4p+6=t
2(2p+3)=t
t/4 - 3/2=p
t is the total number of pens and pencils.
<span>How did the equation 2t + 16 ≤ 30 came about?
The left side of the equation, 2t + 16, represents Alex's expenses. 16 stands for the admission and lunch ( 8+8 = 16) and 2t stands for 't' tickets times 2, since each costs $2. The right side of the equation is the limit expense which is equal to 30. Lastly, the inequality stands for 'less than or equal to'. Solving the equation,
2t </= 30 - 16
2t </= 14
t </= 7
This means that Alex should only get less than or equal to 7 tickets. Particularly, Alex is only limited to 7 tickets. The answer is letter B.</span>
Uh.... 45 plus 45 equals 90, then add 45 = 135
There is 16 ounces in a pound so you would do 6 x 4 which equals 24 days or mornings it would take to use the 6 pounds
It's all in simplest form<span />
