Answer:
1. y = −3x + 1
y = 3x + 1
SOLUTION:
The two equations intersect at exactly one point, so
they are consistent and independent.
2. y = 3x + 1
y = x − 3
SOLUTION:
The two equations intersect at exactly one point, so
they are consistent and independent.
3. y = x − 3
y = x + 3
SOLUTION:
These two equations do not intersect, so they are
inconsistent.
4. y = x + 3
x − y = −3
SOLUTION:
Rearrange the f

Answer: 12.9
Step-by-step explanation:
Change each proportion so that it is __ kg = 1 pound and __ stone = 1 pound. Once you do this you should get that 0.45 kg = 1 pound and 0.07 stone = 1 pound. Then, you set up another proportion using these conversions, which would be 0.45 kg over 0.07 stone is equal to 83 kg over x stone. Once you solve for x, you get the answer of 12.9

Answer:
3.3 miles
Step-by-step explanation:
0.5 = 5.6 $
mileage rate = 1 mile for $2
2.5 = $1.6
1.6 / 0.2 = 8
8×0.1 = 0.8
2.5+0.8=0

Dillon decided to construct a rectangular deck in his back yard. It is 16 feet long and 13 feet wide. He is trying to determine whether he should construct the deck using cedar or a pressure treated material.
The cedar costs $21.09 per square foot for materials.
The pressure treated material costs $18.90 per square foot for materials.
The cost for labor will be the same for either material.
How much money would Dillon save installing a deck with pressure treated material instead of cedar? Explain or show your reasoning. You may use diagrams, drawings, or equations as well as words.

It takes Kevin 15 minutes to drive 5 1/2 miles.
How many miles does Kevin drive per minute?
a) 11/30
b) 5/6
c)2 8/11
d) 3
Answer: 11/30 miles per minute
Step-by-step explanation:
To get miles per minute
Divide the distance by the time
5 1/2 ÷ 15 . Change 5 1/2 to an improper fraction 11/2
invert the divisor and multiply: (Multiply by the reciprocal of 15: 1/15)
11/2 × 1/15 = 11/30
Here, we are required to determine how many miles does Kevin drive per minute.
The number of miles Kevin drives per minute is 0.3667miles.According to the question, Kevin drives 5 1/2 miles (5.5 miles) in 15 minutes.
To determine how many miles Kevin drives per minute, we need to determine Kevin's speed over the 15 minutes in which he covered 5.5 miles.
Speed = distance/timeSpeed = 5.5miles/15minutes
Therefore, Speed = 0.3667 miles per minute.
Ultimately, Kevin drives 0.3667miles per minute.

A small, test batch of lemonade used 1/4 cup of sugar added to 1 cup of water and 1/4 cup of lemon juice. After confirming it tasted good, a larger batch is going to be made with the same ratios using 10 cups of water. How much sugar should be added so that the large batch tastes the same as the test batch?
Hint: there is extra information in this.
Answer:
2 1/2 cups of sugar
Step-by-step explanation:
Answer:
2.5 or cups of sugar
Step-by-step explanation:
Since the problem multiplied the water by ten, to keep the ratio even we multiply everything else by ten. 1/4*10= 2.5 We do not need the information about the lemon juice since we are trying to figure out the amount of sugar.

Hello!
When there are 2 variables that are the same (in this case y), you add the exponents! In this case, we have [tex]y^{5}[/tex] and [tex]y^{14}[/tex] , and since 5 and 14 are the exponents, we add them! 5+14 is 19, so the answer is [tex]y^{19}[/tex]!

-2/5 + 4/3
Show work.
Answer:
14/15
Step-by-step explanation:
Find common denominators. Note that what you do to the denominator, you do to the numerator.
Use 15 as the common denominator:
(-2/5)(3/3) = (-6/15)
(4/3)(5/5) = (20/15)
Combine like terms:
-6/15 + 20/15 = (20 - 6)/15 = 14/15
14/15 is your answer.

Answer:
[tex]\frac{14}{15}[/tex]

The original quantity is 20 and the new quantity is 15. Adam incorrectly says the percent decrease is about 14.29%. What is the correct percent decrease? What error did Adam likely make when finding the percent decrease? The correct percent decrease is 25 25%. What error did Adam likely make? A. divided the difference of the two quantities by the sum of the two quantities. B. divided the difference of the two quantities by the product of the two quantities. C. divided the difference of the two quantities by the new quantity. D. divided the new quantity by the original quantity.
Answer: A. divided the difference of the two quantities by the sum of the two quantities.
===================================================
Explanation:
The difference of the quantities is 20-15 = 5
The sum of the quantities is 20+15 = 35
Dividing those results leads to 5/35 = 0.142857 which rounds to 0.1429
That converts to 14.29%
This is likely the path Adam took. This path is incorrect. The correct steps are shown below
---------------------
Difference = 20-15 = 5
Divide the difference over the original quantity
5/20 = 1/4 = 0.25 = 25%
We have a 25% decrease because the new quantity (15) is smaller than the old quantity (20)
----------------------
Here's another way to approach the problem
A = old value = 20
B = new value = 15
C = percent change
C = [ (B-A)/A ] * 100%
C = [ (15-20)/20 ] * 100%
C = (-5/20)*100%
C = -0.25*100%
C = -25%
The negative C value means we have a negative percent change, ie we have a percent decrease. So this is another way to get a 25% decrease.
