If a = b, then a - c = b - c
This can be proven because they are both equal to the same value.

A book has 150 pages and you read 3 pages per day.after a certain number of days,there are 60 pages left.write an equation to sh

kotegsom [21]

3x+60=150 can be used to determine the number of days you read. Solving the equation determines that you have been reading for 30 days.

Step-by-step explanation:

Total pages = 150

Pages per days = 3

Pages left to read = 60

Let,

x be the number of days.

According to given statement;

Total pages = Pages per day*number of days + Pages left to read

$150=3x+60\\150-60=3x\\90=3x\\3x=90\\$

Dividing both sides by 3

$\frac{3x}{3}=\frac{90}{3}\\x=30$

3x+60=150 can be used to determine the number of days you read. Solving the equation determines that you have been reading for 30 days.

If the area is 48 cm and the radius is of the circle is 4 cm then what is the central angle

Digiron [165]

Answer:

Step-by-step explanation:

Area of sector = (∅/360°) x πr²

Area of sector = 48cm²

radius = 4cm

π = 3.14

48 = (∅/360°) x 3.14 x 4 x4

48 = (∅/360°) x 50.24

48/50.24 =(∅/360°)

0.9554 = (∅/360°)

∅ = 0.9554 x 360 = 343.949≈343.95° ( these is when the angle is in degrees)

if it is radians

area of sector = 1/2r²∅

area of sector = 48

r = radius = 4

area of sector = 1/2r²∅

48 = 1/2 x 4 x4 x∅

48 = 2x4 x∅

48 = 8∅

∅ = 48/8 = 6 radians

the central angle in radians is 6

Mary is flying a kite and has let out 50 yards of kite string. Mary’s kite is directly above Erika.

ch4aika [34]

The distance of Erika from kite directly is 35.71 yards

Step-by-step explanation:

Considering the given situation as a right triangle with string as hypotenuse and the distance between both girls as base

So,

$h = 50\ yards\\b = 35\ yards$

As the triangle is a right triangle, we can use pythagoras theorem to solve this problem.

$h^2 = b^2 + p^2\\p^2 = h^2 - b^2\\p^2 = (50)^2 - (35)^2\\p^2 = 2500-1225\\p^2 = 1275\\\sqrt{p^2} = \sqrt{1275}\\p = 35.707\ yards$

Rounding off to nearest hundredth

=> 35.71 yards

Hence,

The distance of Erika from kite directly is 35.71 yards
