Answer:
16y - 4
Step-by-step explanation:
4y(4y - 4) - 4(- 4 + 5 + 4y^2)
16y - 16y - 4(1 + 4y^2)
16y - 16y - 4(4y^2 + 1)
16y^2 - 16y^2 + 4
16y - 4

Answer:y= 4x-2 and y-2=4(x-1)
Step-by-step explanation:
Answer:The answer in y=4x-2
Step-by-step explanation:
So, 4 is how man units it goes up at a time, -2 is the y intercept where it intercepts the Y axis and x is x Here is how to solve the first ordered pair the equation is 4(-1) -2 so 4 times -1 is -4 -2 so basically it is -4 +-2 so you get -6 so to solve the rest do what i just demonstrated just change x to 0,1,2 ect.

Two half gallon containers can hold 1 gallon, whic is about 3.785 liters.
Step-by-step explanation
Answer:
Two half gallon containers can hold 1 gallon( 3.785 liters.)
Step-by-step explanation:
Suppose you go out to eat with a friend and your bill was $25.67. The local sales tax rate is 7% and you want to leave a 20% tip for the waitress. Calculate the 20% tip of $25.67. [tip]
( I need the tip)
Answer:
Umm I'm not sure is it 25...
Step-by-step explanation:
Answer:
Tip= $5.13
Step-by-step explanation:
You can crossmultiply and use the "Is/Of x %/100" method
= X/$25.67 x 20%/100
Cross multiply:
25.67 x 20 = 513.4
Xx100= 100X
To solve for X from here, divide both answers by 100
513.4/100= 5.13
100X/ 100 = X
So...
$5.13 = X
A farmer says that for every row of tomato seeds he plants, he can harvest 6.5 bushels of tomatoes. The farmer needs to harvest at least 52 bushels of tomatoes. What is the least number of rows of tomato seeds that the farmer will need to plant?
Answer:
8 rows
Step-by-step explanation:
The answer is 8 because 52 divided by 6.5 is 8
The least number of rows of tomato seeds that the farmer needs to plant is 8 row.
Given that, a farmer says that for every row of tomato seeds he plants, he can harvest 6.5 bushels of tomatoes.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
The farmer needs to harvest at least 52 bushels of tomatoes.
The number of rows of tomato seeds need to plant = 52/6.5
= 8
Therefore, the least number of rows of tomato seeds that the farmer needs to plant is 8 row.

Which expression is equivalent to -0.2 - 4.9?
A. -4.9 + 0.2
B. -0.2 + (-4.9)
C. 0.2 - (-4.9)
D. -0.2 + 4.9
9514 1404 393
Answer:
B. -0.2 + (-4.9)
Step-by-step explanation:
Subtracting a number is the same as adding its opposite. Subtracting 4.9 is the same as adding -4.9.
The appropriate choice is ...
-0.2 + (-4.9)
Consider the following situation:
Sweet Springs Candy Shop sold 2 pounds of chocolates for $9.98 and 5 pounds of chocolate for $24.95.
A. Is the relationship between the number of pounds of chocolate and the total cost proportional?
B. Why or why not?
Answer:
Yes, they are proportional.
Step-by-step explanation:
If we round it up we can assume that 2 chocolates = $10
which mean each one is about $5
5x5=25 the number stays the same and the price does not change making it proportional.
What do you call the two numbers, when multiplied together, results in the product of 1?
Answer:
1x1
Step-by-step explanation:
Commutative property of multiplication: when two numbers are multiplied together, the product is the same regardless of the order of the factors. Identity property of multiplication: when a number is multiplied by 1 the result is the number itself.

