2 1/3 + 3 1/4 as a fraction

Answers

2 1/3 = 7/3
3 1/4 = 13/4
Make like denominators
(7/3)(4/4) = 28/12
(13/4)(3/3) = 39/12
Then add across
67/12 (improper fraction)
in mixed number form: 5 7/12

Answer:

67/12  (just in case if they would ask you for the simplified form the answer in is 5 7/12)

Step-by-step explanation:

convert both mixed fractions to improper fractions first

2 1/3 = 7/3    3 1/4 = 13/4

(cross multiplication method, to make both fractions have the same denominator)

7/3 + 13/4

7/3 × 4/4 = 28/12

13/4 × 3/3 = 39/12

28/12 + 39/12 = 67/12 (just add, denominator will remain the same)

67/12 (simplify)

67/12 = 5 7/12 (simplified)

Darren is training for a triathlon. Each week, he goes to the gym for a maximum of 20 hours. He spends at least 8 of those hours weightlifting (x). He wants to spend no more than 15 hours doing cardio exercises (y). Write a system of linear inequalities that represents the restrictions of this scenario.

Answers

The graph of the equations was plotted using geogebra graphing and attached.

Let x represent the hours weightlifting and y represent the hours doing cardio exercises.

Since he spend a maximum of 20 hours, hence:

x + y ≤ 20   (1)

Also, he spends at least 8 of those hours weightlifting, hence:

x ≥ 8          (2)

He wants to spend no more than 15 hours doing cardio exercises, this is:

y ≤ 15     (3)

What is the 40th term of the arithmetic sequence?

21, 18, 15, 12, 9,...


−96


6


138


−99

Answers

Answer:

We start off with 21 as the first term. So a1 = 21

The common difference is d = -3 because we subtract 3 each time to get from one term to the other (eg: 21 to 18 is minus 3)

The nth term of an arithmetic sequence is found by using this formula

an = a1 + d(n-1)

let's plug in the values we have so far to get

an = 21 + (-3)(n-1)

an = 21 - 3(n-1)

an = 21-3n+3

an = -3n+24

Why do this? Well it's helpful so we can find any term in the formula we want. In this case, we want the 40th term. So just plug in n = 40 from here and you're done

an = -3n+24

a40 = -3*40+24

a40 = -96

pointing you to the answer of choice B) -96

Answers

Answer:

x = 7

Step-by-step explanation:

Rearrange the equation to make x the subject.

Original:

7x + 3 = 52

subtract 3 from both sides

7x = 52 -3

7x = 49

Divide both sides by 7

x = 49/7

x = 7

The probability that a red block is selected from a bucket is
3/8, and the probability that a blue block is selected is 2/8.
What is the probability that a red block or a blue block is
selected?
a) 1
b) 1/2
c) 5/8
d) 6/8

Answers

Answer:

5/8

Step-by-step explanation:

Since we don't know what the other color (s) are, all we need to do to determine the probability is add the two fractions, and that is your probability.

Answer:

5/8

Step-by-step explanation:

The probability of a red block shows 3/8.  This means there are 8 blocks total and only 3 of them are red.

The probability of a blue block shows 2/8.  Again there are 8 total blocks and only 2 are blue.

So the total number of blocks remains the same....8

The total of red and blue blocks is 3 + 2 = 5

So the probability would be 5/8
