Joe has $4 more than hector. hector has $8 more than tami. if tami has $x, write an expression for the amount of money joe has.

The answer to your question should be ($x +$8) + $4

Step-by-step explanation:

First of all ignore the dollar sign. It’s irrelevant to the problem and we aren’t dealing with decimals. First of all, we know that Hector has $8 more than Tami and Joe has $4 more than Hector so first we need to find how much money Hector has. Since Hector has $8 more than Tami and we know that Tami has $x we $x+$8 is Hectors amount of money. Since Joe has $4 more than Hector and we know Hectors money is $x + $8 Joe’s money is ($x+$8) + $4.

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
