Answer:
Lets say test tubes = t, and beakers = b
1 pack of (t) is $4 less than 1 pack of (b)
Since i have no prior information we are going to use variables for this equation:
1t (1 pack of test tubes) is $4 less than 1b (1 set of beakers)
so to quantify the equation, we have 8t and 12b.
if b is a number that IS quantifiable such as $5 we can easily figure out this answer.
Lets use and example that 1 set of beakers is $8, if we multiply $8 by 12 (the number of sets of beakers), we get: 96
Using the same example, if 1t is $4 less than 1b than 1t = $4. So, if we multiply $4 by 8 (the amount of packs of test tubes), we get: 32
If you take both of those numbers: 96, and 32 and you divide them you get 3. so that means that 1t = 3b
Answer = 1t = 3b
This may not be correct due to the little information that i got however i hope that, that works out for you :)
192 possible plain sandwiches can be made because you would do 4x6x8 which equals 192.
(-2/3, 2)
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Answer:
1st Equation: 0.95 x 15 answer if needed: 14.25
2nd Equation: 15 - 0.25 answer if needed: 14.25
Step-by-step explanation:
1st: 100% would be 1, so subtract 0.05 (5%) from that to get 0.95 (95%), then multiply that by the total amount of money (undiscounted)
2nd: Find the original price. Get the the discount percentage. Calculate the savings. Subtract the savings from the original price to get the sale price
