Isabel’s class has collected 90 cans in a food drive. They plan to sort the cans into n bags, with an equal number of cans in each bag. Write an expression to show how many cans there will be in each bag.

Answers

Answer:

90/n

Step-by-step explanation:

There are 90 cans, and each bag MUST have an equal amount of cans, so if we had, let's say 2 bags, then there would be 45 bags. We got this by doing 90/2. 2 being n, the expression would be 90/n.

How to solve 3 3/5 - 2/3?

Answers

Conversion a mixed number 3 3/
5
to a improper fraction: 3 3/5 = 3 3/
5
= 3 · 5 + 3/
5
= 15 + 3/
5
= 18/
5


To find new numerator:
a) Multiply the whole number 3 by the denominator 5. Whole number 3 equally 3 * 5/
5
= 15/
5

b) Add the answer from previous step 15 to the numerator 3. New numerator is 15 + 3 = 18
c) Write a previous answer (new numerator 18) over the denominator 5.

Three and three fifths is eighteen fifths
Subtract: 18/
5
- 2/
3
= 18 · 3/
5 · 3
- 2 · 5/
3 · 5
= 54/
15
- 10/
15
= 54 - 10/
15
= 44/
15

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(5, 3) = 15. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 5 × 3 = 15. In the next intermediate step the fraction result cannot be further simplified by canceling.
In words - eighteen fifths minus two thirds = forty-four fifteenths.

The value of the expression 3 ³/₅ - 2/3 in mixed fraction number will be 2 ¹⁴/₁₅.

What is Algebra?

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

The expression is given below.

⇒ 3 ³/₅ - 2/3

Convert the mixed fraction number into a fraction number. Then we have

⇒ 3 ³/₅

⇒ 18 / 5

Then the expression is written as,

⇒ 3 ³/₅ - 2/3

⇒ 18/5 - 2/3

⇒ (18 x 3 - 2 x 5) / 15

⇒ (54 - 10) / 15

⇒ 44 / 15

⇒ 2 ¹⁴/₁₅

The worth of the articulation 3 ³/₅ - 2/3 in the blended part number will be 2 ¹⁴/₁₅.

Answer:

7.396 × 10-5

Step-by-step explanation:

To convert 0.00007396 into scientific notation, follow these steps:

Move the decimal 5 times to right in the number so that the resulting number, m = 7.396, is greater than or equal to 1 but less than 10

Since we moved the decimal to the right the exponent n is negative

n = -5

Write in the scientific notation form, m × 10n

= 7.396 × 10-5

Which equation shows how (-10,8) can be used to write the equation of this line in point-slope from?

Answers

Options :

y – 8 = –0.15(x – 10)

y + 8 = –0.15(x – 10)

y – 8 = –0.2(x + 10)

y + 8 = –0.2(x – 10)

Answer:

y – 8 = –0.2(x + 10)

Step-by-step explanation:

(-10, 8)

General equation in point - slope form:

y - y1 = m(x - x1)

m = slope

Given the points : ( - 10, 8)

x1= - 10 ; y1 = 8

y - y1 = m(x - x1)

Substitute the values of x and y into the equation :

y - 8 = m(x - - 10)

y - 8 = m(x + 10)

The best option which fits is :

y – 8 = –0.2(x + 10)
