I need someone to solve this
LUCKY_DIMON [66]

Answer:

?? = 900

Step-by-step explanation:

Solve algebraically

let x be ball and y be cube

x + y = 100

x - y = 80

xy = ??

We can solve by elimination. Eliminate one of the variables by adding OR subtracting the entire equations. I will add.

.     x + y = 100

<u>+    x - y = 80</u>       y + - y = y - y = 0; The variable is eliminated

.        2x = 180      Divide both sides by 2 to isolate x

.          x = 90

Substitute x = 90 into one of the equations.

x + y = 100

90 + y = 100  Isolate y by subtracting 90 from both sides

y = 100 - 90

y = 10

Find xy = ?? by substituting y for 10 and x for 90.

xy = (90)(10) = 900

Therefore the value of ?? is 900.

Find the exact area of the shaded please helppp ILL GIVE BRAINLIESTTTTTT
musickatia [10]

Answer:

The exact area is 5\pi

Step-by-step explanation:

The area of the major circle is subtracted from the area of the minor circle (blank)

Major circle

r=\frac{6}{2} =3

A=\pi r^{2} =\pi (3)^{2} =\pi (9)=9\pi

Minor circle:

r=\frac{4}{2} =2

A=\pi r^{2} =\pi (2)^{2} =\pi (4)=4\pi

The shaded area:

9\pi -4\pi =5\pi

Hope this helps

Which graph represents the solution set of the system of inequalities
seraphim [82]
The solution of a linear inequality is the ordered pair that is a solution to all inequalities in the system and the graph of the linear inequality is the graph of all solutions of the system. Graph one line at the time in the same coordinate plane and shade the half-plane that satisfies the inequality.
