Factor each expression 77x+21

Answers

Answer 1

Answer: 77x + 21

We need to find the common factor between the coefficient and the constant.

77 ÷ 7 = 11
21 ÷ 7 = 3

7(11x + 3) is the factor of 77x + 21.

7(11x + 3) can be expanded using the distributive property of multiplication.

7(11x) + 7(3) = 77x + 21

Round 354,605 to nearest thousand

Answers

Answer

355,000.

Explanation

When rounding numbers we count digits from the right to the left. The first place value from the right is once followed by tens, hundreds, thousands etc.

354,605

5 ⇒ ones

0 ⇒ tens

6 ⇒ hundreds

4 ⇒ thousands

354,605 to the nearest thousands is 355,000.

Answer:

$355,000$

Step-by-step explanation:

We have been given an number $354,605$ . We are asked to round our given number to the nearest thousand.

Upon looking at our given number we can see that the value of the 1st dropped figure that is at hundreds place value, is greater than 5.

Since hundreds place value is 6 or we can see that last three digits are 605, therefore, we will round up our number to nearest thousand as:

$354,605\approx 355,000$

75 students decreased by 80%. Help plz:///

Answers

So,

75 students decreased by 80%. That means that 100 - 80 = 20% remain.

To find 20% of 75 students, just find 10%, which means simply moving the decimal point one place to the left.

75 --> 7.5 = 10% of 75

Therefore,
15 = 20% = 75 because 7.5 * 2 = 15

There are 15 students left.

Terribly sorry if i am wrong.. I believe it would be about 40%
