Solve for X in the rectangle?

Answers

Answer 1

Answer:

x=6

Step-by-step explanation:

13x+12=90

13x=78

x=6

Answer 2

The value of x in the rectangle is 6.

What is Trigonometry?

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

The given quadrilateral is a rectangle.

In rectangle each angle has 90 degrees.

So equate 13x+12 and 90 degrees to get x

13x+12=90

Subtract 12 from both sides

13x=90-12

13x=78

Divide both sides by 13

x=6

Hence, the value of x in the rectangle is 6.

Write the equation of the line given the points (2,0) and (3.-1)

Answers

Answer:

y = -1x + 2

Step-by-step explanation:

We need to find y = mx + b

Use the following equation

[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Plug in the values

[tex]\frac{-1-0}{3-2}[/tex] = [tex]\frac{-1}{1} = -1[/tex]

We have found the slope(m) which is -1

We have to find y-int b

Plug in any given x,y into the slope formula

-1 = -1(3) + b

-1 = -3 + b

2 = b

At last the formula is

y = -1x + 2

The numerator of a fraction is 6 more than the denominator. If 5 is subtracted from the denominator, the fraction becomes 3/2. Find the fraction

Answers

Answer:

The fraction is 32/27

Step-by-step explanation:

let the fraction be x/y

x - y = 6

x = 6 + y ••••••(i)

This is according to the first sentence

Furthermore;

x/y-5 = 3/2

2x = 3(y-5) •••••(ii)

Substitute

2(6 + y) = 3y - 15

12 + 2y = 3y - 15

3y -2y = 12 + 15

y = 27

x = 6 + y

x = 6 + 27 = 33

Cassidy the Clown does face painting at the city carnival. She paints 8 faces every 21 minutes. Write an equation that related the number of faces she paints (y) and the time she spends painting (x)
ANSWER WITH A PICTURE ASAP

Answers

Answer:

8y=21x

Step-by-step explanation:

i'm not sure how to draw this out in a picture but the equation is above.

like the question states, Cassidy paints 8 faces in every 21 minutes. the amount of time she spends painting one face would be figured out by dividing 21 by 8 giving you 2.625minutes so i would just say around 3 minutes. so to draw a picture maybe just draw 8 faces and then circle them and say 21 minutes and then put x (to show the time she spent painting each face) under the faces in the picture and then show your work solving this.

in order to find out the ratio of time spent drawing one person's face we have to take the information given and divide the total of 21 minute span by the 8 different faces she painted in order to find how long she spends on 1 face.

Given the function f(x)=-x+3, find the value of f(13).

Answers

F(13) means x equals 13.

Replace x in the equation with 13 and solve:

-13 + 3 = -10

F(13) = -10

Answer:

-10

Step-by-step explanation:

if the x in f(x) is 13, then the x in the equation is 13 and there is a negative sign in front so it is negative 13 plus 3 which is negative 10

Find the inequality represented by the graph.

Answers

Answer:

y > 1/3 x - 3

Step-by-step explanation:

First, it would be easiest to find the equation of the line from the two integer points given, which are (0, -3) and (3, -2).

Find the change of y over the change of x to get the slope of the line.

(-2 - (-3))/(3 - 0) = 1/3

Since the line intercepts the y axis at (0, -3), the equation of the line would be

y = 1/3x - 3

We can see that the shaded portion is above the line, (and that the line is dotted) so this graph represents

y > 1/3 x - 3

the sum of two numbers is 103. If the greater number is divided by the smaller number the quotient is 2 and the remainder is 10 find the number

Answers

9514 1404 393

Answer:

31 and 72

Step-by-step explanation:

Let x be the smaller number and y be the larger number. Then we have ...

x + y = 103 . . . . . sum is 103

y = 2x +10 . . . . . y/x is 2 remainder 10

Substituting for y, we get ...

x + (2x +10) = 103

3x = 93

x = 31

y = 103 -31 = 72

The two numbers are 31 and 72.

Answers

Answer:

the

answer

Answer:

The 30% of a number can be calculated multiplying that number by 0.3, so, if we call the number we don't know x, we can write this equation:

0.3x = 12

And then solve it for x::

x = 12/0.3 = 40

So now we know that the number is 40.

We can replace the 40 in the equation to get if our answer is correct or not..

30% of 40: 0.3 * 40 = 12

And then, we see it's correct
