solve the system y= 4x + 1 and 3x+2y =13

The sum of all the angles in a triangle is 180 degrees, so we get the equation:

  [tex]55 + 54 + (x + 74) = 180\\x + 183 = 180\\x = -3[/tex]

The value of x is -3.

Hope that helps!

Answer:

[tex]\frac{2}{3} + \frac{1}{5} = \frac{10}{15} +\frac{3}{15} = \frac{13}{15}[/tex]

PLEASE BRANLIEST ANSWER IS CORRECT I CHECKED

Step-by-step explanation:

First, find the least common denominator which is 15.

[tex](\frac{5}{5})\frac{2}{3} + (\frac{3}{3})\frac{1}{5}[/tex]

When we multiply by 5/5 or 3/3 we are not changing the value of the fraction, just turning the denominator into one which we can work with the other fraction's denominator.

After simplification:

[tex]\frac{10}{15} + \frac{3}{15}[/tex]

Now we can add:

[tex]\frac{13}{15}[/tex]

Answer:

13/15

Step-by-step explanation:

because 5 x 2=10                  3 x 1=3

              5 x 3=15                5 x 3=15

   10/15+3/15= 13/15

Answer:

-2 x 2 - 4x + 3

If x = -2, then . . .

Answer:

3

Step-by-step explanation:

you have 1/3, to find out how many ninths you have, you must multiply the denominator by three (because 3*3=9). whatever you multiply on the bottom you must multiply on the top (if you don't do that then it's not the same as 1/3 anymore)

therefore 1/3 == (1*3)/(3*3) == 3/9

if you want to know how many twelves it was then you multiply by 4 to get 12 on the bottom:

1/3 == (1*4)/(3*4) == 4/12

therefore 1/3 == 3/9 == 4/12. they are all the same fraction

Answer:

y=3/4x

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(3-(-3))/(4-(-4))

m=(3+3)/(4+4)

m=6/8

m=3/4

y-y1=m(x-x1)

y-(-3)=3/4(x-(-4))

y+3=3/4(x+4)

y=3/4x+12/4-3

y=3/4x+3-3

y=3/4x

Answer:

d

Step-by-step explanation:

The dashes on the sides of the triangles mean that they are equal in length.

Isosceles triangle: 2 sides of equal length

Equilateral triangle: 3 sides of equal length

Triangle a doesn't have any dashes, so all the sides are different length.

Triangle b has 2 sides that each have the same number of dashes, so these sides are equal in length → Isosceles triangle

Triangle c has 2 sides that each have the same number of dashes, so these sides are equal in length → Isosceles triangle

Triangle d has 3 sides that each have the same number of dashes, so these sides are equal in length → Equilateral triangle

Answer:

25/13 miles in an hour

Step-by-step explanation:

So she walks 1/13 mile per 1/25 hour.

To find the miles in an hour, just multiply the 1/25 hour by 25/

1/25 hour * 25 = 1 hour.

1/13 mile * 25 = 25/13 miles in an hour

Answer:

H=100

Step-by-step explanation:

To solve H simply simplify both sides of the equation then isolate the variables.

Answer:

h=100

Step-by-step explanation:

h/5 -28=-8

put like terms together( unknowns on one side, knowns on the other)

h/5= -8+28  

h/5= 20

Multiplying both sides by 5 to get rid of the denominator

5(h/5) =5(20)

h=100

[tex]5!+50\\\\(5*4*3*2*1)+50\\\\120+50\\\\170[/tex]

Question

5! + 50

Step-by-step explanation:

about factorial

5!

=5 × 4 × 3 × 2 × 1

=20 × 3 × 2 × 1

=60 × 2 × 1

=120 × 1

=120

the result of the factorial 5! is 120

now we just add 120+50

120 + 50

120

50

———+

170

so the result of 5! + 50 is 170

Answer:

9.48683

Step-by-step explanation:

using the formula:

Find the difference between coordinates:

(x2-x1) = (6 - -3) = 9

(y2-y1) = (1 - 4) = -3

Square the results and sum them up:

(9)2 + (-3)2 = 81 + 9 = 90

Now Find the square root and that's your result:

Exact solution: √90 = 3√10

Approximate solution: 9.4868

Answer:

Step-by-step explanation:

∠WTX = ∠WUV (facing same arc WV)

9x + 18 = 15x

6x = 18

x = 3

In ΔXUV,

∠VXU = 180 - 15x - (3x + 21)

= 180 - 18x - 21

= 159 - 18(3)

= 159 - 54

= 105°

thanks

your gurl unique

1) 12, 14

This is the answer because each increasing number was increased by 2, so if you add 2 to 10, you'd get 12. If you add 2 to 12, you would get 14.

2) 50, 54

Same explanation as above but for the number 4.

3) 68, 50

Same explanation as 1, but with subtracting the number 6.

4) 67, 69

Same as number 1

5) 103, 101

Same as number 3 but subtracting the number 2

The answer for this question is 6,304

Answer:

C

Step-by-step explanation:

On each linear pair, there is one of the Vertical angles and an angle shared between the two angles. This means we can use the fact that supplements of the same angle are congruent.

The basis for the proof vertical angles are congruent is " two angles that are each supplementary to a third angle are congruent".

Vertical angles are a pair of non-adjacent angles formed by the intersection of two straight lines.

In the provided figure.

∠1 + ∠2 = 180 degrees ( linear pair of angles)...(i)

∠ 1 + ∠4 = 180 degrees ( linear pair of angles)...(ii)

According to transitive property, if a = b and b = c then a = c

Therefore,

∠1 + ∠2 = ∠1 + ∠4...(iii)

⇒∠2 = ∠4

Similarly, we can prove that

∠1 = ∠3

Therefore, we conclude that vertically opposite angles are always equal.

Hence, the basis for the proof vertical angles are congruent is " two angles that are each supplementary to a third angle are congruent".

Thus, statement c is correct.

Answer:

c = 21º

d = 100º

Step-by-step explanation:

In questions like this, always find the angles you can find and it will help you find more and more.

So let's start by finding angle e. We know that the sum of the angles in any triangle is equal to 180. So let's do 180 - (20 + 20) = 140

angle e = 140º

Now we don't know either C or D and are unable to find them with only e, so let's find other angles to help us. The 4 angles that aren't known at each corner of the square are easy to find, as we know for sure that they fully equal to 90º. So 90 - 20 = 70º. Both angles at the bottom corners = 70º. Now for the top corners: top left = 90 - 30 = 60º and top right = 90 - 40 = 50º.

As well as this, we can find a and b as well, but I think you already figured that out. angle a: 180 - (30 + 40) = 110º, angle b: 360 - (140 + 110) = 209º

Now we can figure out c and d, because we know that the sum of all angles in any quadrilateral is 360º. So the trapezium on the left, angle c: 360 - (70 + 60 + 209) = 21º. And finally right trapezium, angle d: 360 - (70 + 140 + 50) = 100º
