Help, Missing work!!!
Answer:
Step-by-step explanation:
11) add 20 to both sides, x=-3
12) divide both sides by -8, v=18
13) divide both sides by -7, n=19
14) multiply both sides by 9, n=171
Answer:
11. x= -3
12. v=8
13. n=19
14. n=171
Step-by-step explanation:
11. 20+3=23, but since the answer is negative, the 3 has to be negative (different signs = negative)
12. 144/8 = 8, since product is negative, the answer has to be positive (different signs = negative)
13. 133/7= 19, answer must be positive because product is negative (different signs= negative)
14. 9*19=171, so therefore 171/9=19

Explain please!!
Answer:
7 7/8
Step-by-step explanation:
add the whole numbers 5+2 which is 7.
now add 3/8 to a 1/2. you need to have a common denominator for both so multiply 1/2 by 4. this would be 4/8. 4/8 plus 3/8 is 7/8.
put the numbers back together to get 7 7/8

The required proportional amount of water is 15 gallons. Option B is correct.
What is proportionality?proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.
Here,
Let the amount of water be x and the amount of bleach be y,
According to the question,
y =kx,
And we have given k = 1/3
y = x/3
Now, put y = 5,
5 = x/3
x = 5×3
x = 15 gallons
Thus, the required proportional amount of water is 15 gallons. Option B is correct.

B: Positive and Negative ions build up and need to discharge
C: High pressure storms condense air into a high energy state
D: Thunderstorms pull energy up from earth to sustain themselves
b Is your answer
Lightning is an electrical discharge caused by imbalances between storm clouds and the ground, or within the clouds themselves. Most lightning occurs within the clouds. ... This heat causes surrounding air to rapidly expand and vibrate, which creates the pealing thunder we hear a short time after seeing a lightning flash

Using a system of elimination is easy:
Bring the two equations up.
[tex]-6x + 9y = -12\\8x - 9y = -8\\[/tex]
Since we have 9y and -9y, they cancel each other out.
We now have:
[tex]-6x = -12\\8x = -8\\[/tex]
Now solve for x.
1. x = 2
2. x = -1.
