Pre algebra (8th grade math) 2 questions double the points

11.)

We can let the scores we don't know by x, and we know that tokay had 14 more points than Lodi. This can be shown as the following:

x + (x+14) = 162

2x+14=162

162-14= 148

148/2 = 74

Therefore Lodi scored 74 points.

12.)

We can substitute the prices we don't know by x and have the following:

4x+x=6.50

5x=6.50

6.50/5= 1.3

4x1.3= 5.2

Therefore the sandwich cost $5.20 and the drink costs $1.30

Tokay high school scored(148pts)

Step-by-step explanation: 162= T+14   162= T + 14  this is the first step            

                                              -14      -14    because 162 is total T is the

                                               148=T         unknown and 14 is our next number.

Tokay=T                                                          

Lodi=14                                                next step you subtract 14 from both sides.

Total=162

                                                      So then your left with 162 being equal to 148

                                                      So Tokay scored 148 points.

it would open into a square depending on the type of envelope i’m not sure about the second part
