I havent done this stuff but I'm assuming x has to be equal to the number its being subtracted from so that the end result would be 0.

If angle EFH(5x+1)’ angle HFG(62 degrees) and angle EFG (18x+11) find each measurement
zloy xaker [14]

Answer:

∠EFH = 21°

∠HFG = 62°

∠EFG = 83°

Step-by-step explanation:

The diagram showing the angles has been attached to this response.

From the diagram, it can be deduced that;

Angle EFG = angle EFH + angle HFG

=> ∠EFG = ∠EFH + ∠HFG                -------------------(i)

From the question:

∠EFH = (5x + 1)°                    -------------(ii)

∠HFG = 62°                          -------------(iii)

∠EFG = (18x + 11)°                 -------------(iv)

<em>Substitute these values into equation (i) as follows;</em>

(18x + 11) = (5x + 1) + 62

=> 18x + 11 = 5x + 1 + 62

<em>Collect like terms and solve for x</em>

18x - 5x = 1 + 62 - 11

13x = 52

x = 4

Now, to get each measurement, substitute x = 4 into each of equations (ii) - (iv)

∠EFH = (5x + 1)°

∠EFH = (5(4) + 1)°

∠EFH = (20 + 1)°

∠EFH = 21°

∠HFG = 62°              [<em>Does not depend on x</em>]

∠EFG = (18x + 11)°

∠EFG = (18(4) + 11)°

∠EFG = (72 + 11)°

∠EFG = 83°

<u>Conclusion:</u>

∠EFH = 21°

∠HFG = 62°

∠EFG = 83°

Jessica and Josh are selling Entertainment Books to raise money for the art room at their school. Jessica received the prize for
Over [174]

Answer:

Josh sold 16 books and Jessica sold 240 books

Step-by-step explanation:

Given: Jessica sold 15 times more books than Josh.

           Together they sold 256 books

To Find : How many did each one of them sell?

Solution:

Let Jessica sold x books

Let Josh sold y books.

Since we are given that Jessica sold 15 times more books than Josh.

⇒x=15y --a

We are also given that  Together they sold 256 books.

⇒x+y=256 --b

Using substitution method

Put value of x from equation a in equation b

⇒15y+y=256

⇒16y=256

⇒y=\frac{256}{16}

⇒y=16

Thus Josh sold 16 books

Jessica sold books = 15y = 15*16=240

Hence  Josh sold 16 books and Jessica sold 240 books
