We can't solve it with that information
Answer:
x = 3
Step-by-step explanation:
Step 1: combine like terms
On the left side, you can combine 4x and 3x to get 7x and the right side is already simplified
Now we have 7x+10=40-3x
Step 2: subtract 10 from both sides
10-10 = 0 and 40-10 = 30
Now we have 7x = 30-3x
Step 3: Add 3x to both sides
7x +3x = 10x and 30-3x+3x = 30
Now we have 10x =30
Step 4: divide by 10 on both sides
10x/10 = x and 30/10= 3
Therefore, we have x =3
Answer:
32.
Step-by-step explanation:
This is an arithmetic sequence with first term a1 = -6 and common difference 2.
an = a1 + d(n - 1)
a20 = -6 + 2(20-1) = 32
This is my work. the answer would be 200 2/3.
Um... it'll take each pipe 80 mins, bcz if together they take that long, then to find the pipes time separately, you just multiply it by two to show it doing the work the other pipe did as well. Is that what you wanted??
