124.48 because you can just multiply the number by two.
Answer: The scale factor is 2
(2 as a fraction is 2/1)
Gradient = rise/run = -1/2
Thus:
y = -1/2x + c
Solve for c:
Pick a point for the values of y and x
(2,-2)
-2 = -1/2 (2) + c
c = -2 + 2
c = 0
Thus the equation is
y = -1/2x
You will set it up so that the two equations are equal to each other.
2,200 * (2.31 * 10^x) = 1.05 * 10^y
Then depending on what you have learned you either plug in each value and check, or solve it mathmatically.
The steps for solving mathmatically:
Distribute the 2,200.
5082 * 22000^x = 1.05 * 10^y
Next divide both sides by 1.05
4840 * 20952.4^x = 10^y
I don't know if that is to the power of y or times y?
Answer:
67 cents
Step-by-step explanation:
2 quarters: one quarter is 25 cents, so two will be 50 cents.
5 cents: Just 5 cents.
1 dime: A dime is 10 cents.
2 cents: 2 cents!
Add everything up: 50 + 5 + 10 +2 = 67 cents!
