I really need help finding the solution!!

Mathematics
1 answer:
Mrac [35]2 years ago
3 0

Answer:

-0.5 is not a solution

2 is a solution

Step-by-step explanation:

To check if something is a solution of the equation, you need to substitute the value in place of the variable

15 + 2y = -12 - 4y

15 + 2(-0.5) = -12 - 4(-0.5)

15 - 1 = -12 + 2

14 ≠ -10 ∴ -0.5 is not a solution

5 - 2(3x + 5) = 3 - 10x

5 - 2[3(2) + 5] = 3 - 10(2)

5 - 2(6 + 5) = 3 - 10(2)

5 - 12 - 10 = 3 - 120

-17 = -17 ∴ 2 is a solution

The measurement, y, varies directly with regard to another value, x. If y = 9 and x = 24, find x for y = 25.
Degger [83]

Answer:

x=66.667

Step-by-step explanation:

Basically, if y varies directly with a value x, you get an equation of the form y=kx, where k is a constant. To answer the question, first substitute 9 into y, and 24 into x.

                                                   9=24k

                                                   k=0.375

k is 0.375, so to get x, substitute 0.375 into k and 25 into y

                                                   25=0.375x

                                                     x=66.667

And we got it!
