If x is reduced by 1/3, 3x will be reduced by 1/3 x 3 = 1

Because y = 3x, y will also be reduced by 1.

The equation in the form y = mx +b, where x is the number of monthly minutes used and y is the total monthly of the A Fee and Fee plan is: y = (3/20)x + 32 and the total monthly cost is $173.75.

a. Equation

Slope = ( $123.5-$86)/(610-360)

Slope=37.5/250

Slope= 3/20

y = mx + b

Solve for "b"

$123.5 = (3/20)610 + b

$123.5  = 91.5 + b

b=$123.5-$91.5

b = 32

Equation:

y = (3/20)x + 32

b. Total cost

Total cost= (3/20)945+32

Total cost= 141.75+32

Total cost= $173.75

Therefore the equation in the form y = mx +b, where x is the number of monthly minutes used and y is the total monthly of the A Fee and Fee plan is: y = (3/20)x + 32 and the total monthly cost is $173.75.

A ratio in mathematics shows how many times one number is included in another. For instance, if a dish of fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six (that is, 8:6, which is identical to the ratio 4:3). (i.e., 8:6, which is identical to 4:3). The ratio of oranges to the overall amount of fruit is 8:14, while the ratio of lemons to oranges is 6:8 (or 3:4). (or 4:7). (or 4:7). A ratio can have any number of values, such as counts of people or things or measures of length, weight, time, etc. In most cases, both numbers must be positive.

Answer:

its b

Step-by-step explanation:

Among the 4,229,138 residents of Indiana aged 25 and older, the percentage of the residents aged 25 and older that have a degree is 31 %.

Percentage, which was adapted from the Latin word "per centum", which means "by the hundred", is a fraction or a ratio in which the value of whole is always 100. It is represented by the symbol "%".

The formula to get the percentage is:

Percentage = (Value / Total Value) × 100

Getting first the total value of the degree holders: 326,036 have an associate's degree, 623,200 have a bachelor's degree, and 348,807 have either a graduate or professional degree

residents with degree = 326,036 + 623,200 + 348,807

residents with degree = 1,298,043

If the total value of the residents aged 25 and older is 4,229,138 and among them, 1,298,043 have a degree, getting its percentage using the formula:

Percentage = (Value / Total Value) × 100

Percentage = (1,298,043 / 4,229,138) × 100

Percentage = (0.3069285041) × 100

Percentage = 30.69 %

Rounding off to the nearest whole number,

Percentage = 31 %

The area of the given parallelogram is: 9√3 sq. feet.

A parallelogram is a simple quadrilateral with two sets of parallel sides in Euclidean geometry. In a parallelogram, the opposing or confronting sides are of equal length, and the opposing angles are of equal size.

Area of a parallelogram = Base of the Parallelogram * Height

Now, given:

A parallelogram ABCD,

AB = 6 feet, AX = 3√3.   Angle A = 30°

To find: Area of the Parallelogram ABCD.

Finding: Here, AB = 6 feet = base

For height,

Height = perpendicular distance from X to AB

= AX(sinA)

Height = 3√3 (sin30) = 3√3 / 2

Thus, area of the parallelogram = [tex]\frac{3\sqrt{3}}{2}\times6= 9\sqrt{3}sq. feet.[/tex]

Hence, The area of the given parallelogram is: 9√3 sq. feet.

The translation of the given sentence into an equation is: 7(b + 3) = 1.

Variables can be used to represent an unknown quantity when translating statements into equation. The word "times" is represented as or means "×" (multiplication). "Sum" means addition as well.

Thus, the sentence given can be translated as shown below:

The unknown number is represented as variable b.

"The sum of a number (b) and 3" would be translated as: b + 3.

"Seven (7) times the sum of a number and 3 (b + 3)" would therefore be: 7(b + 3).

Therefore, translating the whole sentence into an equation, we would have:

7(b + 3) = 1.

The rows of small jars of salsa are increased by 4 times.

The rows of ounces of salsa are increased by 32 times.

The pattern in the column of the table is

y = 8x

Therefore x = 4 then y = 8(4) = 32

x = 8 then y = 8(8) = 64

x = 12 then y = 8(12) = 96

x = 16 then y= 8(16) = 128.

x = 20 then y = 8(20) = 160.

The pattern in the column of the table is

y = 8x

Therefore x = 4 then y = 8(4) = 32

x = 8 then y = 8(8) = 64

x = 12 then y = 8(12) = 96

x = 16 then y= 8(16) = 128.

x = 20 then y = 8(20) = 160.

The relationship between ounces of salsa and small jars of salsa using a unit rate is

4 ounces = 1 serving

y = 4x

If x = 1 then y = 4

If x = 2 then y = 4(2) = 8

If x = 3 then y = 4(3) = 12

If x = 4 then y = 4(4) = 16

If x = 5 then y = 4(5) = 20

The relationship using the unit rate is

48 ounces = 4 medium jars of salsa.

For 1 medium jars of salsa = 48/4 = 12 ounces.

1 medium jar of salsa = 12 ounces.

5 yellow tiles should be removed.

The original ratio of red tiles to yellow tiles as per the question :Ratio = 6:15. Now, after removal of red tiles, the numerator of ratio will become = 6 - 2. The numerator of new ratio will be 4. For yellow tiles, let the number of yellow tiles removed be x. So, the denominator or new number of yellow tiles will be 15 - x.

Now, relating the two ratio -

6:15 = 4:(15 - x)

Performing cross-multiplication to find the value of x.

6 × (15 - x) = 4 × 15

Performing multiplication on both the Left Hand Side and Right Hand Side

90 - 6x = 60

6x = 90 - 60

Performing subtraction to find the value of x

6x = 30

x = [tex]\frac{30}{6}[/tex]
