<u>Answer</u>

18) $51

19)  $24

20) <em> Carla's account. </em>

<u>Explanation</u>

18)

Positive sign values means deposit while the negative values means money been withdrawn from the account.

$100 - $18 + $22 - $53 = $51

19)

Positive sign values means money deposited while the negative values means money been withdrawn from the account.

$45 - $17 - $22 + $18 = $24

20)

To get the person with the most deduction, you should add the negative values in the table then compare.

Carla ⇒ -18 + -53 = $-71

Leta ⇒ -17+ -22 = $-39

From here we can see that the account with greatest decrease is<em> Carla's account. </em>

I Need to know a or b is the answer to this question
grandymaker [24]

Answer:

A

Step-by-step explanation:

in option B, you are adding the 3 pound plastic box to each cardboard box

in option A, you have 5 separate carboard packages, and one 3 pound plastic box

This [option a] is the diagram that matches the scenario given.

Think of the x's as normal numbers. Let's say the weight of each "x" is 1. [it's not I'm aware that this question is different]

if you have 5 x's, you have

1 1 1 1 1 3

<em>not </em>1+3 ; 1+3 ; 1+3 ; 1+3 ; 1+3

you would only have this if you were to add a 3 pound plastic box to each individual package

Sub for each other since both equals y
2x-3=y=2x+5
2x-3=2x+5
minus 2x oth sides
-3=5
false

no solution
(we can see that since slopes are same and y intercepts are differnt, the lines are paralell and therfor never intersect)

The air force plane travelled for a total of 6.9 hours.

<u>SOLUTION: </u>

Given, An Air Force plane left Nairobi and flew west at an average speed of 159 mph.  A cargo plane left sometime later flying in the same direction at an average speed of 207 mph.  After flying for 5.3 hours the cargo plane caught up with the Air Force plane.  

We have to find the number of hours the Air Force plane flew before the cargo plane caught up.

Now, we know that, \text { distance travelled }=\text { speed } \times \text { time }

For air force plane \rightarrow \text { distance travelled }=159 \mathrm{x} \text { time taken by air force plane }

\text { For cargo plane } \rightarrow \text { distance travelled }=207 \times 5.3 \text { hours }

Now, when cargo plane caught the air force plane the distance travelled by the planes will be equal.

So, 159 \times \text { time taken by air force plane }=207 \times 5.3

\Rightarrow =\frac{207 \times 5.3}{159}

\Rightarrow =\frac{1097.1}{159}

Time taken by air force plane = 6.9  hrs
