8 more than the product of a number and 7 is equal to 2​

Answer:

novel = 416

short story = 32

Step-by-step explanation:

13n + n = 448

n= 32

so novel has 32x13 = 416

short story has 32

416+32 = 448

Answer:

There are 2,000 grams left after 300 years.

Step-by-step explanation:

Giving the following information:

The half-life of a radioactive substance is 200 years. There are 8000 grams of the substance initially.

First, we need to calculate the reduction of the substance each year:

Yearly reduction= 8,000/400= 20 grams per year

Now, for 300 years:

300 year reduction= 20*300= 6,000

There are 2,000 grams left after 300 years.

Answer:

2

Step-by-step explanation:

You would replace the x with -2x so you would end up with -2×-2 and that is 4 then minus 2 is 2.

Answer:

The last one.

Step-by-step explanation:

The last table because y = 5x   ( a = 5):

0 = 0*5

25 = 5*5

75 = 15*5

250 = 50 *5

Answer:

y=5/9x+5

Step-by-step explanation:

The formula is y=mx+b with m being the slope and b being the y intercept so just plug in the values.

The equation of a straight line can be written by the equation y = mx + b, where m is the slope and b is the y-intercept.

Substitute in your values:

y = 5/9x + 5

Therefore the equation of your line with the information given would be:

y = 5/9x + 5

Answer:

B 360

Step-by-step explanation:

i have Mrs. Dunn

Sum of the measures of the exterior angles of a convex 55-gon is equal to  360.

A polygon is a two-dimensional geometric figure that has a finite number of sides. The sides of a polygon are made of straight line segments connected to each other end to end. Thus, the line segments of a polygon are called sides or edges.

here, we have,

An exterior angle is an angle between a side of a polygon and an extended side adjacent to it.

A polygon refers to any closed curve comprised of a set of connected sides such that no two sides cross.

Convex 55-gon means a convex polygon with  n sides.

The sum of measures of any polygon is equal to 360

So, the sum of the measures of the exterior angles of a convex 55-gon is equal to 360.

Answer:

1/3

Step-by-step explanation:

-3 - -1= -2

3-9 = -6

-2/-6 = 2/6 = 1/3

Answer: 1/3

Step-by-step explanation:

slope = change in y / change in x

= (-3 - -1) / (3 - 9)

= -2 / -6

= 2/6

Answer:

6$ a week or 12$ Every 2 weeks

Step-by-step explanation:

Step-by-step explanation:

Not entirely sure, but I believe something like this:

∠1 + ∠2 = 180° since they are a linear pair;

Since ∠1  = ∠2, we can say:

∠1 + ∠1 = 180°

2(∠1) = 180°

∠1 = 90°

And since:

∠1 = ∠2

∠2 = 90°

So the angle between t and s is 90°;

An angle of 90° means t and s are perpendicular (⊥)

Answer:

a=9.8

Step-by-step explanation:

a(2)+2(2)=10(2)

2×2=4 10×10=100

subtract 4 from 4 and 100

a(2)=9.6

use the two buttons on the scientific caculator. Click 2nd, then click x2(close to bottom left)

you will get a bunch of numbers only put down the first 3. (9.79)

ROUND THIS

9.79=9.8

a=9.8
