference of the two amounts, 7 and 11, divided by the original amount, 7

4/7 = 57%

Answer:

p, m, n.

Step-by-step explanation:

It is given that,

n=p(m)

Here, p is the name of the function and its variable is m which is independent.

Independent variable : Whose value does not depend on another variable.

Dependent variable : whose value depends on the another variable.

Since the value of n depends on the value of p(m) which is a function of m, therefore n is a dependent variable which depends on the variable m.

∴ If n = p(m), p is the function name, m is the independent variable,  and n is the dependent variable.

Solve for x: 1/2x + 1/3x - 4 = 5/6(x + 6)
kobusy [5.1K]

Answer:

No solution

Step-by-step explanation:

Lets start by simplifying everything out, and then try to get all of the x's on one side of the equation.

1/2x + 1/3x - 4 = 5/6(x+6)

Simplify and distributive property

5/6x - 4 = 5/6x + 5

Lets subtract 5/6x from both sides to try and get rid of the x from the right side of the equation. (Now, as you may already see, is we try to get all of the x's on one side of the equation, the x's will cancel out, and we will be left with no solution.)

5/6x - 4 - 5/6x = 5/6x + 5 - 5/6x

Simplify

-4 = 5

Because we ended up with something in the form a = b and a ≠ b, there is no solution. (If a = b, then there would be an infinite number of solutions.)

I hope you find this helpful. Let me know if anything in my answer confuses you. Happy studying.
