The answer is yes. I already answered this lol
Answer:
x = 3/8
Step-by-step explanation:
There are two ways you can do this. You can use the longer way:
15+16+17+18+19+20+21+22+23+24 = 195 (starting from the top row, which has 15 logs, up until the bottom row, which has 24 logs, on condition that each second row has one log more than the previous one)
You can also use the formula (where n is the number of rows)
x= (n(first term+last term))/2
x= (10(15+24))/2
x= (10*39)/2
x=390/2
x=195
Either way, there are 195 logs in the stack.
Answer:
The values of x and y to the given equations are x=-1 and 
The solution is (-1,
)
Step-by-step explanation:
Given equations are 
and 
to solve the given equations by elimination method :
Adding the given two equations (1) and (2) we get


_______________
4x=-4

Therefore x=-1
Now substitute the value x=-1 in equation(1) we get
(-1)+3y=9
3y=9+1

Therefore the values of x and y to the given equations are x=-1 and 
The solution is (-1,
