can you answer it. please

Answers

Answer 1

Answer:

5x + 10 + 55 = 90

5x = 90 -55 - 10

5x = 90 - 65

5x = 25

5x ÷ 5 = 25 ÷ 5

x = 5

Answer 2

Answer:

x=5

Step-by-step explanation:

If you replace the x in (5x+10)º

(5x+10)º

[5(5)+10]º

[25+10]º

= 35º

Combine the sums for angles M and R

55º+35º

=90º

Therefore, the answer is x=5.

because the service was

$18.10. How much was the
original bill?

Answers

Answer:

72.4$

Step-by-step explanation:

We can use cross multiplication here

[tex]\frac{18.10}{originalbill} = \frac{25}{100}[/tex]

18.10 x 100 = 25 x original bill

1810 = 25 x original bill

If m∠ABC=7x-2 and ∠CDE=5x+16 are congruent, find m∠ABC?

Answers

Answer: m∠ABC = 61°

Step-by-step explanation: Since angles are congruent, make the equation

7x-2 = 5x + 16

7x-5x = 16 +2

2x = 19

x = 9

Substitute 9 for x

7(9) -2 = m∠ABC . and 5(9) + 16 = m∠CDE

63-2 = 61° = m∠ABC 45 + 16 = 61 True!

A man has 27 coins in his pocket, all of which are dimes and quarters. If the total value of his change is 525 cents, how many dimes and how many quarters does he have?
Your answer is
number of dimes equals=

number of quarters equals=

Answers

Answer:

17(quarters)

10(dimes)

Step-by-step explanation:

Hi there !

dimes = 0.1$ = 10c

quarters = 0.25$ = 25c

d + q = 27 => d = 27 - q

10d + 25q = 525

replace d

10(27 - q) + 25q = 525

270 - 10q + 25q = 525

25q - 10q = 525 - 270

15q = 255

q = 255 : 15

q = 17(quarters)

d = 27 - q

= 27 - 17

d = 10(dimes)

Good luck !

What is the distance between (4, 7) and (2,2)?

Answers

let's see what to do buddy...

To find the distance between two points, we have the following relation, which is derived from the Pythagorean relation, and we do not need to prove it :

a = ( 2 , 2 ) and b = ( 4 , 7 )

[tex]d = \sqrt{ ( \: {y(b) - y(a)} \: )^{2} + ( \: {x(b) - x(a)} \: )^{2} } \\ [/tex]

Now just put the coordinates in the equation :

[tex]d = \sqrt{ ({7 - 2})^{2} + ({4 - 2})^{2} } \\ \: \: \: d = \sqrt{ {5}^{2} + {2}^{2} } \\ d = \sqrt{25 + 4} \\ d = \sqrt{29} [/tex]

So the distance between them equal :

[tex] \sqrt{29} [/tex]

And we're done buddy.

Thanks for watching good luck ♥️♥️♥️♥️♥️.
