Answer:
<em>x = -10, and y = -1</em>
Step-by-step explanation:
5x - 2y = -48
2x + 3y = -23
First equation times -2: -10x + 4y = 96
Second equation times 5: 10x + 15y = -115
Add the last two equations: 19y = -19
y = -1
Substitute 1 for y in the first original equation.
5x - 2y = -48
5x - 2(-1) = -48
5x + 2 = -48
5x = -50
x = -10
Solution: x = -10, and y = -1
If you're talking about 607 without decimals, then 0. Because 607 is greater than 48.
Answer:
Im pretty sure its 0.2
Step-by-step explanation:
The equation to find the length of the longer piece is
x- 12 = 55
Step-by-step explanation:
- A carpenter had two pieces of lumber that totaled in length = 55 feet
- The shorter piece than the longer piece has length of which is = 12 feet
- The longer piece is denoted as= x
- Find x = ?
- The equation can be formed to find the value of x as,
- Longer piece (x) ₋ shorter piece (12) = total length (55)
- Therefore, x ₋ 12 = 55
- the above equation states that
- if you subtract the shorter piece from the total length of the you will get the length of the longer piece.
- therefore,
- if you shift the value of shorter length on the right hand side, you can find the value of x
- so, x= 55 ₋ 12
- value of x = 43
- therefore, the length of the longer piece is 43 feet long.
Alright, we can turn the word problem at the beginning into an equation.
Let's represent oregano with "o" and peppercorns as "p".
o=p+17
Also, we know that the two added together are 253 pounds.
o+p=253
Since we know that o=p+17, let's substitute it into the second equation.
(p+17)+p=253
2p+17=253
-17 -17
2p=236
p=118
So, we have 118 pounds of peppercorns. (Although it's irrelevant to the second half of the equation, we also know we have 135 pounds of oregano)
Now, let's convert pounds to ounces.
1 pound = 16 ounces.
So, multiply 118 by 16....
118*16=1888
So, you can make 1888 one-ounce bags of peppercorns.