Merry Christmas!
Mary and Julie both have a goal of raising $1000 for
charity. Mary raises $12 every 4 days. Julie raises $19
every 6 days.
Will Mary or Julie reach her goal first? Explain.
This is the sample response… Mary would have a rise of 12 and a run of 4, making her slope, or rate of change, $3 a day. Julie would have a rise of 19 and a slope of 6, making her slope, or rate of change, $3.17 a day. Since Julie is raising money at a faster rate, she would get to the goal of $1000 first.
This is the info that you should include in your response… Mary has a rise of 12 and a run of 4. Mary has a slope of 3. Julie has a rise of 19 and a run of 6. Julie has a slope of 19/6 or 3 and 1/6. Julie will reach her goal first, as she has the greater slope.
Use this information at your advantage.
Hope this helps! :))
Answer:
Julie will reach her goal first because she raises $19 every 6 days so she is working 6 days out of one week. So she will get to her goal first.

URGENT BRAINLEIST CHANCEWhich of the following expressions cannot be written as an integer?
-3 0
18/3
1.2 × 10 -2
√49
Answer:
1.2*10^-2
Step-by-step explanation:
-3^0 is 1, because anything to the power of 0 (except for 0) is always equal to 1. 1 is an integer, so this is not the answer.
18/3=6, and 6 is an integer, so this is not the answer either.
1.2*10^-2 = 1.2*0.01 = 0.012, which is not an integer, so this is the answer.
49 is an integer, so this is not the answer:
Therefore, the answer to this problem is 1.2*10^-2
Hope this helped!
Answer:
[tex]1.2*(10-2)[/tex] cannot be written as an integer.
Explanation:
Fractions and decimals are not integers. All whole numbers and natural numbers are integers.
You can immediately identify that [tex]1.2*(10-2)[/tex] cannot be written as an integer because the decimal is 1.2 and the only way it could become an integer is if it was multiplied by a number ending in 5 or with 5 as a factor (5,1 0, 15, 20, and so on). Also, it has a decimal point that isn't being multiplied by another decimal/fraction. In some cases, decimals or fractions multiplied by each other can equal an integer, but it's that's not the case in this instance.
However, if you couldn't identify this or you needed to check you answer, you could solve the expressions:
[tex]1.2*(10-2)\\1.2*(8)\\9.6[/tex]
9.6 is a decimal, therefore it is not an integer.
[tex]-3 + 0 = -3\\-3*0= 0[/tex]
I don't know if you were attempting to add or multiply, but in both cases, the sum and product equal an integer.
[tex]\frac{18}{3} = 6[/tex]
18 is divisible by 3, so you can assume that the quotient will be an integer. (3*6 = 18, to check your answer)
(To know if something is divisible by three, add the numbers of the dividend. If they equal a number that can be divided by three, you can assume that you'll get an integer and whole number.
For example: 1 + 8 = 9, 3*3 = 9)
[tex]\sqrt{49} =7[/tex]
The square root of 49 is 7. If you've memorized your square roots, you could identify quickly that the square root would be an integer. If you haven't it's okay, keep working on it!
I hope this helps!

Step-by-step explanation: too lazy to write it out.... 0-0
Can someone help me, please. :(
Answer:
The answer is C.
Step-by-step explanation:
It cannot be between 3 and 4 because 2/3 is less than 1. You cannot end up with a larger number than 3 in this case. Similarly, it cannot be less than 2/3 because you are multiplying it by 3, which is larger than your first number.
Therefore, it has to be between 3 and 2/3 because you are taking two thirds of 3, which is 2.

Clare is painting some doors that are all the same size. She used 2 liters of paint to cover 1 3/5 doors. How many liters of paint are needed for 1 door? Draw a diagram to represent the situation, then find the answer.
Answer: 6
Step-by-step explanation: i know this it's hard to explain
It will take 1 3/4 gallons to paint the whole fence.
How can we interpret the division?When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get. Division can be interpreted as equally dividing the number that is being divided into total x parts, where x is the number of parts the given number is divided.
We need to find the expression of 3/4 divided by 1/8
3/4 x 8= 6
Therefore, The value of 7.89 divided by 2 is; 3.945
Now consider the gallons to paint the whole fence be x
1 1/4/x = 5/7
1.25/x = 5/7
then Cross multiply;
(5 × x) = (1.25 × 7)
5x = 8.75
x = 8.75/5
x = 1.75 = 1 3/4 gallons
