Step-by-step explanation:

2/3 (12x+30)-12=4/10 (15x+10)

30×2/3 (12x+30)-12×30=4/10 (15x+10)×30

10(12x+30)-360 =12 (15x+10)

120x+300-360=180x+120

300-360-120=180x-120x

-180=60x

-180/60=60x/60

-30=x

Which graph shows the solution to the system of linear inequalities?<br> y&lt; 2x-5<br> y&gt;-3x + 1
trapecia [35]

Answer:

See explanation

Step-by-step explanation:

Plot the solution sets to both inequalities.

1. For the inequality y First, plot the dotted line y=2x+5 (dotted because sign is without notion "or equal to"), then choose correct part by substitution coordinates of the origin.

2\cdot 0-5=-5

so the origin does not belong to the needed part. Shade the part, which does not include origin.

2. For the inequality y>-3x+1. First, plot the dotted line y=-3x+1 (dotted because sign is without notion "or equal to"), then choose correct part by substitution coordinates of the origin.

-3\cdot 0+1=1>0

so the origin does not belong to the needed part. Shade the part, which does not include origin.

3. Find the common region of these two shaded parts - this is the solution to the system of two inequalities.

Answer:

The answer to your question is:  9.01 x 10⁸ ice cream cones

Step-by-step explanation:

Data

# of ice cream cones = 1700

5.3 x 10 ⁵ minutes ---------- 1 year

# of ice cream cones purchased in one year = ?

                              1700  cones ---------------------  1 min

                                 x                ----------------------  5.3 x 10 ⁵ minutes

             x = (5.3 x 10 ⁵)(1700)/1 = 901 000 000 ice cream cones

In scientific notation

                                   9.01 x 10⁸ ice cream cones
