Answer:

yes

Step-by-step explanation:

because 9*4=36 and well it's 36=32*? so 36-32 is 4

So well the solution is x=4

Answer:

Yes, it is.

Explanation:

For x = 4 to be a solution of the given eqⁿ, it must satisfy it. That is,

9x = 32 + x => 8x - 32 = 0

=> f(x) = 8x - 32

At x = 4,

f(4) = 8(4) - 32 = 32 - 32 = 0

Since, f(4) = 0, thus, x = 4 is a solution to the given eqⁿ.

Nat2105 [25]

Answer:

The number is 385.

Step-by-step explanation:

Digit in ones place = 5

Let the digit in tens place be x

Let the digit ion hundreds place be y.

Digit on tens place is 3 plus the digit in my ones place:

x = 3 + 5 = 8

Digit on hundreds place is 2 less that the digit in my ones Place :

y = 5 - 2 = 3

(yx5) = (385)

The number is 385.

an NFL team kicker misses 2 out of every 11 field goals if he missed 8 filed goals throughout the season how many did he attempt
Aleks [24]
For this equation, you want to do it in fractions/ratios to properly solve it. You would have his average misses out of every field goal and his real missed attempts over total. It would look like this

\frac{2}{11}  =   \frac{8}{x}

You want to solve for x since x is the total amount of field goals that he attempted. You can do this by doing cross multiplication:

(2)(x) = (8)(11)

From here you can get:

2x = 88

Divide each side by 2 to isolate x and you get:

x=  44

So he made a total of 44 field goals.

The experimental factor that is manipulated; the variable whose effect is being studied is called ____________
lorasvet [3.4K]

Answer:

The experimental factor that is manipulated; the variable whose effect is being studied is called <u>independent variable.</u>

Step-by-step explanation:

Consider the provided information.

In an experiment, the two principal variables are the independent and dependent variable.

An independent variable is the variable that is altered or controlled to test the effects on the dependent variable in a scientific experiment.

The variable which is tested and measured in a scientific experiment is a dependent variable.

From the above definition: The experimental factor that changed or controlled in a scientific experiment is called independent variable.

Therefore, the complete statement is: The experimental factor that is manipulated; the variable whose effect is being studied is called <u>independent variable.</u>
