120 square centimeters i think?
3(a+b) and 3a+b: not equivalent
4(x+2y) and 8y+4x: equivalent
Answer:
D
Step-by-step explanation:
speed = space/time
24/4.3 = 5.6 ft/s
To find a percent of a number, multiply the percent by the number.
First we find the number of pennies.
40% of 220 =
= 40% * 220
= 0.4 * 220
= 88
88 coins are pennies.
220 - 88 = 132
132 coins are not pennies.
Now we find 25% of 132.
25% of 132 =
= 25% * 132
= 0.25 * 132
= 33
33 coins are partners.
(Did you mean quarters instead of partners?)
