Convert the fraction<span> to a decimal number. The </span>fraction<span> bar between the top number (numerator) and the bottom number (denominator) means "divided by." So converting a </span>fraction <span>such as 1/4 to a decimal means you need to solve the math: 1 divided by 4.
i hope i helped

1. x = 3, y = 2
2. x = -99/68, y = -14/17
3. x = -4, y = 1
4. x = 1, y = 5
5. x = -1, y = 0
6. x = 2, y = -3
7. x = 14, y = 20
I attached the pictures with the work.
The answer is
<span>2 x minus 20 divided by 3 = 2x
equivalent of </span><span>
</span>(2 x -20) / 3 = 2x
for solving it, <span><span>(2 x -20) = 2x . (3) is sufficient
</span> </span>
so <span>2 x -20 = 6x </span><span> -20 = 6x - </span><span>2 x and -20 = 4x so x = -5</span>
Answer:
77.5
Step-by-step explanation:
For 0.30 for the first 50, just subtract 50 from 175, that leaves 125.
(An easy way to do this is think of quarters, 25+25=50 and 50+25=75 so all you have to do is subtract two 25s and you know it's 125)
Put the 125 to the side, and multiply 50 to 0.30, you get 15.
Then for 0.50 over 50 containers, multiply the remaining 125 with 0.50, you get 62.5.
Add 62.5 and 15 together, that gives you 77.5
