Solve the equation. −2 1/4=r−4/5 will give brainiest for the first correct answer!!!
STatiana [176]

Answer:

r = -1 9/20

Step-by-step explanation:

-2 1/4 = r - 4/5

Switch sides:

r - 4/5 = -2 1/4

Add 4/5 to both sides.

r = -2 1/4 + 4/5

Change the mixed numeral into a fraction:

r = -9/4 + 4/5

The LCD is 20.

r = -45/20 + 16/20

r = -29/20

r = -1 9/20

The answer is 1 km
————————————-

Proofs:

Area of a rectangle=length x width

Area of rectangle= 4kmE2
Length of rectangle= 4km
Width of rectangle= X

4=4(x)

Find x

4=4(1)


Therefore the width of the rectangle= 1km

2a(5-b)=3b+7 solve for b<br> Step by step
Sidana [21]
<span>2a(5-b)=3b+7

<em>[open bracket]</em>
10a - 2ab = 3b + 7

<em>[solve for b, so we need to move all terms with b to the left]</em>
<em>[-3b on both sides]</em>
10a - 2ab - 3b = 3b + 7 - 3b
10a - 2ab - 3b = 7

<em>[move all those without b to the right]</em>
<em>[-10a on both side]</em>
10a - 2ab- 3b - 10a = 7 - 10a
-2ab - 3b = 7 - 10a

<em>[divide by -1 through to change b to be positive]</em>
2ab + 3b = 10a - 7

<em>[take b out as the common factor]</em>
</span>b(2a + 3) = 10a - 7<span>

<em>[divide by (2a+3) through]</em>
b = (10a -7)/(2a+3)

Two cargo ships are sailing a direct course into harbor. Ship A is 22 miles from harbor. Ship Bis sailing into harbor on a cours
s344n2d4d5 [400]

Answer:

The distance of ship B from the Harbor is 32.26 miles

Step-by-step explanation:

Hello, great question. These types are questions are the beginning steps for learning more advanced Equations.

I have added a visual aid of the problem. As we can see the courses of both ship to the harbor forms a triangle with ship B being the hypotenuse. Since we are given the distance of the course for ship A and the angle between both ships, we can use this information with the <u>COSINE operator</u> to solve for the length of the course of ship B.

cos(x) = \frac{adjacent}{hypotenuse}

cos(47) = \frac{22miles}{hypotenuse} .... flip both fractions.

\frac{1}{cos(47)} = \frac{hypotenuse}{22miles} .... multiply both sides by 22

\frac{22mi}{cos(47)} = hypotenuse

32.26mi = hypotenuse = B

So the distance of ship B from the Harbor is 32.26 miles

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
