Find the unknown value in the proportion x∕32 = 38∕64.
Question 4 options:

A)

19

B)

38

C)

54

D)

76

Answers

Answer 1
The answer is A. 19 since 32 is half of 64 so half of 38 is 19
Answer 2

Answer:

x=19

Step-by-step explanation:

This can be found in two ways.

Way #1

Since 32 is half of 64, divide 38 in half to get the missing number, or 19.

Way #2

Solve for x.

x/32 = 38/64

(Solve the expression on the right side)

x/32 = 0.59

(Multiply both sides by 32 to isolate the variable.)

x= 18.88 --> 19.

Really hoped this helped

The expression Mr smith will earn in a day is e= 75 + 35c.

What is expression?

A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:

An absolute numerical number is referred to as a constant.Variable: A symbol without a set value is referred to as a variable.Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.Coefficient: In an equation, a coefficient is a number that is multiplied by a variable.

Given:

Mr smith earns $75 a day plus $35 for each.

if e is the amount he earned,

and c is the number of cars he sold

So, the amount he earned

e= 75 + 35c

Hence, the expression is e= 75 + 35c.

The area of the garden is 9 km²

Step-by-step explanation:

If the garden is a square, that means that it's side length is one fourth of the total perimeter, giving us a length and width of 3km

That means that it's area is 3km × 3km, or 9km²

144 km because all sides of a square are equal and length times breadth is the area

Identify whether the variable in the information below is qualitative or quantitative. Government agencies carefully monitor water quality and its effect on wetlands (Reference: Environment Protection Agency Wetland Report EPA 832-R-93-005). Of particular concern is the concentration of nitrogen in water draining from fertilized lands. Too much nitrogen can kill fish and wildlife. Twenty-eight samples of water were taken at random from a lake. The nitrogen concentration (milligrams of nitrogen per liter of water) was determined for each sample.

Answers

Answer: quantitative

Step-by-step explanation:

Measured variables in statistics may be subdivided into quantitative or Qualitative variables depending on whether the variable in question is numeric or non-numeric. Variables which are designed to evaluate on the basis of Number or quantity may be termed as quantitative variables while those which measure attribute and are used for characterization are called Qualitative variables. In the scenario above, the variable is concerned with the determination of concentration of nitrogen draining into water bodies, concentration follows that numeric calculations be Made in other to determine the amount of nitrogen in milligram per Litre in a particular water body in other to prevent its effect on wildlife which could result from excessive concentration in water bodies.

The solution of given inequality satisfies the ( -2,-2) , (4 ,0) and (-2,0)

                     

Step-by-step explanation:

Given inequality

                      x - 3y < 5

a) From the graph we will choose point  x=-2 and y=-2

                    x - 3y < 5

                  -2 - 3(-2) < 5

                  -2 + 6 < 5

                    4 < 5

b)  From the graph we will choose point  x= 4 and y= 0

                x - 3y < 5

               4 - 0 < 5

                 4 < 5

c)  From the graph we will choose point  x= -2 and y= 0

                x - 3y < 5

               -2 - 0 < 5

                 -2 < 5

3x+9=5x+21

What is x

Answers

Answer:

Simplifying
3x + 9 = 5x + 21

Reorder the terms:
9 + 3x = 5x + 21

Reorder the terms:
9 + 3x = 21 + 5x

Solving
9 + 3x = 21 + 5x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-5x' to each side of the equation.
9 + 3x + -5x = 21 + 5x + -5x

Combine like terms: 3x + -5x = -2x
9 + -2x = 21 + 5x + -5x

Combine like terms: 5x + -5x = 0
9 + -2x = 21 + 0
9 + -2x = 21

Add '-9' to each side of the equation.
9 + -9 + -2x = 21 + -9

Combine like terms: 9 + -9 = 0
0 + -2x = 21 + -9
-2x = 21 + -9

Combine like terms: 21 + -9 = 12
-2x = 12

Divide each side by '-2'.
x = -6

Simplifying
x = -6

God bless you and I hope this helps :)

Answer:

X = -6

1. 3x + 9 = 5x + 21

2. Subtract -5x from both sides

3x + 9 - 5x = 5x + 21 - 5x

3.-2x + 9 = 21

4. Subtract 9 from both sides

-2x + 9 - 9 = 21 - 9

5.-2x = 12

6. Divide both sides by -2

-2x/-2 = 12/-2

7. x= -6
