They will both have the same amount in the bank after 10 weeks
<h3>What are linear equations?</h3>
Linear equations are equations that have constant average rates of change, slope or gradient
<h3>How to determine the solution to the system?</h3>
A system of linear equations is a collection of at least two linear equations.
In this case, we have
<u>Nancy</u>
Initial = 400
Rate = 10
So, the equation is
y = 400 + 10x
<u>700</u>
Initial = 700
Spending = 20
So, the equation is
y = 700 - 20x
When they both have the same amount of money in the bank, we have
700 - 20x = 400 + 10x
Evaluate the like terms
30x = 300
Divide by 30
x = 10
Hence, they will both have the same amount in the bank after 10 weeks

Volume=legnth times widht times height
since this is a rectangle and multiplication is commutative
doesn't matter what order wr multiply
V=5*5*12
V=300 in^3
Let me know if you need me to explain!
Answer:
77 and 85
Step-by-step explanation:
Since the number 6545 ends in a 5, we can assume that one of the two digit numbers ends in a 5. I tried 55, 65, 75, and 85, and I just divided 6545 by those numbers until I got a two-digit positive integer as my answer,
85 * 77 = 6545
Therefore, the answer is 85 and 77.
I hope this helps!
Answer: The height of the building = 56 feet.
Step-by-step explanation:
Let AB be the height of the building and BC be the distance of the car from the building on the ground.
Now , ∠ C = 32° [Alternate interior angles ]
According to the trigonometry,
Hence, the height of the building = 56 feet.
