Adisk costs 3 more then a tape role bought five disks and two tapes. the total cost was 120

5(x+3)+2x=120
5x+15+2x=120
7x+15=120
7x=105
x=15
Tape cost $15 disks cost $18

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
