Answer:

The root left box represents the expression that finds the side length x.

Answer: 21

Step-by-step explanation:

To find the missing number you set the two equations as a proportion:

[tex]\frac{7}{9} = \frac{x}{27}[/tex]

To solve for x we cross multiply:

27 × 7 = 189

9 × x = 9x

Set up an equation:

9x = 189

Divide both sides by 9:

x = 21

Answer:

Step-by-step explanation:

a. → Mary had a debt of $30. She earned $15 more now she has _x = $30 + $15_______.

b.→ A diver was at the depth of 10ft . Then he sank 5ft. then he sank 15ft more . now he is at depth of _x = 10 + 5 + 15 ft.

c.→ The temperature was 2*c and feel 7* . Then it rose 4*. Now the Temperature is _x = 2 + 4__________ *c.

Answer:

y+3 = -4(x-2)

Step-by-step explanation:

We can use point slope form since we are given a point on the line and a slope,

Point slope form is

(y-y1) = m(x-x1) where m is the slope and (x1,y1) is a point on the line

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

y+3 = -4(x-2)

Each poet reads for exactly 15 minutes.

Step-by-step explanation:

If it should run for 90 minutes, and there is 6 poets, therefore I'm pretty sure you divide 90 by 6, which is 15.

Answer:

it took him 15 min

Step-by-step explanation:

Answer:

689 minutes

Step-by-step explanation:

0.05x + 3.99 = $38.44

0.05x = 38.44 - 3.99

x = 34.45/0.05

x = 689

SSS (Side-Side-Side) only proves congruence (If three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.) So technically no, but you cant tell if there are no angles.

[tex]\triangle PQR[/tex] is not congruent to [tex]\Delta XYZ[/tex] because a non-rigid motion was performed. (Correct choice: B)

A motion is rigid if and only if the Euclidean distance between any two points of an affected geometrical figure is conserved, there are four operations considered for rigid motion:

Thus, scaling is not a rigid motion as Euclidean distances between any two points of the figure are altered. In a nutshell, [tex]\triangle PQR[/tex] is not congruent to [tex]\Delta XYZ[/tex] because a non-rigid motion was performed. (Correct choice: B)

Answer:

Patrick needs 1/2cup of flour for each batch of cookies

Answer:  Yes they are all on the same line.

Step-by-step explanation:

We can find an equation between two of the points and check to see if the third point is also a solution.  I'll pick (1,3) and (-2,4) and calculate a slope:

y = (4-3) = 1

x = -2 - 1 = -3

slope = y/x

slope = -1/3 or -0.3333

The equation, so far, is:

y = -(1/3)x + b

We can find b by entering one of these points into the equation and solving for b.  I'll pick (-2,4):

y = -(1/3)x + b

4 = -(1/3)(-2) + b

4 = (2/3) + b

b = 3 1/3 or 10/3

The equation is

y = -(1/3)x + 10/3

This equation goes through the two points we used to cacluate the slope.  The third point, (4,2) can be checked to see if the equation gives us a y value of 2 if we set x=4:

y = -(1/3)x + 10/3

y = -(1/3)*(4) + 10/3

y = -(4/3) + 10/3

y = 6/3 or 2

It correctly returns a value of 2, so (4,2) is also on this line.

Based on the distance they covered in the time they did, we can infer that Zahara's dad was driving at 53 miles per hour.

To find the speed, the following formula is used:

= Distance / Time

They travelled 159 miles in 3 hours.

Distance = 159 miles

Time = 3 hours

The speed must be:

= 159/3

= 53 miles per hour

In conclusion, he was going at 53 miles per hour.

Step-by-step explanation:

Answer:

AB = BC = AC = 15

Step-by-step explanation:

Since the triangle is equilateral then the 3 sides are congruent.

Equate any 2 sides and solve for x , that is

AC = AB , so

11x - 7 = 6x + 3 ( subtract 6x from both sides )

5x - 7 = 3 ( add 7 to both sides )

5x = 10 ( divide both sides by 5 )

x = 2

Then

AC = 11x - 7 = 11(2) - 7 = 22 - 7 = 15 , thus

AB = BC = AC = 15
