1quart=2pints
convert 2 points to quarts
2 quarts=2 times 2 pints=4 pints
now we have
4pints>10pints
false since 4>10
FALSE
Add 2x and subtract 7
5 -2x +2x < 7 +2x . . . . . . showing 2x added
5 < 7 +2x . . . . . . . . . . . .. simplified
5 -7 < 7 -7 +2x . . . . . . . . showing 7 subtracted
-2 < 2x . . . . . . . . . . . . . . . simplified
Now, divide by 2
-1 < x
The solution is -1 < x.
Divide top and bottom by 2= 7/1
Multiply top and bottom by 3. 21/3
Multiply top and bottom by 4 = 28/4
Answer- b+t=90 (or bb + tt = 90 ignore if this was a mistake)
If we know that 90 is an absolute total, that will go behind the equal sign
?=90;
We know that we can make any mixture of burritos or tacos, but they have to equal up to ninety. As you stated bb= burritos and tt= tacos. (If that is a mistake, instead of putting bb or tt, just put the single letter b or t)
This means our equation would have to have a certain number times burritos and a certain number times tacos that equal 90.
Our equation should look a little like this
(number of burritos ) + (number of tacos) = 90
b + t =90 or with your values bb+tt=90
HOPE THIS HELPS & GOOD LUCK

<u>2. What is P(M), the probability that a student plans to major in mathematics?</u>
- P(M) = number of students who plan to major in mathematics / number of students
