30-10x and 10(3-x) equivalent or not?

Answers

Answer:

no

Step-by-step explanation: You can use variables to find that out. PEMDAS works too (parenthesis, exponents, multiplication, division, addition, subtraction). Put a random number for x and then you can see that it is not equivalent. Example: 30 - 10x7 = 40 but 10 (30-70) = -400

Answer:

c

Step-by-step explanation:

[tex]sin = \frac{opposite}{hypotenuse}[/tex]

it wants us to find sin a

the opposite of a is 24 and the hypotenuse is 26

so sin A = 24/26

[tex]cos = \frac{adjacent}{hypotenuse}[/tex]

it wants us to find cos a

the adjacent of a is 10 and the hypotenuse is 26

so cos A = 10/26

The maximum height is 36.75feet at 2.5 seconds. Using the quadratic equation, you can calculate the x coordinate of the vertex with -b/2a. In this case, the x coordinate of the vertex is the time the swipe card reaches its max height , and it is 2.5. To calculate the maximum height, substitute 2.5 into each variable of t in the original equation, and the solution is 36.75.

6/12+8/12+9/12=23/12=1 11/12

Answer:

D. 1 11/12

Step-by-step explanation:

Let's set up our common denominator first. To do this we need to find a number divisible by 2, 3, and 4.

Multiply 3 by 4 and you'll come out with 12. 12 is divisible by 2.

Now, multiply your fractions by the numbers they need to get the denominator to 12.

1/2 x 6/6 = 6/12

2/3 x 4/4 = 8/12

3/4 x 3/3 = 9/12

Add your numerators.

6 + 8 + 9 = 23.

Your fraction should look like 23/12.

Subtract 12 from 23 and you should get 11. Because 12 equals a whole, we can go ahead and put one.

1 and 11/12.

HELP IM SO CONFUSED about this

Answers

Answer:

180

straight

Step-by-step explanation:

Hello There

So we are given that angle a is equal to 11x + 37

we are also given that x = 13

because we are given the value of x we can simply find the measure of angle A by plugging in 13 to x into the expression

so basically angle A = 11 ( 13 ) + 37

11 * 13 = 143

143 + 37 = 180

now we want to classify the angle

here are the angle types and what they measure

(let x be measure of angle)

acute 0 < x < 90

so an acute angle has a measure of less than 90 degrees

the measure of angle A is 180 degrees so we can clarify that it is not an acute angle

right angle x = 90

a right angle has a measure of 90 degrees

angle a has a measure of 180 degrees therefore it is not a right angle

obtuse angle 90 < x < 180

the measure of an obtuse angle must be less than 180

because angle a = 180 it is not classified as an obtuse angle

straight angle x = 180

the measure of a straight angle is 180 degrees

angle a measure 180 degrees so we can conclude that angle a is a straight angle

Pls help complete for y=-7x +9 how do I do this

Answers

Answer:

You put the x in the x area and solve the problem.

For example:

    For 0 you would do y=-7(0) + 9

    Then if you do the math you get y = 9

    Therefore, your answer is 9.

-9 on both sides so the it now be, y-9=7x then you divide both sides by 7 which will be y-9/7= x.

Step-by-step explanation:

We have, 45% • x = 27

or,

Multiplying both sides by 100 and dividing both sides by 45,

we have x = 27 •  100/ 45

x = 60
