John needs to write 2,146 online math questions in 45 weeks. John is estimating how many
questions he should write each week to meet the deadline. Which compatible numbers provide a better
estimate for the number of question he should write each week, 2,000 ÷ 50 or 2,000 ÷ 40? Why?
A 2,000 ÷ 50 is a better estimate because 50 weeks is more than the amount of time he actually has.
B 2,000 ÷ 50 is a better estimate because 2,000 is less than the amount of questions he actually needs to write.
C 2,000 ÷ 40 is a better estimate because 2,000 is less than the amount of questions he actually needs to write.
D 2,000 ÷ 40 is a better estimate because 40 weeks is less than the amount of time he actually has.
Answer:
Answer: 2,000 ÷ 50
Reason:
From the question, we are informed that John needs to write 2,146 online math questions in 45 weeks and that he is estimating how many questions he should write each week to meet the deadline.
The compatible numbers that provide a better estimate for the number of question he should write each week, is 2,000 ÷ 50. This is because rounding up of 2146 to the nearest thousand gives 2000. The number beside the thousand place is 2 and sinces it's not up to 5, the number becomes 2000. Likewise 45 to the nearest ten gives 50 since the number beside the ten is 5, therefore 1 will be added to 4 which becomes 5 and the number in the unit place is changed to 0, this makes the number become 50.
Therefore, the answer is 2000 ÷ 50.

Vicci designed a square tile in art class. Each corner of the square tile has a measure of 90 degrees.
Which equation could be used to find the measure of Angle x?
Answer:
360-270=x
x=90 degrees
Step-by-step explanation:
There are two ways i know of how you can do this
The first way:
Ok so lets add up all the angles we know
90+90+90=270
Now we subtract that from 360
360-270=90
And there we have it the measure of angle x is 90 degrees
The second way:
Ok lets name all the angles we know. Hypothetically we only know that one angle is 90.
measure of angle one is 90 degrees
So now we subtract that from 360
360-90=270
Now we divide that by three because there are only 4 angles and we know the measure of one of the angles
270/3=90
And there we have it the measure of angle x is 90 degrees
Bruno bought 96 pounds of sugar for his bakery. Every day he used the same amount of sugar to make bakery items. After 10 days, Bruno was left with 15.2 pounds of sugar. On average, how many pounds of sugar did Bruno use each day? (1 point)
a 5.60 pounds b 8.08 pounds c 11.12 pounds d 18.46 pounds
Answer:
9.6
Step-by-step explanation:
you divide 96 by 10
Answer:
The answer is B
Step-by-step explanation:
The answer is B. Since Bruna used 96 pounds of sugar each day you would have to use the equation 96-x(10 times)=15.2. You would have to plug in each answer to see if it would give you 15.2. I plugged in 5.60 and Bruno was left with too many pounds left over. 11.2 pounds each day would be to low. I then plugged in 8.08 and subtracted by 96 ten times and got the answer 15.2. I hope this helps.
solve the equation using mental math n divide 9=9
Answer:
81
Step-by-step explanation:
When dividing these numbers, you would actually multiply them together because they are on different sides of the equals sign. You do this because whatever you do on one side, you'd do the opposite of to the other side.
Example:
2x + 3 = 9
You would subtract 3 from nine.
2x = 6
The you'd divide 6 by two, since you would multiply x by two.
x = 3

55+(-72)-(-45)=x
what is x?
Answer: x=28
Step-by-step explanation:
55−72−(−45)=x
Step 1: Simplify both sides of the equation.
55−72−(−45)=x
55+−72+45=x
(55+−72+45)=x(Combine Like Terms)
28=x
28=x
Step 2: Flip the equation.
x=28
the rectangular projection screen in the school auditorium is 5 times as long and 5 times as wide as the rectangular screen in the library. the screen in the library is 4 feet long with a perimeter of 14 feet.
what is the perimeter of the screen in the auditorium?
Answer:
Library: length 4, width 3 = 4(2)+3(2)=14
Take the length and width and multiply them by 5.
4*5=20 and 3*5=15
20(2)+15(2)= 70
The perimeter of the auditorium screen is 70.

I need the Answer ASAP. Sally wants to make a costume that has 2 different color fabrics. The yellow fabric is 3 yards long and is used on 65% of the final dress. How long is the pink fabric?
Answer:
1.62 yards
Step-by-step explanation:
[tex]\frac{65}{3} =21.666666[/tex]
[tex]\frac{100}{21.6} = roughly 4.62[/tex]
This means that there are 4.62 yards in the final product.
The pink fabric is [tex]4.62-3=1.62[/tex] yards.

On the first one I know it is not Noah so please don´t put Noah. Also make sure to explain please
Step-by-step explanation:
For the question 5, Noah is right, as 75/100 x 10 = 7.5, and 25/100 x 30 = 7.5
So both of then have equal amount, therefore, Noah is right.

Examine the equation.
–3x + 18 = 7x
What could you do to isolate the variable term to one side of the equation?
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
[tex] - 3x + 18 = 7x[/tex]
[tex]7x = - 3x + 18[/tex]
Add sides 3x
[tex] + 3x + 7x = + 3x - 3x + 18[/tex]
[tex]10x = 18[/tex]
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
Answer:
10x + 18
You cancel out the lowest variable term to only have one variable term.
Step-by-step explanation:
-3x+3 then do 7x+3
10x + 18
You cancel out the lowest variable term to only have one variable term.
