2(5*4)+2(4*3)+2(3*5)=94 sq.m (Orginial SA)
2(4*5)+2(5*6)+2(6*4)=148 sq.m (Total SA)
148-94=54 (New SA)

Given that :-
→ N represent the number of bikes .
→ Weight of container including bikes is 250+23(n-1) pounds.
To Find :-
→ Weight of container when we have 20 bikes.
Solution :-
→ Weight = 250+23(n-1) pounds
Putting the value of n here .
→ Weight = 250+23(20-1)
→ Weight = 250 +23(19)
→ Weight = 250 + 437
- → Weight of container is 687 pounds.
Since there is three feet in a yard you multiple 450 by 3 which equals 1350 then you multiple that by two because you multiplying the time by 2 which equals 2700.
Answer:
(4,-5)
Step-by-step explanation:
Hi there!
The problem asks us to solve by elimination, where we will add the two equations together to clear one variable, solve for the other variable, and then substitute the value of the other variable to find the value of the first variable
here's the system:
4x-9y=61
10x+3y=25
we'll clear y to start
multiply the second equation by 3
3(10x+3y)=3(25)
30x+9y=75
4x-9y=61
now add the equations together (the 9y's clear because one is positive and another is negative)
34x=136
divide by 34
x=4
the value of x is 4
now to find y:
substitute the value of x into either one of the equations to solve for y
if we were to do the first equation for example:
substitute x as 4 into the equation
4(4)-9y=61
multiply
16-9y=61
subtract
-9y=45
divide
y=-5
so the answer is x=4, y=-5. If you need it as a point, it's (4,-5)
Hope this helps! :D
