Mathematics
1 answer:
Anestetic [448]3 years ago
8 0
1. x/6 = 15 - 4
x = 11 × 6
x = 66

2. 2/7x = 3/14 - 1/7
2/7x = 3 - 2/14
2 = 7x/14
x = 4

3. 4+10 = x/2
14 × 2 = x
x = 28

in one version of a trail mix, there are 3 cups of peanuts mixed with 2 cups of raisins in another version of trail mix, there a
vlada-n [284]

Based on the ratios of the peanuts mixed with raisins in the versions of the trail mix, the ratios are equivalent for both mixes.

<h3>What are the ratios?</h3>

The first ratio is:

3 : 2

When taken to the simplest terms it is:

3/2 : 2/2

1.5 : 1

The second ratio is:

4.5 : 3

4.5/3 : 3/3

1.5 : 1

The ratios of the peanut and raisins mix are therefore equivalent.

What is the domain of the function y = √x + 4 ?
puteri [66]

Hello from MrBillDoesMath!

Answer:

Domain:  x >=0 for both cases


Discussion:

Assuming we are dealing with real valued functions, the domain of

y = x^(1/2) +4

is the set of all "x" such that x>= 0  (so we are taking the square root of a positive, or zero, real number)


The domain of  x^(1/2) +6 -7 is the same as for the last function  and for the same reason.


Thank you,

MrB

3x+4+8x-28=180 what x
Paraphin [41]
The equation simplified (combine like terms) would be 11x+(-24) =180.
Since adding a negative is the same as subtracting a positive, you could also write it as this: 11x-24=180. Next step is isolate the variable, so to do that you need to add 24 to both sides of the equation: 11x-24+24=180+24. This is the same as 11x=204. Now to get only one of the variable, you need to divide both sides by 11. x=18.54 repeating or x=18 6/11. Hope this helped!
