Answer: 3(0.28)+0.38 y OR 0.84+0.38y

Step-by-step explanation:

Given : Jonathan goes to the store and purchases 3 pencils for $0.28 each, and y number of erasers for $0.38 each.

No. of pencils bough = 3

Rate of each pencil  = $0.28

Then , Money( in dollars) spent on pencils = No. of pencils x rate of each pencil.

3\times0.28

Also, No. of erasers = y

Rate of each eraser = $0.38

Then , Money(  in dollars) spent on erasers = No. of erasers x rate of each pencil.

y\times0.38=0.38y

Then , the expression that shows how much Jonathan spent ( in dollars)=

Money spent on pencils+Money spent on erasers

= 3(0.28)+0.38 y

= 0.84+0.38y

Hence , the required expression : 3(0.28)+0.38 y OR 0.84+0.38y

7x+8(x+1/4)=3(6x-9)-8 need a solution for this problem
valentina_108 [34]
7x+8(x+1/4) = 3(6x-9)-8
7x+8x+2      = 18x - 27 -24
15x + 2        =  18x - 51
       +51                        + 51
15x + 53      = 18x
-15x             = -15x
          53       = 3x
          17.66  = x

Find the point where the line crosses the x-axis. y = –5x + 5
Ronch [10]
Every point on the x-axis has y-coordinate 0.
Let y = 0, and solve for x.

y = -5x + 5

0 = -5x + 5

5x = 5

x = 1

The line crosses the x-axis at x = 1.
