Step-by-step explanation:
5m=500cm
Area=length x length
500m x 50cm=25000cm^2
OR
250m^2
Answer:
There are 23 dimes in the box
Step-by-step explanation:
Let nickels=n
Let dimes=(35-n)
Equation: 0.05n+0.10(35-n)=2.90
Multiply both sides by 100: 5n+10(35-n)=290
-5n+350=290
-5n=-60
n=12
35-12=23
Therefore, there are 23 dimes in the box
Answer:
Step-by-step explanation:
Equation 1
Let's solve for x
3x -5y = -5
Step 1: add 5y to both sides.
3x - 5y + 5y = -5 + 5y
3x = 5y - 5
Step 2: Divide both sides by 3
3x divide by 3 = 5y - 5 divide by 3
x = 5/3y + -5/3
Answer:
x = 5/3y + -5/3
Answer:
7.3
Step-by-step explanation:
time is distance divided by velocity/speed
t = 220/30
t = 7.33333 = 7.3
Answer:
(-3, 1)
The solution is the point at which both lines intersect.
This is the solution since both lines would have that point and only that ppoint in this type of problem. IN a graph where 2 lines are parralel, there is no solution as they never intersect . on a graph where the 2 lines overlap there is infinite solutions. FInally in a graph like this there is exactly one solution and it is the intersection of both lines
