General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define systems</u>
y = 5x - 3
3x - 2y = 27
<u>Step 2: Rewrite systems</u>
- Define: 3x - 2y = 27
- Add 2y on both sides: 3x = 2y + 27
- Divide 3 on both sides: x = 2/3y + 9
<u>Step 3: Redefine</u>
y = 5x - 3
x = 2/3y + 9
<u>Step 4: Solve for </u><em><u>y</u></em>
- Substitute in <em>x</em>: y = 5(2/3y + 9) - 3
- Distribute 5: y = 10/3y + 45 - 3
- Combine like terms: y = 10/3y + 42
- Subtract 10/3y on both sides: -7/3y = 42
- Divide -7/3 on both sides: y = -18
Answer:
its negative :)
Step-by-step explanation:
..........
So basically, he wants to make mixture where lemon=lime
it is 6 gallons so
40% of 6=0.4 times 60=2.4=lemon
60% of 6=0.6 times 60=3.6=lime
so to make them equal
3.6-2.4=1.2
he must add 1.2 gallons of 100% lemon juice to make a mixture of 50% lemon and 50% lime
1.2 gallons is the answer
The author of Passage 1 indicates that becoming adept at using the Internet can undermine the ability to think deeply.
<h3>
What according to the author, becoming adept at using the Internet can cause?</h3>
Passage 1's author cites Patricia Greenfield's study, which discovered that people's use of screen-based technologies harmed their ability to acquire knowledge, perform "inductive analysis" and "critical thinking," and be imaginative and reflective.
The author of Passage 1 concludes that people's ability to think "deeply" is hampered by their use of screen-based technologies.
Option A, C, and D are incorrect because the author of Passage 1 does not address how people's health, social contacts, or self-confidence are affected by using the Internet.
The author of Passage 1 suggests that becoming proficient with the Internet can impair one's ability to think deeply.
Therefore, the correct answer is option B) undermine the ability to think deeply.

Take the natural log of both sides
ln(2^x)=ln(.125)
Xln(2)=ln(.125)
X=ln(.125)/ln(2)
X=-3
ALTERNATIVE ROUTE:
You know that 0.125 is equal to 1/8
And 1/2^3 is also equal to 1/8
So since you need the reciprocal to match it the exponent is a negative
