Answer:

No she will not save enough money for her trip and she needs $122 more for her trip.

Step-by-step explanation:

Deborah requires $74 each day for 13 days trip

Total least amount needed for the trip = 74*13

                                                       = $962

Deborah's saving strategy : she saves $84 per month for 10 months

saved amount at the end of the 10th month = 84*10 = $840

840/10 = $84

This clearly shows she is not saving enough money for her trip. She needs $122 more to support the expense of her trip.

Timothy way

84*10= $840 is to be compared with 74*18 = $1332

This method is also not a feasible one for calculating Deborah's expenses of her trip.

It always seems to rain on the day after July 4th.
Rina8888 [55]

Answer:

The inductive reasoning is based on A: a limited number of observations

Step-by-step explanation:

Let's say you lived until 90 years old, and took a observation on July 4th each year. Even if you lived until 90 years old, you would only have 90 observations. And inductive reasoning allows for statements to be false, so any of the 90 observations that you took can be proven false. So really, you would have only 90 observations, with any of them that could be false. A limited number of observations would be the only thing that you could base this reasoning off of.

The right answer is Option A:x=\frac{rs-t}{2}

Step-by-step explanation:

Given expression is;

s=\frac{2x+t}{r}

We will solve this expression for x, therefore,

Multiplying both sides by r

r*s=\frac{2x+t}{r}*r\\rs=2x+t

Subtracting t from both sides

rs-t=2x+t-t\\rs-t=2x\\2x=rs-t

Dividing both sides by 2

\frac{2x}{2}=\frac{rs-t}{2}\\x=\frac{rs-t}{2}

The right answer is Option A:x=\frac{rs-t}{2}

What is the equation, in point-slope form, for a line that goes through (8, −4) and has a slope of −5/6 ?
horrorfan [7]

Point-slope form, y-y1 = m(x-x1)

(y-(-4)) = -5/6 (x-8)

y+4 = -5x/6+20/3

y = -5x/6+20/3 - 4

y = -5x/6 + 8/3
