Answer:

Step-by-step explanation:

Plug in the values for x and y into the expression and simplify:

numerator: 4(2) + 4 = 12

denominator: 2(4) - 2 = 6

dividing: 12/6=2

Answer: 2

If x is 2 and y is 4 we have

4(2) + 4 / 2(4) - 2

4 x 2 is 8

8 + 4 is 12

Now we have

12/ 2(4) - 2

2 x 4 is 8

8 - 2 is 6

So now we have

12/6 which can be simplified to 2

Solve for x and y: x+y=c x-y=a

Lunna [17]

Answer:

x = (c+a)/2

y = (c-a)/2

Step-by-step explanation:

x+y=c

x-y=a

Add together to eliminate y

x+y=c

x-y=a

--------------

2x = c+a

Divide by 2

2x/2 =(c+a)/2

x = (c+a)/2

Multiply the second equation by -1

-x+y =-a

Add the first equation

x+y =c

-x+y=-a

-----------------

2y = c-a

Divide by 2

2y/2= (c-a)/2

y = (c-a)/2

You draw two marbles from a bag containing 3 blue marbles,2 green marbles and 5 red marbles without replacement. what is the pro

lina2011 [118]

The probability of drawing a red marble then a green marble would be 1/9.
In the first draw, there is a total of 10 marbles to choose from, and choosing a red marbles' probability would be 5/10, or 1/2. However in the second draw, there are only 9 marbles to choose from since you have already taken out a marble. Choosing a green marble in the second draw's probability would be 2/9. Using the rule P(A and B) = P(A) • P(B), we can also apply it to this problem "P(choosing a red marble first and then choosing a green marble second)" = 1/2 • 2/9, which is equal to 2/18. If you simplify that, you get 1/9.

178.98 = 6(0.04m + 24.90 + 0.10(24.90))

Alexeev081 [22]

Let's solve your equation step-by-step.
178.98
=
6
(
0.04
m
+
24.9
+
(
0.1
)
(
24.9
)
)
Step 1: Simplify both sides of the equation.
178.98
=
6
(
0.04
m
+
24.9
+
(
0.1
)
(
24.9
)
)
178.98
=

178.98
=
(

)
+
(
149.4

(Combine Like Terms)
178.98
=
0.24
m
+
164.34
178.98
=
0.24
m
+
164.34
Step 2: Flip the equation.
0.24
m
+
164.34
=
178.98
Step 3: Subtract 164.34 from both sides.
0.24
m
+
164.34
−
164.34
=
178.98
−
164.34
0.24
m
=
14.64
Step 4: Divide both sides by 0.24.
0.24
m
0.24
=
14.64
0.24
m
=

Answer:
m
=
61

If the median of the score distribution on this pop quiz is more than 170, the teacher will drop the next pop quiz. The pop quiz

kirill [66]

In obtaining the median of the data set we have to arrange the data from the lowest to the highest in the pop quiz

110, 125, 138, 144, 152, 153, 162, 163, 164, 174, 174, 175, 177, 180, 183, 185, 186, 187, 194, 195, 196, 198.

After arranging it, locate the number that is situated in the middle. Since the number of data is even(22) , check the data that is in between the 11th and 12th number, which is 174 and 175, the answer would be 174.5.
