Answer:

-\frac{17}{24}

Step-by-step explanation:

distribute the negative

-\frac{7}{8} +\frac{1}{6} this might help to rearrange the fraction \frac{1}{6} -\frac{7}{8}

you want common factors for your denominator so you could 8 * 6 =48   but they have an easier common factor and that is 24

3*8=24 and 4*6=24

-\frac{7}{8} *\frac{3}{3}=-\frac{21}{24}

  \frac{1}{6} *\frac{4}{4}=\frac{4}{24}

now we can add these two fractions

\frac{4}{24} -\frac{21}{24} =-\frac{17}{24}

What is 6dm in a fraction
Verdich [7]
It all depends on what you are comparing it to... if you want what fraction of a meter it is...

There are 10 decimeters per 1 meter so 1 dm is 1/10 of a meter which means 6 dm = 6 × 1/10 = 6/10 = 3/5

6 dm = 3/5 m

a sign says that the price marked on all music equipment is 30% off the original price you buy an electric guitar for sale price
prohojiy [21]

The original price is $450.

<u>Step-by-step explanation:</u>

Step 1:

Given details, Discount%, D% = 30 and Selling Price, SP = $315

Step 2:

Write down formula for calculating the Original Price

Selling Price (SP) = Original Price (OP) - Discount (D)

Discount (D) = Original Price (OP) * (D%/100)

Step 3:

Substitute given values in the formula

315 = OP - D

D = OP \times30/100

D = 0.3 OP

Step 4:

Substitute value of D in the first formula

315 = OP - 0.3 OP

315 = OP (1 - 0.3) = 0.7 OP

Original Price, OP = 315/0.7 = $450

An airplane travels
givi [52]
Velocity (against wind) = 2,688 km / 4 hr = 672 km/hr
Velocity (with wind) = 3,208 km / 4 hr = 802 km/hr
psa means plane velocity in still air
ws means wind speed
psa -ws = 672
psa +ws = 802  We add both equations and get
2 psa = 1,474
plane velocity (in still air) = 737 km/hr

psa +ws = 802 so that means

wind speed = 802 -737 = 65 km/hr

Given a square with two vertices of one side located at -5,-3 and -5,12 in square units what is its area
borishaifa [10]

Answer:

<h2>225 units squared</h2>

Step-by-step explanation:

Lets find the distance (the side length of the square)

D=sqrt((x2-x1)^(2)+(y2-y1)^(2))

plug in the coordinates:

D=sqrt((-5-(-5))^(2)+(12-(-3))^(2))

D=sqrt(0^(2)+15^(2))

D=sqrt(15^(2))

D=15

Area of a square is side length squared

A=s^2

A=15^2

A=225 units squared
