Given:
Rectangle: 320 x 190
triangle: base: 305
I'm assuming that the unit measure is in miles.

I found a map of Nevada and I figured that the length of the rectangle is serving as the height of the triangle.

Area of the rectangle = Length * width
A = 320 mi x 190 mi 
A = 60,800 sq. mi.

Area of a triangle = (height * base) / 2
A = (320 mi x 305 mi) / 2
A = 97,600 sq. mi / 2
A = 48,800 sq. mi.

Total Area = 60,800 + 48,800 = 109,600 square miles.

–3(5y – 4) ≥ 17 Solve and graph on a number line thanks
likoan [24]

Answer:

y\leq 1.93

Step-by-step explanation:

  • To know the value that y takes according to the inequation -3(5y-4)\geq 17, we must do some algebra.
  • First of all, we divide both terms by (-3), wich would change the direction of the inequality, as follow: (5y-4)\leq\frac{17}{(-3)} (at this point you should remember that dividing or multiplying an inequation by anegative number changes the direction of the inequality)..
  • This means that (5y-4)\leq 5.67. Then,we just have to add both sides 4, which yields 5y\leq 5.67+4.
  • Then 5y\leq 9.67, which means that, if we divide both sides by 5, we obtain the value of y: y\leq 1.93 (in this case, the direction of inequality does not change because 5 is possitive).
