Use the equation

-2 - 5 = -7
0 - -3 = 3

-4 - 1 = -5
0 - 5 = - 5

this is all i am going to tell you

think you can figure the rest out on your own

Hope i helped mate!

The length of a rectangle is 2 Inches less than three times its width, and its perimeter is 36 Inches. Find the width of the

elixir [45]

Answer: Width = 5 inches

Concept:

Here, we need to know the idea of the perimeter.

A perimeter is a path that encompasses/surrounds/outlines a shape.

Perimeter of rectangle = 2 (w + l)

w = width

l = length

If you are still confused, please refer to the attachment below for a graphical explanation.

Solve:

w = w

l = 3w - 2

P = 36 inches

Given formula

P = 2 (w + l)

Substitute the value into the formula

36 = 2 (w + 3w - 2)

Simplify values in the parentheses

36 = 2 (4w -2)

Divide 2 on both sides

36 / 2 = 2 (4w - 2) / 2

18 = 4w - 2

Add 2 on both sides

18 + 2 = 4w - 2 + 2

20 = 4w

Divide 4 on both sides

20 / 4 = 4w / 4

w = 5

Hope this helps!! :)

Find each measurement indicated. Round your answers to the nearest tenth. Please show your work. Part 2

uysha [10]

Answer:

4. 14.03 miles

5. 15.02 kilometers

6. 19.95 meters

Step-by-step explanation:

4. We need to use the law of sines, which states that for a triangle with angles A, B, and C and sides a, b, and c, respectively, then:

$\frac{a}{sinA} =\frac{b}{sinB} =\frac{c}{sinC}$

Here, a = 30, <A = 130, and <B = 21. So, let's plug these in:

$\frac{30}{sin130} =\frac{b}{sin21}$

b = AC = $\frac{30}{sin130}*{sin21}$ ≈ 14.03 miles

5. Here, c = 7, <C = 23, and <A = 123. We want to find BC, which is just a:

$\frac{7}{sin23} =\frac{a}{sin123}$

a = BC = $\frac{7}{sin23} *{sin123}$ ≈ 15.02 kilometers

6. Here, c = 22, <C = 88, and <B = 65. We want to find AC, which is just b:

$\frac{22}{sin88} =\frac{b}{sin65}$

b = AC = $\frac{22}{sin88} *{sin65}$ ≈ 19.95 meters

Hope this helps!

A house and a lot are appraised at $420000. If the value of the lot 3/4 of the value of the house, how much is the lot alone wor

34kurt

Hello from MrBillDoesMath!

Answer:

180000

Discussion:

Let H = house and L = lot. The Question tells us that H + L = 420000 and L = 3/4H. We are asked to solve for L

H + L = 420000 => L = 3/4H implies that H =4/3L

(4/3)L + L = 420000 => (4/3) + 1 = 7/3

(7/3)L = 420000 => multiply both sides by 3/7

(3/7)(7/3)L = (3/7)420000 => as (3/7)(7/3) = 1

L = 180000

Check:

H + L = 420000

H + 180000 = 420000

H = 420000 - 180000

H = =240000

Is L = 3/4H ?

Does 180000 = 3/4 ( 240000) ?

Does 180000 = (3* 240000)/4 = 720000/4 = 180000 Yes! so the answers check!

Thank you,
