Solve for w. 0.05w = 15

2 answers:

6 0

To solve for w, we need to get w by itself.
Since w is being multiplied by 0.05, we need to reverse that. The opposite of multiplication is division.
Divide 0.05w and 15 by 0.05.
15/0.05 = 300.
w = 300. Hope this helps!

In order to find the value first multiply both sides by 100 to simplify the equation:
0.05w*100=15*100
5w=1500
Next, divide both sides of the equation by 5:
5w/5=1500/5
w=300
The final solution is w=300!

Hope i could help.
have a great day

5.3.4 Journal: Two-Variable Systems Elimination I need urgent help

max2010maxim [7]

Answer:

1) X stands for individual acts and y, group acts. 2) Each scenario describes a different period in minutes, but each one respecting their different amounts (individual and group acts). 3) $S=\left \{ 5,10 \right \}$

Step-by-step explanation:

Completing with what was found:

1) Here is a summary of the scenario your classmate presented for the talent show:Main show The main show will last two hours and will include twelve individual acts and six group acts.Final show The final show will last 30 minutes and will include the top four individual acts and the top group act.The equations he came up with are: 12x+ 6y= 120, 4x+ y= 30

1. What do x and y represent in this situation?

X stands for individual acts and y, group acts.

Besides that, In the system of equation, they represent the time for x, and the time for y.

2. Do you agree that your classmate set up the equations correctly? Explain why or why not.

Yes, that's right. Each scenario describes a different period in minutes, but each one respecting their different amounts (individual and group acts). Either for 120 minutes or 30 minutes length. And their sum totalizing the whole period.

3. Solving the system by Elimination

$\left\{\begin{matrix}12x+ 6y= 120\\ 4x+ y= 30\end{matrix}\right.\\\left\{\begin{matrix}12x+ 6y= 120\\ 4x+ y= 30\:*(-3)\end{matrix}\right.\\\left\{\begin{matrix}12x+ 6y= 120\\ -12x+ -3y= -90\end{matrix}\right.\\3y=30\Rightarrow y=10\\4x+(10)=30\Rightarrow 4x=20\Rightarrow x=5\\S=\left \{ 5,10 \right \}$

X - 2y = -3 2x + y = -1

bezimeni [28]

Answer:

y = 1

x = -1

Step-by-step explanation:

x - 2y = -3, then x = 2y - 3

2x + y = -1

substitute for x:

2(2y - 3) + y = -1

4y - 6 + y = -1

5y = 5

y = 1

x = 2 - 3 = -1

Ricardo spends 8/9 hr. reading the paper. He spends 1/4 of the time reading world news and splits the remaining time equally bet

lapo4ka [179]

Total time spent reading is = 8/9 hour

He spends 1/4 of the time reading world news. That is = 1/4 * 8/9 = 2/9 hour

Splits the remaining time equally. Remaining time = 8/9 - 2/9 = 6/9

Splitting it equally = 6/9 divided by 2 = 6/9 * 1/2 = 3/9 = 1/3

Time spent reading comic is = 1/3 hour

I hope this helps.
