Answer:

x=-2/3 y+ 5/3

Step-by-step explanation:

3x+2y+−2y=5+−2y

3x=−2y+5

3x/3 = -2y+5/3

x = -2/3 y+5/3

x=-2/3 y+ 5/3

Answer:

Step-by-step explanation:

r = 1.5 in ,    V = 56.52 in³

V = π × r² × h

56.52 = π × (1.5)² × h

56.52 = π × 2.25 × h

[tex]h=\dfrac{56.25}{2.25\pi}=\dfrac{25}{\pi}\ in=7.9577...\ in\approx8\ in[/tex]

Step-by-step explanation:

Just multiply everything inside the paranthese by what is outside of the parenthesis.

-2.4(1.5x) + 2.4(.9) ---------> i did addition because it is a double negative, equaling a positive

Answer:

B. 2x + 12 = 28

Step-by-step explanation:

x is representative of the wingspan of the vampire bat. suppose the ghost bat has a wingspan of 28 inches.

if the wingspan of a ghost bat is 12 more than twice the vampire bat's, then 2x + 12 is the equation used to find the ghost bat's wingspan. we already know the ghost bat's wingspan is 28, therefore the equation is 2x + 12 = 28

Answer:

$47.60

Step-by-step explanation:

7% of 680 = 0.07 × 680 = 47.6

$47.60

7% of 680 = 0.07 × 680 = 47.6

Answer:

Step-by-step explanation:

m = y2-y1 / x2-x1

-7/2 = -5 - 2 / x -3

-7/2 = -7 / x-3

x-3 = -7 * -2/7

x-3 = 2

x=5

The number x = 27/7.

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.

If a line passes through two points (3 ,2) and (x, -5) ,

then the equation of line is

y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)

To find the slope;

m =  (y₂- y₁) / (x₂ - x₁)

And m = -7/2 (given)

Now,

-7/2 = (-5+2)/(x-3)

Using cross multiplication,

-7x + 21 = -6

x = 27/7

Therefore, the x is 27/7.

Question:

There are 33.8 fluid ounces in a litre. There are 128 fluid ounces in a gallon. About how many litres are in a gallon?

Is your estimate larger or smaller than the actual number of litres in a gallon? Explain how you know

Answer:

It is larger

Step-by-step explanation:

Given

[tex]33.8\ fl\ oz = 1\ litre[/tex]

[tex]128\ fl\ oz = 1\ gallon[/tex]

Required

Estimate number of litres in a gallon

[tex]33.8\ fl\ oz = 1\ litre[/tex]

[tex]128\ fl\ oz = 1\ gallon[/tex]

Cross Multiply

[tex]128\ fl\ oz * 1\ litre = 33.8\ fl\ oz * 1\ gallon[/tex]

[tex]128 * 1\ litre = 33.8* 1\ gallon[/tex]

Divide both sides by 33.8

[tex]\frac{128 * 1\ litre}{33.8} = \frac{33.8* 1\ gallon}{33.8}[/tex]

[tex]\frac{128 * 1\ litre}{33.8} = 1\ gallon[/tex]

[tex]3.78698224852\ litre = 1\ gallon[/tex]

Approximate

[tex]3.787\ litres = 1\ gallon[/tex]

The estimate is larger than the actual litres to gallon conversion because, in standard units of conversion;

[tex]3.785\ litres = 1\ gallon[/tex]

Answer:

The area of the triangle is 13.5 square units

Step-by-step explanation:

The easiest way to find the area of of a triangle is to find the area of rectangle surrounding it, and divide by two.

In this case, we can use the bottom line and the distance from that to the top point as the side lengths of our "rectangle"

The bottom line has a length of 9, and the distance from that line to the top point is 3.  We can say then that the area of the triangle is half of three times nine:

3 × 9 ÷ 2 = 3 × 4.5 = 13.5

So the total area of the triangle is 13.5 square units

Answer:

 Perimeter of the polygon p = 24

Step-by-step explanation:

Step(i):-

Given the vertices of a polygon are

P(0,4) ,Q( 5,4) ,R( 5,-3) and S(0,-3)

The distance of PQ

 [tex]a = PQ = \sqrt{(4-4)^{2} +(5-0)^{2} } = \sqrt{25} =5[/tex]

The distance of QR

[tex]b = Q R= \sqrt{(-3-4)^{2} +(5-5)^{2} } = \sqrt{49} =7[/tex]

The distance of RS

[tex]c = RS = \sqrt{(0-5)^{2} +(-3+3)^{2} } = \sqrt{25} =5[/tex]

The distance of PS

[tex]d = PS = \sqrt{(0-0)^{2} +(-3-4)^{2} } = \sqrt{49} =7[/tex]

Step(ii):-

Perimeter of the polygon

       = sum of all sides of polygon

p = a+ b+ c+ d

p = 5+7+5+7

p = 24

Final answer:-

 Perimeter of the polygon p = 24

Answer:

1,172.5cm²

Step-by-step explanation:

Total surface area of a box = 2(LW + WH + LH)

L is the length = 11.5cm

W is the width = 7cm

H is the height = 1.5cm

Substitute

TSA = 2(11.5(7) + 7(1.5) + (11.5)(1.5))

TSA = 2(80.5+10.5+17.25)

TSA = 2(117.25)

TSA = 234.5cm²

Hence  the total surface area of a stack of five such compact disc boxes will be 5(234.5) = 1,172.5cm²

Answer:

x^2+2x-15

Step-by-step explanation:

Answer:

x² + 2x - 15

Step-by-step explanation:

Solve by using FOIL (First, Outside, Inside, Last). This distributes the numbers:

(x + 5)(x - 3)

Use FOIL:

x(x) + x(-3) + 5(x) + (5)(-3)

Simplify:

x(x) + x(-3) + 5(x) + (5)(-3)

x² + x(-3) + 5(x) + (5)(-3)

x² - 3x + 5(x) + (5)(-3)

x² - 3x + 5x + (5)(-3)

x² - 3x + 5x - 15

Combine like terms.

x² + 2x - 15

Your final answer would be x² + 2x - 15

Answer:

234 square inches

Step-by-step explanation:

We are given that

Length of book, l=11 in

Width of book, w=8 in

Height of book, h=1in

Additional area required to overlap=20 square inches

We have to find how many square inches of paper to make  cover of one book.

We know that surface area of cuboid

[tex]S=2(lb+bh+hl)[/tex]

Using the formula

Surface area of book

[tex]S=2(11\times 8+8\times 1+1\times 11)[/tex]

[tex]S=214 in^2[/tex]

Total paper used to make cover of one book

=Surface area of book +additional surface area

=[tex]214+20[/tex]

[tex]=234in^2[/tex]

Hence, Anwar will use paper to make cover of one book=234 square inches

Answer:

$5,400

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3.5%/100 = 0.035 per year,

then, solving our equation

I = 4000 × 0.035 × 10 = 1400

I = $ 1,400.00

The simple interest accumulated

on a principal of $ 4,000.00

at a rate of 3.5% per year

for 10 years is $ 1,400.00.
