Answer:

13 1/8

Step-by-step explanation:

We need to change the mixed number 5 1/4 to an improper fraction

5 1/4 = (4*5+1)/4 = 21/4

5 1/4 ÷ 2/5

21/4 ÷ 2/5

Copy dot flip

21/4 * 5/2

105 / 8

We need to change this back to a mixed number

8 goes into 105 13 times (13*8 =104) with 1 left over

13 1/8

Someone please help me. I will give you hella points I need this answer to like graduate type

PtichkaEL [24]

Answer:

$9 and $7

Step-by-step explanation:

The first equation:

x + 2y = 23

The second equation:

2x + 3y = 39

Convert to slope-intercept form:

x + 2y = 23 ⇒ 2y = -x + 23 ⇒ y = -1/2x + 11.5
2x + 3y = 39 ⇒ 3y = -2x + 39 ⇒ y = -2/3x + 13

The graph is attached

Intersection point is (9, 7)

An isosceles triangle has (5 points) A, at least two congruent sides B. two sides that are perpendicular C. three sides with the

aev [14]

Answer:

A. at least two congruent sides

Step-by-step explanation:

Since, we know that,

'An isosceles triangle is a triangle having two sides of equal length or at least two sides of equal length (special case is equilateral triangle)'.

Thus, from the options, we see that,

Options B, C and D are not correct.

Since, congruent sides means that the lengths of the sides are equal.

Thus, we get that,

'An isosceles triangle has at least two congruent sides'.

Hence, option A is correct.

Find the coordinates of the third vertex that completes the construction of a right triangle on the coordinate plane.

Neko [114]

Answer:

(7,a) Where a ∈ R - {7}

OR

(-2,a) where a ∈ R - {-2}

Step-by-step explanation:

The coordinates of the given line from the right to the left are:

(7,1) and (-2,1)

So, to make a right triangle, we need to make a right angle or by another words, we need to a make a perpendicular line to the given line (i.e: a vertical line parallel to the y-axis at one of the given points)

So, the third vertex must be on the line x=7 or x=-2

So, the coordinates of the third vertex is:

(7,a) Where a ∈ R - {7}

OR

(-2,a) where a ∈ R - {-2}
