Write an expression for the sequence of operations described below. add 14 to s, then divide v by the result Do not simplify.

First we look for the form of answer that is requested in the problem. We need ask ourselves what are we being asked to do? There are hints that let you know how to understand this idea. (Write an expression). In general we are being asked just to change theses words into an alpha-numeric expression without actually solving. (Do not simplify). Now with that understanding we change the expression from worded operations to operational symbols with numbers like so: add 14 to s, then divide v by the result I recommend starting by placing s first change add to '+' then set it next to s like so s+14 now change divide to its symbol '/' now place it under the v with division symbol between them like this: v/s+14 this is the final answer we can stop here.

Harry walked 8 blocks from his house to the train station. He rode the train 72 blocks to the library. Later, he came home the same way. How many blocks did Manuel travel in all?

I recommend mapping and labeling the problem first. 8----72 going 72---8 coming back round trip= 8+72+8+72 Now I recommend setting up the problem mentally like so: 00+8 00+8 70+2 70+2 next I suggest adding from top to bottom going from right to left like this think 16 plus 4= 020 then think 70+70=140 then combine like this 020 +140 result 160 final answer Harry went 160 blocks in total

Solve this system of equations 8x+2y=16 8x+4y=32

Demonstrating the elimination approach: Setup like this 8x+4y=32 8x+2y=16 reduce 2 equations to 1 with subtraction 4x+2y+16 make variables zeros and solve like this 4(0)+2y=16 ; 2y=16; y=16/2 result y=8, x=0, then 4x+2(0)=16; 4x=16; x=16/8; result x=2. y=0 now check it by plugging in one answer set x=4; y=0 4(4)+2(0)=16; 16=16 system is solved or checks out with these answers
