Answer:
Density = 1.042 grams /cm^3
Step-by-step explanation:
Work out the mass of each of three in a unit volume (cm^3)
Givens
- Apple Juice = 1.04 grams / cm^3
- Fruit Syrup = 1.6 grams / cm^3
- Sparkling water = 0.99 grams / cm^3
Mixture
35 cm^3 Apple Juice = 1.04 grams / cm^3 * 35 cm^3 = 36.4 grams
25 cm^3 Fruit = 1.6 grams/cm^3 * 25 cm^3 = 40 grams
270 cm^3 water = 0.99 * 270 267.3 grams
Total Mixture
- Volume = 25 + 35 + 270 = 330 cm^3
- Mass = 36.4 + 40 + 267.3 = 343.7 grams
Density
Density = mass / volume = 343.7 / 330 = 1.0415
Answer
1.042 grams / cm^3
It equals 5 or -2
If you need working feel free to message me x
X= 3

I used the substitution method
Answer:
variable
The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.
Step-by-step explanation:
Answer:
y=2x-5
Step-by-step explanation:
First simplify: y-1=2x-6
y-1=2(x-3)
First simplify and distribute everything.
<u>y-1=2x-6</u>
So, x equals 2 because it got distributed into the numbers inside the parenthesis. Same with the 2 and -3. They multiplied to become -6.
Since it's y-1=2x-6, you can simplify it even more so the -1 goes to the other side and turns into positive 1.
<u>y - 1 (+ 1) = 2x -6 (+ 1)</u>
-1(+1)=0 which leaves just the variable y on the <em><u>left side</u></em>.
-6(+1)=-5 which leaves 2x-5 on the <em><u>right side</u></em>.
This results in y=2x-5. Hope this helped ;)
