If im using equivalent expressions, and i did 7x+1, can that equal 1x+7? ?

7x+1 is the same as 1+7x. You can add in any order (eg: 2+3 = 3+2 = 5)

However, 7x+1 is not the same as 1x+7. Try replacing x with 0 for each expression. You'll find that 7x+1 turns into 1 while 1x+7 turns into 7. That is one example why 7x+1 and 1x+7 aren't equivalent.

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )
