Answer:
You can use multiplication to check your division answer this way.
Do the division problem.
Multiply the quotient times the divisor.
If there is a remainder, add it to the multiplication product.
Compare this answer to the dividend. They should be the same number (630 = 630).

The errors are that she is just multiplying incorrectly.
10* 1.75 = 17.5
100* 1.75= 175
1000* 1.75 = 1750
When you are multiplying by tens (hundreds and thousands are also considered tens since they are just 10*10 and 10*10*10), you should just be moving the decimal place forward one place.
This goes back to very basic math when you are learning place values.

Answer:
-3 and -4
Step-by-step explanation:
f(x) = g(x) will be the input or x value at which f and g have the same output or y value. Look in the table where two numbers repeat right next to each other.
−6 −4 1
−5 0 2
−4 4 4
−3 8 8
−2 12 16
−1 16 32
0 20 64
The solution to f(x)=g(x) is both x = -4 and x=-3.
Answer:
a) $525 CAD
b) $168.30 per day
c) $38.05
Step-by-step explanation:
a) <u> 1 USD </u> = <u> 500 </u>
1.05CAD x
cross-multiply: x = $525 CAD
b) 504.90 / 3 = 168.30 per day
c) <u> 1 USD </u> = <u> x </u>
1.05CAD 39.95
cross-multiply: 1.05x = 39.95
x = 39.95 / 1.05
x = $38.05 USD
