Solve for the variable 7/28 = 25/?

1 answer:

7 0

Let x be the unknown number. The equation is going to be 7/28=25/x, now we cross multiply. 7*x=25*28, 7x=700, divide both sides by 7 and you should get 100, So, x=100 and 7/28=25/100

Answer asap what is the slope of a line that contains the points (-1,6) and (1,4)? [

Otrada [13]

Answer: -1

Step-by-step explanation:

In order to find the slope, you should remember the formula (Y1-Y2)/(X1-X2) the order of the x and ys do not really matter, but the they should be the same for the top and bottom. In this situation, you can do (4-6) which represent your Y1 and Y2 and then divide by (1 minus -1) which are your xs, this simplifies to -2/2 or simply, a slope of -1

Humood's house is (-5,7)

grin007 [14]

The distance from Humood's house to the school is 500m

<h3>How to determine the distance from Humood's house to the school?</h3>

The given parameters are:

Humood's house is (-5,7)

The school is (3,1)

The distance between both points is calculated using

$d = \sqrt{(x_2- x_1)^2 + (y_2 - y_1)^2$

Substitute the known values in the above equation

$d = \sqrt{(-5 - 3)^2 + (7 - 1)^2$

Evaluate

d = 10

Each unit in the graph is 50m.

So, we have

Distance =10 * 50m

Evaluate the product

Distance = 500m

Hence, the distance from Humood's house to the school is 500m
