Answer:
I think it would be 55+8x. I hope this helps. :)
Step-by-step explanation:
55 gallons of water
8 gallons per minute
It would be 55 gallons (the original amount in the tank) plus 8 gallons per minute. (8x)
x = how many minutes the tank is being filled up more.
so if you were to fill up the tank another 5 minutes, the equation would be 55+8(5)
55+40
95 would be the answer.
Answer:
x = -7
, y = 5 thus D)
Step-by-step explanation:
Solve the following system:
{4 x - 4 y = -48 | (equation 1)
5 x - 6 y = -65 | (equation 2)
Swap equation 1 with equation 2:
{5 x - 6 y = -65 | (equation 1)
4 x - 4 y = -48 | (equation 2)
Subtract 4/5 × (equation 1) from equation 2:
{5 x - 6 y = -65 | (equation 1)
0 x+(4 y)/5 = 4 | (equation 2)
Multiply equation 2 by 5/4:
{5 x - 6 y = -65 | (equation 1)
0 x+y = 5 | (equation 2)
Add 6 × (equation 2) to equation 1:
{5 x+0 y = -35 | (equation 1)
0 x+y = 5 | (equation 2)
Divide equation 1 by 5:
{x+0 y = -7 | (equation 1)
0 x+y = 5 | (equation 2)
Collect results:
Answer: {x = -7
, y = 5
If jim wants to buy a new computer he will have to work 20 months.
60 x 19 = 1,140 means he worked 19 months but he doesnt have enough money so if he works 1 more month then he will have enough.
<u>60 x 20 = 1,200</u>

Step-by-step explanation:
as much as I would like to, I'm really not that good at explaining things
Answer:
Step-by-step explanation:
a/7+b
You simply have to use the values provided in the equation given. If a=49 and b=7 you have
49/7+7, since 49/7=7 you have
7+7 which equals
