Rodney decides to pay a $200 fee in 3
payments. The first payment is 10% of the
original fee. The second payment is 25% of the
original fee. Which expressions represent the
amount of money for the third payment?

Answers

Answer:

65% of the orginal fee or $130.

Step-by-step explanation:

You didn't put the answer options so I am not sure how you want the question to be answered. There are three ways I would write it:

1:  100% = 10% + 25% + 65%

2:  200 = 20 + 50 + 130

3:  200 = (0.1 x 200) + (0.25 x 200) + (0.65 x 200)

All of them basically mean the same thing it is just a matter of how you need it written.

Based on the amount to be paid and the percentage paid in each installment, the expression for the third payment is 65% x 200.

Rodney has to pay $200 in three installments.

The third installment will be:

= Percentage in total - Percentages paid already

= 100% - 10% - 25%

= 65%

The third installment is therefore:

= Percentage to be paid x Amount

= 65% x 200

Answer:

B. ∠EAB and ∠CAD;

D. ∠CAB and ∠DAE

Step-by-step explanation:

Vertical angles are two angles formed directly opposite each other when two straight lines crosses or intercepts each other. Vertical angles are of equal measure to each other.

Thus, from the diagram given,

<CAD is vertically opposite to <EAB, also,

<CAB is vertically opposite to <DAE.

Thus, the vertical angles are:

Answer: (x-6)(x+1)

Step-by-step explanation:

Sum :  x2 − 5  x- 6

x2 + x-=6 x − 6

factor pair: x  2 + x − 6 x − 6

x( x+ 1 ) − 6 ( x + 1 )

rewrite from: x (x  + 1 ) − 6 ( x + 1 )

(x-6)(x+1)

Answer:

A: (x-6)(x+1)

Step-by-step explanation:

We need to find 2 numbers that add to make -5 and multiply to make -6.

We already have the numbers infront of us, so by process of elimination we can remove B and D.

For the numbers, we need a positive number and a negative number (two negatives make a positive). We can eliminate C because at first -3 multiplied by 2 is -6. However, when -3 is added to 2 we get -1.

If we expand A, it makes the expression that needs to be factorised because...

-6 × 1 = -6

-6 + 1 = -5

So expanding it properly we get.

x² - 6x + x - 6

Simplify.

x² - 5x -6
