Answer:

12 11/35

Step-by-step explanation:

Given Data

First term= 15 3/5

To simple fracrion= 78/5

Second term= 3 2/7

To simple fracrion= 23/7

Hence the operation goes thus

= 78/5- 23/7

LCM = 35

=546-115/35

=431/35

=12 11/35

Answer:

[tex] 12 \frac{11}{35} = \frac{431}{35} [/tex]

Step-by-step explanation:

[tex]15 \frac{3}{5} - 3 \frac{2}{7} \\ (15 - 3) + ( \frac{3}{5} - \frac{2}{7} ) \\ 12 + ( \frac{3}{5} - \frac{2}{7} ) \\ 12 + \frac{11}{35} [/tex]

[tex] \boxed{Answer:{\boxed{\green{= 12 \frac{11}{35} = \frac{431}{35}}}}} [/tex]

x is equals to 4 and y is equal to 1

Step-by-step explanation:

3x+3y=9

x-3y=7

elimination method has to do with eliminating one variable from the question to eliminate y we have to add the equations together which is 4x=16

X=4

substitute x is equal to 4 into any equation of your choice let's use equation 1

E

3(4)+3y=9

12+3y=9

12-9=3y

3=3y

divide both sides by 3 therefore y is equal to 1.

Answer:

45 degrees

Step-by-step explanation:

Sin(x)= 62/88

Sin-¹(62/88)= 44.8 = 45. (The inverse function of sine)

Answer:

a<-4

Step-by-step explanation:

To solve this, you have to isolate a. This means you will have to add 5 to both sides. This will make the equation -2a>8. Divide both sides by 2 to get -a>4. Divide each side by -1 to get a>-4. Because you have to flip the sign when you divide by a negative number, you have to change it into a<-4.

Answer:

x = 74

Step-by-step explanation:

One of the properties of a parallelogram is that opposite angles are congruent. This means that the angle with a measure of (74) degrees and (x) degrees are the same, thus the following conclusion can be drawn,

x = 74

Answer:

The domain (input values) of the sine function is:

O B. all real numbers

The domain of the sine function will be all real number. Then the correct option is B.

The domain means all the possible values of x and the range means all the possible values of y.

Simply put, trigonometric functions also referred to as cyclic capabilities the functions of a triangle's inclination.

Let the sine function be f(x) = sin x.

It is a function that repeats itself in a particular time interval.

The domain of the sine function will be all real number.

And the range of the sine function will be [1, –1].

Then the correct option is B.

The graph of the sine function is given below.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given the expression √-36

This can also be written as;

√36 = √36 * √-1

Since i² = -1

√-1 = i

Substitute into the resuting expression

√-36 = √36 * i

√-36 = 6i

Hence the required answer is 6i

Answer: The answer is i sqrt 36  and  6i

Answer:

3/10

Step-by-step explanation:

First we count the number of beans in total which is 20

Then we count the number of red beans which is 6

6/20 can be simplified to 3/10

Answer:

C) 3/10

Step-by-step explanation:

There are 6 red + 5 blue + 4 green + 5 black = 20 jelly beans in total

Since there are 6 red jelly beans, the probability of randomly selecting a red jelly bean is 6 red jelly beans / 20 total jelly beans = 6/20 = 3/10
