Which of these equations are true when the value of y is 27?
I. −9 + y = 18
II. −18 + y = −45
III. 5y = 135
IV. 2y = 29

Answers

Answer:

I. -9 + y = 18

Step-by-step explanation:

Double-check to see if I was correct

The equations I. and III. satisfies the condition when y = 27

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

The value of y = 27

So , substituting the value of y in all of the given equations , we get

I.  

-9 + y = 18

when y = 27

Substituting the value of y , we get

-9 + 27 = 18

18 = 18

So , I. satisfies the condition and the equation is TRUE

II.

-18 + y = 45

when y = 27

Substituting the value of y , we get

-18 + 27 = 45

9 ≠ 45

So , II. does not satisfy the condition and the equation is FALSE

III.

5y = 135

when y = 27

Substituting the value of y , we get

5 x 27 = 135

135 = 135

So , III. satisfies the condition and the equation is TRUE

IV.

2y = 49

when y = 27

Substituting the value of y , we get

2 x 27 = 29

54 ≠ 29

So , IV. does not satisfy the condition and the equation is FALSE

Hence , the equations I. and III. are TRUE

For a two-day rental at the surf shop, it cost $55 to rent a surf board and $70 to rent a paddle board. On a certain weekend, the surf shop rented 51 total surf boards and paddle boards and made $3300. How many paddle boards were rented?

Answers

Answer:

7 paddleboards

Step-by-step explanation:

In order to solve this, you have to find the total amount that they earned by renting surfboards.

To find this you multiply 55 x 51 =2,805.

Then you use this factor and subtract it from the total amount they earned.

$3,300 - $2,805 = $495.

This shows us that they earned a total of $495 from renting out paddle boards. To find out how many paddle boards were rented out you have to divide $495 by $70 which is how much they charge to rent paddle boards.

495/70 = 7

In conclusion, they rented out 7 paddle boards.

C) (2, 4)
B) (-4,5)
D) No solution

Answers

Answer:

B). (-4, 5)

Step-by-step explanation:

-2x – 3y = -7 | ×2 |

-4x + y = 21 | ×1 |

-4x – 6y = -14

-4x + y = 21

____________ --

-7y = -35

y = -35/-7

y = 5

-4x + y = 21

-4x + 5 = 21

-4x = 21 - 5

-4x = 16

x = 16/-4

x = -4
