Need an answer for both plez.
Ilya [14]

Answer:

(2, 13)

Step-by-step explanation:

Since they both equal y, you can equal them to each other.

8x - 3 = 2x + 9

Subtract 2x from both sides.

6x - 3 = 9

Add 3 to both sides.

6x = 12

Now divide 6 on both sides.

x = 2

Now that we have found x, we need to find y. Just plug in x to the equations.

y = 2(2) + 9

y = 4 + 9

y = 13

Now, if the next equal has the same y, then both are true.

8(2) -3 = y

16-3=y

13 = y

So therefor, both x and y are true.

Veronica is choosing between two health clubs. Studio A has membership is $23.00 and a monthly fee $24.75. Studio B has a member
Dovator [93]

Answer:

14.02

Step-by-step explanation:

You'd have to write equations for the price per month for each club.

Let  x  equal the number of months of membership, and  y  equal the total cost.

Club A's is  y = 24x + 21.50 and Club B's is  y = 17.25 x + 41.00 Because we know that the prices,  y , would be equal, we can set the two equations equal to each other.

24x + 21.50 =17.25 x+ 41.00

subtract 21.50 both sides

. We can now solve for  x  by isolating the variable.

24x=17.25x+19.5

divide 17.25x

1.39x=19.5

divide 1.39 both sides

x=14.02

After five months, the total cost would be the same.

USING OLDER BROS ACC THIS IS HOW MUCH I NEED HELP PLEASE BE QUICK--------------------
lesya692 [45]
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.
