Answer:
343
Step-by-step explanation:
There are quarters(25¢), loonies ($1), and toonies ($2)
And total number of coins is 9
If loonies ($1), and toonies ($2) are one, then quarters(25¢) is 7
If quarters(25¢), and toonies ($2) are one, then loonies ($1)is 7
If loonies ($1), and quarters(25¢) are one, then toonies ($2) is 7
So possible number number of combination for an item that cost between $10 and $12 is
= 1^3 * 1^3 * 7^3
= 343
hope this helps, stay safe :)
X/3 - 38 = 42
x/3 = 80
x = 240
Depends.
A. -12 - -6 = -6
but
B. -6 - -12 = 6
Two negatives always cancel, so the equation for A. would be like saying
-12+6, and B. -6+12.
Answer:
The first choice is the one you want
Step-by-step explanation:
Use geometric means to solve for a first. The formula is
and 64 = 15a and a = 64/15
That one was quite easy. Finding b is a bit more difficult.
The formula for finding b is
Solving for b:
Filling in we have
and
and
so b = 136/15
156÷13
13 goes into 15 once
so under the 156 put 13 under 15 left with 2 bring down the 6 to make it 26
13 goes into 26 2 times
so under where you wrote 26 put 26 then 26-26=0
so your answer is 12
