Answer 1

Answer:

x=[tex]-\frac{113}{3}[/tex]

Step-by-step explanation:

First, we need to solve the angle inside the triangle. That would be 55+40+angle measure=180

angle measure=85°

Now that we know that, we can solve for x by setting 85-3x-18 equal to 180° because these two values form a linear pair which is 180°.

Let's use some simple algebra to solve for x:

85-3x-18=180

67-3x=180

-3x=113

x=[tex]-\frac{113}{3}[/tex] or about -37.67

Hope this helps!! :)

the ratio of number of girls and boys in a class is 4:3 if there are 20 girls find the number of boys. plz do it in process​

Answers

Answer:

15 boys

Step-by-step explanation:

Whatever number one side of the ratio is multiplied by, the other side has to be multiplied by that same number. So, we have to find the number that 4 is multiplied by to get 20. We can represent this as an equation, where the unknown number is x:

4x = 20

Divide both sides of the equation by 4 to find the value of x:

x = 5

4 was multiplied by 5 to get 20.

To find the number of boys, multiply 3 by 5:

3 * 5 = 15

If there are 20 girls, there will be 15 boys.

Is this congruent by SSS, SAS, AAS, ASA? Pls lemme know! Only if you know though

Answers

9514 1404 393

Answer:

  SSS

Step-by-step explanation:

Two sides are marked congruent and the third side is shared. It is congruent to itself.

Hence, all three sides are congruent, and you can invoke the SSS congruence postulate to say the triangles are congruent.

Absolutely SSS because 2 pairs side are already equal as the question given. The last one is the middle line that lie on each other so it’s equal( the same side).

om each drop-down menu. Megan's commute to work includes an 8-mile drive and a 21-mile train ride. This expression can be used to find the total time it takes Megan to get to work, where xis her average driving speed in miles/hour. 21​

Answers

Answer: The answers are x+20 and 0.50 hrs

I just took the test so ik these are right

The total time it takes Megan to get to work,

⇒ (8 / x) + (21 / y)

where, x is her average driving speed in miles/hour. 2

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10

Given that:

Average driving speed = x mph

Miles driven to work = 8 mile

Miles by train to work = 21 miles

Average train speed = y

Hence, Total time taken to get to work is,

We know that;

⇒ Time taken = distance / speed

Hence,

⇒ Time taken = total distance / average driving speed

⇒ Total time taken = (8 / x) + (21 / y) hours

⇒ Total time taken = (8 / x) + (21 / y) hours

Graph of an inequality

The graph represented in the image is a line and we have two clear points through which the line passes.

Those points are (0,1) and (5,0).

The equation of a line can have the slope-intercept form:

y=mx+b

Substituting the point (0,1):

1=0+b

b=1

Substituting the point (5,0):

0=m(5)+1

Solving for m:

[tex]\displaystyle m=-\frac{1}{5}[/tex]

The equation of the line is:

[tex]\displaystyle y=-\frac{1}{5}x+1[/tex]

The origin belongs to the solution if we substitute (0,0) the inequality should stand:

0<1

Or:

0≤1

Since the line is dashed, the boundary line is not part of the solution

Thus the inequality is:

[tex]\boxed{\displaystyle y<-\frac{1}{5}x+1}[/tex]

What is an equation in point-slope form of the line that passes through (-7. 1) and (-3, 9)?
A. y+ 3 = 2(x-9)
B. y-3 = 2(x +9)
C. y + 9 = 2(x - 3)
D. y - 9 = 2(x + 3)

Answers

Answer:

D

Step-by-step explanation:

general equation of point slope is

(y-y1)=m(x-x1) where

m-is the slope

(x1,x2) is any point that belongs to the line

For (-7,1) and (-3, 9) you have to

first find the slope

m= (y2-y1) /(x2-x1) = (9-1)/ (-3- -7)= 8/(-3+7) = 8/4 =2

second pick any of your 2 given points for example (-3, 9)

now you substitute m=2, and (-3,9) in your general equation

(y-9) = 2( x- -3) so the equation is (x-9) =2(x+3)

What is the slope? please make sure you explajn

Answer: the slope is the rise over run of the line on a grid so the amount it takes for a point to go up and over

‘slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run"’
