Please help! Math problem is attached!!
Tamiku [17]

Answer:

Ounces of strawberry juice: 20 ounces

Ounces of water: 80 ounces

Step-by-step explanation:

For this problem, we can use the equation:

x + y = 100 ounces

Where x = The number of ounces of strawberry juice

and y = The number of ounces of water

Since we know that Molly uses four times as many ounces of water for each ounce of strawberry juice, we can conclude that:

y = 4x

With this information, we can use substitution to solve for x.

x + y = 100 ounces

x + (4x) = 100

Combine like-terms.

5x = 100

x = 20

Now that we know the value of x, we can figure out how many ounces of strawberry juice and how many ounces of water Molly needs.

Since x = The number of ounces of strawberry juice, Molly needs to use 20 ounces of strawberry juice.

Since y = The number of ounces of water, Molly needs to use 80 ounces of strawberry juice. (y = 4x | x = 20 | y = 4(20) | y = 80)

~Hope this helps!~

David's phone bill each month is $30. He is also charged $0.10 per GB of data he uses. If his phone bill in July was $42, how ma
Aleonysh [2.5K]

Answer:

120

Step-by-step explanation:

Okay so the equation would be like this
30 + 0.10g = P

g = GB of data used

P = Total Price

Let's work this out now!

So. If his total bill was $42 lets subtract the 30 that comes out every month automatically, now we are just left with 12, if each GB costs 0.10 then all you would do to find out how many GB he used is do 12/0.10 (which is really just 12*10) which will get you 120

Meaning that he used 120 GB

(That's a lot!)
