. Which ordered pairs in the form (x, y) are solutions to the equation 7x – 5y = 28?
Choose all answers that are correct.
A. (−6, −14)
B. (−1, −7)
C. (4, 10)
D. (7, 9)

Answers

Answer 1

Answer:

A and B

Step-by-step explanation:

to determine which pairs are solutions , substitute the x and y coordinates into the left side of the equation and if equal to the right side then solution.

A (- 6, - 14 )

7(- 6) - 5(- 14) = - 42 + 70 = 28 ← true , so solution

B (- 1, - 7 )

7(- 1) - 5(- 7) = - 7 + 35 = 28 ← true , so solution

C (4, 10 )

7(4) - 5(10) = 28 - 50 = - 22 ≠ 28 , not a solution

D (7, 9 )

7(7) - 5(9) = 49 - 45 = 4 ≠ 28 , not a solution

PLEASE HELPP!!

Answers

The answer is c 19
38/2=19
Step-by-step explanation
The answer is d. 18 and e. 12.

Explanation:

2x - 5 < 33

2x < 33 + 5

2x < 38

x < 38/2

x < 19

x must be smaller than 19.

It can’t be 19 because it didn’t say smaller than or equal to.

So the answer is 18 and 12.

pls help me solve surds , √75 ,√48, √12,√125,√28. pls help​

Answers

√75 = √(5²×3) = √5² √3 = 5√3 = 8.66

√48 = √(4²×3) = √4² √3 = 4√3 = 6.93

√12 = √(2²×3) = √2² √3 = 2√3 = 3.46

√125 = √(5²×3) = √5² √3 = 5√3 = 11.18

√28 = √(2²×7) = √2² √7 = 2√7 = 5.29
All the answers are rounded off to the nearest hundredth.

√75 = 5√3 = 8.66

√48 = 4√3 = 6.93

√12 = 2√3 = 3.46

√125 = 5√5 = 11.18

√28 = 2√7 = 5.29

The best way to measure an angle is to use a protractor. To do this, you'll start by lining up one ray along the 0-degree line on the protractor. Then, line up the vertex with the midpoint of the protractor. Follow the second ray to determine the angle's measurement to the nearest degree

John joined a gym for 6 months. He pays 20$ per month plus a membership fee. If his bill is 150$, what was the membership fee?

Answers

Answer:

Step-by-step explanation:

If he's been at the gym for 6 months, and he is charged $20 each month, then he has paid $120 dollars, not counting his membership fee. His total bill is $150.

150-120= $30

His membership fee was $30.

Hope this helps!

Mark Brainliest plz!

x is the number of months and y is the membership fee

[tex]cost = 20x + y[/tex]

[tex]150 = 20(6) + y[/tex]

[tex]150 = 120 + y[/tex]

[tex]150 - 120 = 120 - 120 + y[/tex]

[tex]30 = y[/tex]

The membership fee was $30.
