Can some help ?? I’ll give brainliest

Answer: x = 7

Step-by-step explanation:

7x+9=58

8x+2=58

These are congruent angles so they are the same value.

4/5 * 3 = 12/5

20 * 3 = 1 hour = 60 min

Answer:

c hope this helps

explain i did it on paper

Answer:

55

Step-by-step explanation:

2x+5 x-5 combine these to get 3x

then you would divide 180 by 3

so u would get 60 = x

60-5 =55

I thank it's 55 It wont let me post it because its too short

Answer:

48%

Step-by-step explanation:

If the coin is flipped 250 times, and lands on tails 120 times, set this up as a fraction. Put 250 on the bottom, and 120 on the top (because you want to know percentage of tails for 250 coin flips) to get 120/250. This is 0.48, to turn this into a percentage multiply by 100, 48%. You can check this answer by taking 0.48(250) and you will get 120.

Answer:

The slope is -2.

Step-by-step explanation:

m=y2-y1/x2-x1            (also, y1-y2/x1-x2 is also true.)

=23-15/6-10                  m=15-23/10-6

= 8/-4                            =-8/4

=4/-2                             =-4/2

= 2/-1                             =-2/1

m=-2                             m=-2

A=False

B=True

C=True

Answer:

52

Step-by-step explanation:

m∠A + m∠B + m∠C = 180 | Sum of ∠s in △

28 + x-4 + 2x = 180 | Substitution

x = 52 | Algebra

Hi there!

[tex]\large\boxed{x = 8}[/tex]

Recall that all angles in a triangle sum up to 180°, therefore:

(9x + 3) + (5x - 2) + (11x - 21) = 180

Combine like terms:

9x + 5x + 11x + 3 - 2 - 21 = 180

25x -20 = 180

Add 20 to both sides:

25x = 200

Divide both sides by 25:

x = 8°

Answer:

Step-by-step explanation:

we know that the sum of the angles in a triangle is 180

(5x-2)+(9x+3)+(11x-21)=180

=5x-2+9x+3+11x-21=180

25x=180+20

25x=200

x=8

Answer: $8.50/pound

Step-by-step explanation:

Price per pound --> take the total price and divide it by the number of pounds

$22.10 / 2.6 pounds = $8.50/pound

Answer:

$8.50

Step-by-step explanation:

take 22.10 divide it by 2.6 and you will get your answer.

Hope this helps

Answer:

z=6

Step-by-step explanation:

First you add -8 to both sides. Now the equation is [tex]\frac{z}{-2} \\[/tex]=-3. Now you must multiply both sides by -2, so you get z=6

Answer:

[tex]T = 100[/tex]

Step-by-step explanation:

See attachment for parallelogram TRIK

Given

[tex]T = 5x[/tex]

[tex]I = 2(x + 30)[/tex]

Required

Determine T

Because T and I are opposite angles of the parallelogram, then they are congruent.

i.e.

[tex]T = I[/tex]

Substitute values for T and I

[tex]5x = 2(x + 30)[/tex]

Open bracket

[tex]5x = 2x + 60[/tex]

Collect Like Terms

[tex]5x - 2x = 60[/tex]

[tex]3x = 60[/tex]

Solve for x

[tex]x = \frac{60}{3}[/tex]

[tex]x =20[/tex]

Recall that:

[tex]T = 5x[/tex]

[tex]T = 5 * 20[/tex]

[tex]T = 100[/tex]

Answer:

1

Step-by-step explanation:

Answer:

The answer is 1

Step-by-step explanation:

Using the rise over run strategy, you can get this answer by...

1. Look at the line and graph 2 points. ( 1 , 1 ) & ( 2 , 2 ).

2. Do the rise over run thing. ( how am I going to get from 1 point to the other.)

You get to it by rising 1 and running 1. The pattern is self explanatory.

3. Divide rise over run and the quotient is your answer

1 divided by 1 is 1.

Answer:

x = ± [tex]\sqrt{20}[/tex]

Step-by-step explanation:

Given

x² = 20 ( take the square root of both sides )

x = ± [tex]\sqrt{20}[/tex]

which can be simplified to

x = ± 2[tex]\sqrt{5}[/tex]

[ ± means plus or minus ]
