Answers

Answer 1

Answer:

Answer and explanation:

To find : Write a fact family for 2, −5, and −10 ?

Solution :

A fact family is a group of math facts using the same numbers.

In the case of multiplication and division, we bring number together to get the product or divisor.

For 2, −5, and −10

The fact family are,

$2* -5=-10$

$(-10)/(-5)=2$

$(-10)/(2)=-5$

A 16 1/2 kilometer stretch of road needs repairs. Workers can repair 2 1/4 kilometer of road per week.How many weeks will it take to repair this stretch of road?

Answers

Hello,

So the total length of the road is 16.5km (decimal form). Workers can repair 2.25 per week. To get the number of weeks they need to repair the road is to divide the total with per week. The equation would be:

$16.5 / 2.25 = 7.33$

or with fraction

16 2/4 / 2 1/4 = 7 1/3

Answer: The workers would need 7.33 weeks to repair the road.

Hope this helps.

Step-by-step explanation:

Which of the following is a point slope equation of a line that passes through the points

Answers

For this case we have that the slope of a line is given by:

$m = \frac {y2-y1} {x2-x1}$

If we have the points:

$(-1,4)\n(8, -2)\nm = \frac {-2-4} {8 - (- 1)}\nm = \frac {-6} {9}\nm = - \frac {2} {3}\n$

Thus, the equation is of the form:

$y-y_ {0} = - \frac {2} {3} (x-x_ {0})$

Substituting any of the points we have:

$y-4 = - \frac {2} {3} (x - (- 1))\ny-4 = - \frac {2} {3} (x + 1)$

Answer:

Option D

Answer:

Choice D is the answer.

Step-by-step explanation:

We have given two points.

Let (x₁,y₁) = (-1,4) and (x₂,y₂) = (8,-2)

We have to find the point-slope form of the line that passes through the given points.

y-y₁ = m(x-x₁) is point-slope form of the line that passes through the points.

m is slope of line.

m = y₂-y₁ / x₂-x₁

Putting values in above formula , we have

m = -2-4 / 8-(-1)

m = -6 / 9

m = -2/3

Putting values of slope and using a point , we have

y-4 = -2/3(x-(-1))

y-4 = -2/3(x+1) is point-slope form of line that passes through the points (-1,4) and (8,-2).

What is the sum of 3 1/10 and 1 3/4 . please help me with this .

Answers

the sum is 4 and 17/20.
first, you have to create a common denominator. the least common multiple of 4 and 10 is 20, so I used that.
since 10 is multiplied by 2 to achieve, twenty, we also multiply 1 by 2, which makes 3 and 2/10
4 on the other hand, is multiplied by 5 to achieve 20, so we multiply 3 by 5 also, which is 15.
from there, we have 3 2/20 + 1 15/20, which equals 4 17/20.

The sum or 3 1/10 and 1 3/4 is 5.
