Step-by-step explanation:

There are 2 1/3 inches in  1 2/5 groups of 1 2/3 inches.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

There are 1 2/5 groups of 1 2/3 inches.

Now,

Since, There are 1 2/5 groups of 1 2/3 inches.

Hence, The number of inches = 1 2/5 × 1 2/3

                                              = 7/5 × 5/3

                                              = 7/3 inches.

Thus, There are 2 1/3 inches in  1 2/5 groups of 1 2/3 inches.

Answer:

y = -2x - 4.

Step-by-step explanation:

The points marked are (-2,0) and (0,-4).

The slope of line =  (-4-0) / (0- -2)

= -4/2 = -2.

The y-intercept is at y = -4,

so the equation required is y = -2x - 4.

Answer:

y = - 2x - 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 2, 0) and (x₂, y₂ ) = (0, - 4) ← 2 points on the line

m = [tex]\frac{-4-0}{0+2}[/tex] = [tex]\frac{-4}{2}[/tex] = - 2

The line crosses the y- axis at (0, - 4) ⇒ c = - 4

y = - 2x - 4 ← equation of line

The approximate number of DVDs in Paulette’s collection after 14 months is 75 DVDs.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

We have,

let the collection of DVDs ne n and the time spend is m.

and, the Equation for the situation is

n = 1.8 m + 25

Now, the number of DVDs in collection after 14 months is

= 1.8 (14)+ 25

= 50.2

So, the total number of DVDs are

= 50 + 25

= 75

Seems like thier perimeters are equal.

Answer:

The dimensions of this rectangle are 65 in by 39 in ⇒ B

Step-by-step explanation:

Let us use the ratio method to solve the question

∵ The perimeter of the rectangle = 2(length + width)

∵ The perimeter of a rectangle is 208 inches

∴ 208 = 2(length + width)

→ Divide both sides by 2

∴ 104 = length + width

∵ The ratio  of its length to its width is 5: 3

∴ The sum of the ratios = 5 + 3 = 8

→ By using the ratio method

→  length  :  width  :  length + width

→  5           :  3         :  8

→  x            :  y         :  104

→ By using cross multiplication

∵ x × 8 = 5 × 104

∴ 8x = 520

→ Divide both sides by 8

∴ x = 65

∵ y × 8 = 3 × 104

∴ 8y = 312

→ Divide both sides by 8

∴ y = 39

∵ x and y represents the length and the width of the rectangle

∴ The length = 65 inches

∴ The width = 39 inches

∴ The dimensions of this rectangle are 65 in by 39 in

Step-by-step explanation:

Equation: 40(5+x)=70*5+0x

Solve:

40x=150

x = 15/4

15/4 gallons is the answer.

3.75 gallons of water should he added to 5 gallons of 70% sugar syrup to make the 40% syrup

A linear equation is given by:

y = mx + b;

where y, x are variables, m is the slope of the line and b is the y intercept.

Let x represent the amount of water in galloons needed to be added to make 40% sugar. Hence:

40% of (x + 5) = 70% of 5

0.4x + 2 = 0.7 * 5

0.4x = 1.5

x = 3.75

Therefore 3.75 gallons of water should he added to 5 gallons of 70% sugar syrup to make the 40% syrup
