Which number will make the fractions equivalent 25/35

Answers

Answer 1

Answer: You could make an equivalent fraction by multiplying both numbers by 2.

$25*2=50\n35*2=70\n \n (50)/(70)$

Answer 2

Answer: $(25)/(35) = (25:5)/(35:5) = (5)/(7) \n \n (25)/(35) =(25\cdot2)/(35\cdot2)= (50)/(70) \n \n (25)/(35) = (25\cdot4)/(35\cdot4) = (100)/(140)\n \n (25)/(35) = (25\cdot10)/(35\cdot10) = (250)/(350)$

Which expression is equivalent to −15x + 6

Answers

The answer is -15x + 6= -9x

If f(x) varies directly with x, and f(x) = 18 when x = 2, find the value of f(x) when x = 6.A.
6

B.
18

C.
36

D.
54

Answers

If f(x) varies directly with x, that mean there exists some unknown number k such that f(x) = kx.

So we were given that f(x) = 18 when x = 2. So plugging in these values will help you find the value of k.

18 = 2k

k = 9

So we know that k=9, therefore f(x) = 9x.

Now, at x=6, you have f(6) = 9·6 = 54

Therefore answer is D.

Answer:

no solutions

Step-by-step explanation:

x+2 1

------------- = ----------

2x-2 2

We can solve this using cross products

(x+2) *2 = 1*(2x-2)

Distribute

2x+4 = 2x-2

Subtract 2x from each side

2x-2x+4 = 2x-2x-2

4 = -2

This is never true so there are no solutions

Answer:

Step-by-step explanation:

First cross multiply:

2(x+2)=2x-2

Then Simplify:

2x+4=2x-2

Finally, Solve:

2x-2x=4+2

Ans: No Solution

Estimate then record the product $473x9

Answers

So because 9 and 10 are close to each other, and the fact that 10 is really easy to multiply by, you do 473 x 10 which is 4730, because you just add a 0 to the end.
This means that an estimate is 4730 or if you want to be less specific, <4730, because 9 is less than 10.
The actual product though is 4257.

the Answer is 4,267
473 times 9 is 4,267 because u always multiply the number that is below the number that u are multiplying 4,267 times 9. 9 times 7 is 27 9 times 7 is 64 plus 2 is 66 and 9 times 4 is 36 so always multiply that small number with the numbers that is bigger
