Answer:17
Step-by-step explanation: count 8, 17 times and that is how you get your answer
Hey there!
First solving the equation 2^3 . . .
To solve 2^3, multiply the number 2 three times:
2 x 2 x 2 = 8
To find area, multiply the two sides . . .
(Since a square has all sides the same length, multiply 8 x 8)
8 x 8 = 64 <-------
The area of the shape is 64 inches.
Hope this helps you.
Have a great day!
Okay, so there are nickels and pennies in this jar.
So, let's call the number of pennies X
Since there are 161 coins altogether, the number of nickels is (161 - X)
So now we solve the equation:
.01X + .05(161 - X) = 3.09
.01X + 8.05 - .05X = 3. 09
4.96 = .04X
124 = X
So, there are 124 pennies
Therefore, there are 161 - 124 = 37 nickels
Let's check our answer:
124 x .01 + 37x .05 = 1.24 + 1.85 = 3.09
It works!
