Answer:
X = -2
y = 2
Step-by-step explanation:
Substitute y=x + 4 in the second equation to find x
x+4 = 2x + 6
subtract x from both sides
4 = x + 6
subtract 6 from both sides
-2 = x
put -2 in for x in the first equation
y= 2
Problem: 2/7 (4+c)=6
1. 7/2 x 2/7 x (4+c)=7/2 x 6
2. 4+c=7 x 3
3. 4+c=21
4. c=21-4
Answer: c=17
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.
Answer:
$6,250
Step-by-step explanation:
5% of 5000 = .05 x 5000 = 250 this finds the amount gained per year
250 x 5 = 1,250 this is the amount earned over 5 years
5000 + 1250 = 6,250 this is the total after 5 years.
Hope this helps!
