At her birthday party, Marcie's guests ate 2/3
of her birthday cake, and her family ate 1/4
of the cake. How much cake was left after her party?
To find how much cake was left after the party, we need to subtract the portions eaten from the total cake.
Marcie's guests ate 2/3 of the cake, so the portion left is 1 - 2/3 = 1/3 of the total cake.
Marcie's family ate 1/4 of the cake, so the remaining portion is 1/3 - 1/4 = (4/12) - (3/12) = 1/12 of the total cake.
Therefore, 1/12 of the cake was left after the party.
Mary has $500 in her account. She makes a $350 withdrawal, deposits $100, and then gets charged a $20 fee. How much does she have in her account?
Responses
Mary's initial amount in her account is $500.
After making a $350 withdrawal, she has $500 - $350 = $150 left.
After depositing $100, she now has $150 + $100 = $250.
After being charged a $20 fee, she now has $250 - $20 = $230.
Therefore, Mary has $230 in her account.
On a given morning the temperature was 71°F. The temperature dropped 5°F and then rose 8°F. How much does the temperature need to rise or fall to return to the initial temperature of 71°F?
The temperature initially was 71°F.
It dropped 5°F, so the temperature became 71°F - 5°F = 66°F.
Then, it rose 8°F, so the temperature became 66°F + 8°F = 74°F.
To return to the initial temperature of 71°F, the temperature needs to drop 74°F - 71°F = 3°F.
Therefore, the temperature needs to drop by 3°F to return to the initial temperature of 71°F.
-14.25 + -3.78 - (-5.78) - 3.4
-14.25 + -3.78 - (-5.78) - 3.4 equals -14.25 + (-3.78) + 5.78 - 3.4.
Combining like terms, this becomes -14.25 - 3.78 + 5.78 - 3.4.
-14.25 - 3.78 equals -18.03.
5.78 - 3.4 equals 2.38.
So, -14.25 - 3.78 + 5.78 - 3.4 becomes -18.03 + 2.38.
Finally, -18.03 + 2.38 equals -15.65.
Therefore, -14.25 + -3.78 - (-5.78) - 3.4 equals -15.65.
