Solutions:
( , ) and
( , )

Answer:

let the angle be x then other angle is 4x

so,

x + 4x = 180

5x = 180

x = 36

so other angle I.e 4x = 4 × 36 = 144

Let one angle be x

Both are linear pair hence their sum will be 180

[tex]\\ \sf \longmapsto x+4x=180[/tex]

[tex]\\ \sf \longmapsto 5x=180[/tex]

[tex]\\ \sf \longmapsto x=\dfrac{180}{5}[/tex]

[tex]\\ \sf \longmapsto x=30[/tex]

[tex]\\ \sf \longmapsto 5x=5(30)=150[/tex]

Answer:

-9

Step-by-step explanation:

We need to write the terms from highest power to smallest power

-9x^5+10x^3+3x^2-7x+3

The leading coefficient is the number in front of the highest power

-9

Answer:

-9

Step-by-step explanation:

In a polynomial, the leading coefficient is the coefficient to the variable with the largest exponent.

In this polynomial, the variable with the largest exponent is x^5.

The leading coefficient is the number in front of the variable. In this case, the leading coefficient is -9.

So, the leading coefficient is -9.

Answer:

C

Step-by-step explanation:

We know that the first integer will be "l" so the second will be l + 1, third will be l + 2, fourth will be l + 3, and the fifth will be l + 4. The question says "the greatest is g" so that means that the fifth integer is the greatest meaning that is the value of g. Now that we know the value of g, we can substitute it into the equation they gave us and simplify.

l+(l+4)/2

2l+4/2

l + 2

Best of Luck!

Answer:

C

Step-by-step explanation:

say your 5 consecutive numbers are 6-10

if 6 is l and 10 is g then

6+10 over 2 equals 8

this proves that l+2 is correct since 6+2=8

Answer:

mean

Step-by-step explanation:

The mean is the center of a normal distribution

Triangles ABC and LBM are similar. We know this because AL and LB have the same length, so that AB is twice as long as either AL or LB. The same goes for MC and BM, and BC. The angle B is the same for both tirangles ABC and LBM, so the side-angle-side postulate tells us the triangles are similar, and in particular that triangle ABC is twice as large as LBM.

All this to say that LM must be half as long as AC, so LM has length (B) 14 cm.

Step-by-step explanation:

come on ! this is so simple. with just a tiny little bit of thinking you get this yourself.

1 inch = 50 miles.

so, how many miles are then 2 inches ? hmmm ?

could it be that it is just 2×1 inch = 2×50 miles ?

yes ! it is that simple !

2×50 = 100 miles.

and so, how many miles are 3 inches ?

uuuuuhhhh !

what do you think ?

3×1 inch = 3×50 miles

yeah !

3×50 = 150 miles !

yes, so simple, so easy.

this is like the old questions like "every child gets 2 pieces of candy. there are 6 children. how many pieces of candy do we need ?"

Answer:

3x=50-10y

Got it right on edge

The correct equation to find the number of each type of weight Bob has,

⇒ 3x = 50 - 10y

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Bob has some 10 lb weights and some 3 lb weights. Together, all his weights add up to 50 lb.

Let x represents the number of 3 lb weights and y represents the number of 10 lb weights.

Hence, The correct equation to find the number of each type of weight Bob has,

⇒ 3x + 10y = 50

⇒ 3x = 50 - 10y

Thus, The correct equation to find the number of each type of weight Bob has,

⇒ 3x = 50 - 10y

Explanation:

At the 60 day mark, the following number of widgets are produced

The fourth plant makes 150 widgets, which is between B and C

We see that the fourth plant does not make more than Plant A, so we can rule out choice A.

The fourth plant does not make less than Plant B, which allows us to rule out choice B.

The only thing left is choice C. Sure enough, this statement is true since 150 widgets made at the fourth plant is less than 300 made in Plant A. This is why choice C is the answer.

Answer:

x = 1

y=1.5

Step-by-step explanation:

3*1+2*1.5=6

The values of x and y in equation 6=3x+2y is for x is 1 and for y is 1.5.

We have given that,

x and y are integers and 0 < x < y.

6 = /3x+2y.

x=1 then

A statement of an order relationship greater than, greater than or equal to, less than, or less than or equal to between two numbers or algebraic expressions.

6=3+2y

6-3=2y

3/2=y

y=1.5

3*1+2*1.5=6

Therefore we get the values of x and y is for x is 1 and for y is 1.5.

=================================================

Explanation:

Since the decimal repeats itself infinitely (the 8s go on forever), this is one sign that we have a rational number.

Rational numbers always have some kind of infinitely repeating pattern when we convert them to decimal form.

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

Extra info (optional section)

If you want to determine what this number is equal to, then let's say that

x = 8.8888...

Multiplying both sides by 10 gets us

10x = 88.888....

Now we'll subtract the two equations

The 10x-x becomes 9x while the 88.8888...-8.8888... turns into 80

We're left with 9x = 80 which solves to x = 80/9

Therefore, 80/9 = 8.8888.... showing that we have a rational number

Any rational number is basically a fraction of two whole numbers.

The triangle RUS is similar to RST. 9/sqrt(90)=y/(3+x) and y^2=x^2+81. Solving all this will give x=27 and y=9*sqrt(10)

The angle addition postulate in geometry states that if we place two or more angles side by side such that they share a common vertex and a common arm between each pair of angles, then the sum of those angles will be equal to the total sum of the resulting angle.

X-value:

<RST = [tex]90^{0}[/tex]

[tex]tan( < RSU)= \frac{\overline R \overline U}{\overline S \overline U}[/tex]

[tex]tan( < RSU) = \frac{3}{9}[/tex]

[tex]< RSU = 18.435^{0}[/tex]

Angle addition postulate:

<RST = <RSU + <TSU

[tex]90^{0} =18.435^{0} + < TSU[/tex]

[tex]< TSU =71.565^{0}[/tex]

[tex]tan( < TSU) = \frac{\overline T \overline U }{\overline S \overline U}[/tex]

[tex]tan(71.565^{0})=\frac{x}{9}[/tex]

[tex]x=27[/tex]

Y-value:

<RST = [tex]90^{0}[/tex]

[tex]tan( < RSU)= \frac{\overline R \overline U}{\overline S \overline U}[/tex]

[tex]tan( < RSU) = \frac{3}{9}[/tex]
