Answer: The length of a side of the square is given by x
The length of a side of the equilateral triangle is given by x=1
Given is : The perimeter of a square is equal to the perimeter of an equilateral triangle.
Perimeter of square is given as 4 x side.
Perimeter of equilateral triangle is given as 3 x side.
So, we will make both equal.
As x = 1 for triangle, the equation becomes:
4x=3
so x=3/4

Write each number as a multiple of 1/3.

Y=
Answers
Answer:
The answer is y = -15x + 35.
Step-by-step explanation:
We want to isolate y, so we cancel everything on that side of the equals except y. We begin with the term farthest away from y, which would be 3x. Since it is positive, to cancel it we will subtract. This will give us 1/5y = 7-3x.
Next we want to cancel the 1/5. Since it is directly beside y, this means it has been multiplied; to cancel, we will divide. Divide both sides by 1/5, and we have y = (7-3x)÷(1/5). When we divide fractions, we flip the second one and multiply; this means we have y=(7-3x)*5.
Using the distributive property, we have y=7*5-3x*5, which gives us y=35-15x. We can write this as y=-15x+35.
Answer:
y = 35 - 15x
Step-by-step explanation:
Given
3x + [tex]\frac{1}{5}[/tex] y = 7 ( subtract 3x from both sides )
[tex]\frac{1}{5}[/tex] y = 7 - 3x ( multiply both sides by 5 to clear the fraction )
y = 5(7 - 3x) , that is
y = 35 - 15x

1) The price of a dress is $89. Susan has a coupon for $50 off ger entire purchase and another coupon for 50% off one item. The store's policy does not allow for both coupons to be used at once. Which monetary incentive would give Susan a better buy. $50 off coupon is a better buy 50 of one item is a better buy.
Answers
First coupon:
89 - 50 = $39 (discount price)
Second coupon:
50% = 0.5
89 * 0.5 = 44.5
89 - 44.5 = $44.5 (discount price)
39 < 44.5
Therefore, the better option is using the $50 off one item.

Complete Question
Students in a pre-algebra class are given the polynomial 12x²y - 6xy +18y² and told to factor out the greatest common factor.
Which student has made the correct choice? (1 point)
a) Delia chose 3y because she said that it was a factor of every term.
b) Pedro chose y because he said that the greatest common factor can be found only by looking at the variable terms.
c) Mike chose 6y because he said that it was the largest factor of every term. d) Marisol chose 6 because she said that it was the only greatest common factor in each term.
Answer:
c) Mike chose 6y because he said that it was the largest factor of every term.
Step-by-step explanation:
Step 1
Identify the GCF of the coefficients.
12x²y - 6xy + 18y²
Coefficients are :
12, 6, 18
The Greatest Common Factor for 12, 6, 18 =
The factors of 6 are: 1, 2, 3, 6
The factors of 12 are: 1, 2, 3, 4, 6, 12
The factors of 18 are: 1, 2, 3, 6, 9, 18
Then the greatest common factor is 6.
Step 2
Identify the GCF of the variables.
x²y , xy, y²
The GCF of these variables is y
Step 3
Combine to both GCF's to obtain the GCF of the expression.
= 6 × y
= 6y
The Greatest Common Factor for the expression 12x²y−6xy + 18y² is 6y
Step 4
We factorise
= 12x²y−6xy + 18y²
= 6y(2x² - x + 3y)
Therefore, Option c) Mike chose 6y because he said that it was the largest factor of every term is the correct option.
Mike is correct.
13. A new CD costs $13.79, plus $0.97 in sales tax. How much do 3 new CDs cost? Explain how
you found your answer.
Answers
Answer:
the cost of the three new CDs is $44.28
Step-by-step explanation:
Here in this question, we are interested in calculating the cost of 3 new CDs cost.
From the question, we already know the cost of one. The cost of three would be 3 multiplied by the cost of one.
The cost of the three excluding the sales tax = $13.79 * 3 = $41.37
The sales tax for the three pieces = 3 * $0.97 = $2.91
The cost of the three CDs including the sales tax = $41.37 + $2.91 = $44.28

Answers
Answer: 1,000
Step-by-step explanation:
1,750 divided by 1.75 =1,000
Answer:
1,000
Step-by-step explanation:
If the class wants to raise a total of $1,750 and make a profit of $1.75 from each candy bar that gets sold then you take the total and divide it by the amount of profit each bar makes. So you do 1,750 divided by 1.75 and that gives you 1,000. So the class must sell 1,000 candy bars to reach their goal.

The second correct one is -8 because 6-8 is -2 but as I was saying before how the absolute value changes it into positive, that means -2 would be switched to 2 meaning that -8 is also a correct answer.

Answers
Answer:
It will take both faucets 200 minutes to fill a pool with 9,000 liters of water
Step-by-step explanation:
Here, we want to know the time it will take for both faucets to fill a pool with 9,000 liters of water
What we need here is to have a joint rate for both faucets;
For the first faucet, we have a rate of 100 liters per 5 minutes so this means in a minute;
100/5 = 20 liters per minute
For the second faucet, the per minute rate will be 100/4 = 25 liters per minute
So therefore, the joint rate will be;
25 liters per minute + 20 liters per minute = 45 liters per minute
So the time needed to fill 9,000 liters of water in a pool will be ;
9000 liters/ 45 liters per minute = 200 minutes

Answers
The expression for temperature change in City A is 9 + (-8)
The amount the temperature changes for City A = 1°F
The expression for temperature change in City B is -1 + (-3) = -4°F
The amount the temperature changes for City B = -4°F
Calculations and ParametersBased on the available data:
In City A, the temperature rise from 8 am to 9 am = 9°FIn City A, the temperature drop from 9 am to 10 am = 8°FIn City B, the temperature drop from 8 am to 9 am = 1°FIn City B, the temperature drop from 9 am to 10 am = 3°FThe expression for that represents the temperature change from 8 am to 10 am is, therefore;
For City AThe temperature change from 8 am to 10 am are
8 am to 9 am = +9°F9 am to 10 am = -8°FSum, change from 8 am to 10 am = 9 + (-8) = 1°F
For City BThe temperature change from 8 am to 10 am are
8 am to 9 am = -1°F9 am to 10 am = -3°FSum, change from 8 am to 10 am = -1 + (-3) = -4°F

Step-by-step explanation:

Step 2- Multiply
3x-3-8= 4+4x+5
Step 3- Add.
3x-3-8= 4x+9
Step 4- Subtract 3x to both sides to move the variable to one side.
3x-11= 4x+9
-3x -3x
Step 5- Subtract 9 to both sides.
-11= 1x+9
-9 -9
