Jackson owes his sister Monica $15. Explain the meaning of zero in this situation.

ludmilkaskok [199]

accounting wise, if a value is positive, is an asset, you're above water, +50, you have 50 bucks in your account/pocket.

if a value is negative, is a liability, you're below water, -50, you owe 50 bucks, you're in the hole for 50 clams.

so Jackson owes Monica $15, he's in the hole for 15 bucks, namely his balance with his sister is -15.

if he pays her $1, he owes her 14, so -14 is his balance, let's make a quick table of that

pays her 1................... -14

pays her 2..................-13

pays her 3...................-12

and so on

pays her 13.................-2

pays her 15..................0

0 means, he paid her in full.

Solve for t. You must write your answer in fully simplified form. −19=7t

nikitadnepr [17]

Answer:

t=-19/7

Step-by-step explanation:

you need to isolate for t which means you need to get t all alone on one side of the equation. Do do that you can divide both sides by 7. This gives you -19/7=7t/7

we know that anything divided by itself is 1 so we get -19/7=t

This is the simplest for because 19 and 7 are both prime numbers, so you can't simplify them.

Please help 2 questions

inna [77]

Answer:

1) 2002

2) 92

Step-by-step explanation:

First, you need to find the area of the triangular base. The height of the triangle is 7, and the base is 26, meaning that the area is 7*26/2=91. Multiplying this by the length of the prism, you get 2002 cubic meters.

First, you need to find the area of the trapezoidal base. The two bases of the trapezoid have lengths 12 and 11, while the height is 8, meaning that the area is 8*(12+11)/2=92 cubic centimeters.

Hope this helps!
