Answer:

x=31

Step-by-step explanation:

Hey There!

Those angles are a pair of supplementary angles meaning that they will add up to equal

So to find what x equal we have to set up an equation and because those angles are supplementary we use the equation of 180=4x+x+25 because like before the sum of supplementary angles is equal to 180

Now that we have the equation it is time to solve for x

180=4x+x+25

Step 1 combine any like terms

Like terms are any similar variables or constants and in this case we have two like terms 4x and x so we should add them together

4x+x=5x

Now we have

180=5x+25

Step 2 our goal is to get the variable (x) on one side and the constant on the other. What we want to do is get rid of the 25 and to do that we subtract 25 but whatever we do to one side we have to do to the other

180-25=155

25-25 cancels out

now we have 155=5x

Our final step is to divide each side by 5

5/5 cancels out

155/5=31

We can conclude that x=31

Answer:

6 inches per year/ 6;1

Step-by-step explanation:

30;5 can be simplified into a unit rate by dividing by 5. 30/5=6 and 5/5=1. So its 6 inches per one year

Answer:

a + 5b + 5c

Step-by-step explanation:

here's your solution

=> 3a + 4b + 5c +(-2a) + b

=> solve for like term

=> 3a - 2a + 4b + b + 5c

=> a + 5b + 5c

Answer:

10P + 7m = 19 .......... 1

3P + 5m = 10.05 .......... 2

Step-by-step explanation:

Let the cost of pencil be represented by P, and felt-tip by m. So that;

Rodrigo bought 10 pencils and 7 felt-tip at the cost of $19.0.

⇒ 10P + 7m = 19 .......... 1

Melissa bought 3 pencils and 5 felt-tip at the cost of $10.05.

⇒ 3P + 5m = 10.05 .......... 2

From equations 1 and 2,

10P + 7m = 19 .......... 1

3P + 5m = 10.05 .......... 2

Multiply equation 1 by 3, and 2 by 10 to have;

30P + 21m = 57 ......... 3

30P + 50m = 100.5 ....... 4

Subtract equation 3 from 4,

30P - 30P + 50m - 21m = 100.5 - 57

29m =43.5

m = [tex]\frac{43.5}{29}[/tex]

 = 1.5

m = 1.5

Substitute the value of m in equation 2,

3P + 5m = 10.05 .......... 2

3P + 5(1.5) = 10.05

3P = 7.5 = 10.05

3P = 3

P = 1.0

Thus, the cost of a pencil is $1.0 and that of a felt-tip is $1.5.

Answer:

No

Step-by-step explanation:

You use the Pythagorean Therom and square your legs (5 and 12) and your hypotenuse (14) it would add up to 25+144=196.

This is not true since 144+25 is 169, not 196

Answer:

No, it is not a right triangle.

Step-by-step explanation:

You can determine whether a triangle is a right triangle by using the pythagorean theorem.

a^2 + b^2 = c^2

c will always be the longest side of the triangle, so in this case you need to substitute 5 and 12 in for a and b and see if it simplifies to 15.

5^2 + 12^2 = c^2

25 + 144 = c^2

c^2 = 169

c = 13

C would be 13, not 15, so the triangle is not a right triangle

v = 10.5

Step-by-step explanation:

v = l× w× h

v = 2 × 1 1/2 × 3 1/2

good luck, i hope this helps :)

Answer:

10 1/2

Step-by-step explanation:

V = lwh

l = 2

w = 1 1/2 or 1.5

h = 3 1/2 or 3.5

2 x 1.5 x 3.5

10.5 or 10 1/2

Answer:

Step-by-step explanation:

Answer:

answer is below

Step-by-step explanation:

x - 2y = 12

First step is to solve for y, so

[tex]x - 2y = 12[/tex]

Then, subtract x on both sides to isolate the variable, y.

[tex]-2y = -x + 12[/tex]

Divide both sides by -2

[tex]y = \frac{1}{2}x - 6[/tex]

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

The domain is {-3,-1,0,2,5}

Domain is the set of x values

Range is the set of y values

We are given the domain x, we need to find out the y values using the equation: [tex]y= \frac{1}{2}x - 6[/tex]

[tex]y = \frac{1}{2}(-3) -6 = \frac{-15}{2} = -7.5\\\\y = \frac{1}{2}(-1) -6 = \frac{-13}{2} = -6.5\\\\y = \frac{1}{2}(0) -6 = -6\\\\y = \frac{1}{2}(2) -6 = -5\\\\\\y = \frac{1}{2}(5) -6 = -\frac{7}{2} = - 3.5[/tex]

therefore,

when x is -3: y = -7.5

when x is -1: y = -6.5

when x is 0: y = -6

when x is 2: y = -5

when x is 5: y = -3.5

Range is {-7.5, -6.5, -6 , -5, -3.5}

hope this helps and is right :)
