3 divided by 2/5

you do the reciprocal of 2/5 which is now 5/2

after that you multiply 3 times the 5/2

multiply the numerators which is 3 x 5 and get 15

then multiply the denominators which is 1 x 2

you are left with 15/2 after and if you want a decimal it is 7.5

your friend claims that two isosceles triangles ABC and DEF are congruent if two corresponding sides are congruent. he explains

Svetach [21]

Think about the fact that you can have two types of isosceles triangle: one of them that is a right triangle (isosceles right triangle) such as a 45-45-90 triangle and the other type can be just a regular triangle that has two sides that are congruent but it isn't a right triangle.

Thus, you would need more info about the triangles in order to conclude that the two isosceles triangles are congruent to each other.

Find the value of r so the line that passes through the pair of points has the given slope.

SOVA2 [1]

Answer:

The missing value in the ordered pair is 66

Step-by-step explanation:

Given that:

(12,10) and (-2,r)

Slope = m = -4

We have to find the value of r so that the line has a slope of -4.

Slope is the steepness of line which is denoted by m.

Here,

$x_1=12, y_1=10\\x_2=-2, y_2=r$

Putting the values in slope of line formula,

$-4=\frac{r-10}{-2-12}\\ -4=\frac{10-r}{-14}\\$

Multiplying both sides by -14

$-4*-14=\frac{r-10}{-14}*-14\\56=r-10\\56+10=r\\66=r\\ r=66$

The value of r is 66

Hence,

The missing value in the ordered pair is 66
