Answer 1

Answer:

45/8 or 5 5/8

Step-by-step explanation:

2 1/4. 2 times 4 is 8 plus 1 is 9 (9 over 4 (9/4)). 2 1/2. 2 times 2 is 4 plus one is 5. (5 over 8 (5/2)). 9/4 x 5/2. 9 times 5 is 45, 4 times 2 is 8.  you get the improper fraction 45/8. 45 simplified is 5 5/8. hope i helped.

Answer 2

Answer:

45/8 or 5 5/8

Step-by-step explanation:

When multiplying fractions, it ALWAYS so much easier to make them into improper fractions (for me at least). When doing this, multiply the denominator to the whole number and add the numerator and keep the denominator the same. So, for 2 1/4, you could use the equation 2(4) + 1 = x/4. You should get 9/4. Doing this for the other mixed fraction, you get 5/2.

Multiplying fractions is pretty straightforward after that. You don't have to change the denominators to match each other like you do when adding, instead you just multiply straight across. Multiply both of the numerators and then the denominators.

                                      Numerators: 9 x 5 = 45

                                      Denominators: 4 x 2 = 8

So, you get 45/8. If you're wanting a mixed number fraction, just divide 45 by 8. 8 goes into 40 5 times, and you get a left over number 5. Therefore, as a mixed fraction you get 5 5/8.

I don't know how you wanted me to show my work, but I tried the best I could to explain.

You pay 3.5% annual simple interest for 12 years on a loan, and you pay $1,512 in interest. How much is the principal?

Answers

A = Pe^rt
Amount of interest paid = Principal*e^ (rate*time)
(The rate must be in decimal form)
3.15% / 100 = .0315

1,512 = P[e^(.0315*12)]
1,512 / e^(.0315*12) = P
1036.06 = P
$1036.06 was the Principal

Answers

Answer:

x = 2.5

y = 5

Step-by-step explanation:

2x + 3y = 20

2x + y = 10 then y = 10 - 2x

substitute for y:

2x + 3(10 - 2x) = 20

2x + 30 - 6x = 20

reduce:

-4x = -10

divide both sides by -4:

x = 2.5

y = 10 - 2(2.5) = 5

check:

2(2.5) + 3(5) = 20

20 = 20

and

2(2.5) + 5 = 10

10 = 10

two numbers have ratio 12:5.their differnce is 49.find the two numbers .​

Answers

Answer:

84 and 35

Step-by-step explanation:

12 - 5 = 7

12(7) = 84

5(7) = 35

Two numbers: 84 and 35

Step-by-step explanation:

Let the two numbers be x and y

Given:

Ratio of two numbers= 12:5

Difference between two numbers= 49

So, we need to find the difference between its ratio in order to get two numbers.

12 - 5 = 7

Thus, simply on multiplying the number so obtained after subtraction we will get:  

12 * (7) = 84

5 * (7) = 35

Also, the difference is given which is 49

so, we can confirm it by finding the difference between the numbers obtained which is 84-35=49

Therefore, the two numbers are 84 and 35.

​ y=3x+3 y=−2x+3 ​ how many solutions does the system have

Answers

Answer: One solution

Step-by-step explanation:

y = 3x + 3

y = -2x + 3

-----------------------------------------------------------------------------------------------------------

To solve this, you need to understand a few things:

a) If two lines have the same slope but different y-intercepts, they are parallel when graphed and thus do not have any solutions

b) If two lines have the same slope and same y-intercepts, they are the same line when graphed and thus do not have infinitely many solutions

c) If two lines have different slopes (and/or y-intercepts), they have one solution

-----------------------------------------------------------------------------------------------------------

These two lines have different slopes but the same y-intercept (condition c)

So they have one solution
