Equation for 14+ W= 26

OLEGan [10]

Answer: w = 12

Step-by-step explanation: In this problem, we want to get w by itself on one side of the equation. Since we have 14 + W, in order to get w by itself, we must subtract 14 from the left side of the equation.

If we subtract 14 from the left side of the equation, we must also subtract 14 from the right side of the equation. So on the left, +14 and -14 cancel each other and on the right, 26 - 14 simplifies to 12 so w = 12.

To check our answer, we substitute a 12 back in for w in the original equation and we have 14 + (12) = 26 or 26 = 26 which is a true statement so the answer checks.

I need to know the answer so I can correct it so I can fully retake my test

torisob [31]

Answer:

D. all real numbers

Step-by-step explanation:

4(x+3)-7greater than or equal to x+3(x+1)

4x+12-7> or equal to x+3x+3

4x+5>or equal to 4x+3

so, by testing

if x=1, is it true that 4x+5 is greater than or equal to 4x+3

4(1)+5=4(1)+3

9=7

hence it true 9 is greater than 7

Option D is collect

Drawing a red marble from a bag of six red and 4 blue replacing it and then drawing a blue marble

Ksivusya [100]

Answer:

The probability of picking a red marble and a blue marble = 6/25

Step-by-step explanation:

Here, the question is INCOMPLETE.

What is the probability of this independent event. Drawing a red marble from a bag of 6 red and 4 blue marbles, replacing it, and then drawing a blue marble.

Here, total number of red marble in bag = 6

total number of blue marble in bag = 4

So, total marbles in the bag = 6 + 4 = 10 marbles

Now,if E : Any given event, then

$\textrm{P (Event E)} = \frac{\textrm{Total number of favorable outcomes}}{\textrm{Total Outcomes}}$

So, here $\textrm{P (Picking a Red marble)} = \frac{\textrm{Total number of red marble}}{\textrm{Total marble}} = \frac{6}{10} = \frac{3}{5}$

⇒ P(a Red ball) = 3/5 ...... (1)

Now, if the picked marble is REPLACED, then total marbles in the bag = 10

So, here $\textrm{P (a Blue marble)} = \frac{\textrm{Total number of blue marble}}{\textrm{Total marble}} = \frac{4}{10} = \frac{2}{5}$

⇒ P(a Blue marble) = 2/5 ...... (2)

So, the probability of picking a red marble and a blue marble AFTER REPLACING

=P(a Red marble) x P(a Blue marble) = 3/5 x 2/5 = 6 /25

Hence, the probability of picking a red marble and a blue marble = 6/25

If n^3=x and n^4=20x , where n>0, what is the value of x?

Natali5045456 [20]

Step-by-step explanation:

∠2 and ∠7 are alternate exterior angles so they are equal.

So you can create the equation

40x-48 = 20x+52 Subtract 20x from both sides. Add 48 to both sides.

20x = 100

x = 5

if you need m∠2 Substtute 5 for x in 20x+52

20(5) + 52 = 100 +52 m∠2= 152°

m∠7 40(5) - 48 = 200-48 m∠7= 152°
