19) 7x - 8(-x+7)=-16+ 7x


Can someone help me solve this problem and also tell me what type of problem this is ?

Answer:

x = 128 degrees

Step-by-step explanation:

So we know that a triangle's interior angles should add up to 180 degrees.

We also know that when a triangle has that little square in a corner, that corner is equal to 90 degrees.

With these clues, we can figure out that the last interior angle is equal to:

180 - (38+90) = 52, however this isn't the answer we are looking for.

We also know that a straight line is 180 degrees. Therefore, to find the exterior angle we just subtract the interior angle from 180 degrees:

180 - 52 = 128

x = 128

32.4 miles in 6 days.

Step-by-step explanation-

Fran runs 5.4 miles a day.

How far will he run in 6 days.

Multiply using the formula

[tex]d = s \times t[/tex]

So, multiply:-

[tex]5.4 \times 6[/tex]

[tex] => \: 32.4 \: miles[/tex]

Therefore, he ran 32.4 miles in 6 days.

Step-by-step explanation:

y=-5x-44

Step-by-step explanation:

5x+y=13 passes through (15,31)

rearrange the equation to y=mx+c

5x+y=13

y=-5x+13

substitute the points (15,31)

y=5x+c

31=5(15)+c

31=75+c

-44=c

y=-5x-44

Can be written as 5x+y=-44

Answer:

(2, -3)

Step-by-step explanation:

Your answer was in the question, just apply the rule that was given (x, -y).

The coordinates of C(2, -3).

A reflection is a type of transformation that involves flipping a shape, known as the preimage, across a line, known as the line of reflection, to produce a new shape (called the image). You can picture what would happen if you turned the form across the line to graph a reflection.

Reflection is a type of transformation that flips a shape along a line of reflection, also known as a mirror line, such that each point is at the same distance from the mirror line as its mirrored point.

Given:

The Rule for reflection is  (x,y) =(x,-y).

As, the coordinates C(2, 3).

Now, after applying the reflection the coordinate of C become

c(2, 3) ----> C(2, -3).

Hence, the coordinates of C(2, -3).

Answer:

  15.7°

Step-by-step explanation:

The law of cosines can be used to find side s:

  s² = r² +q² -2rq·cos(S)

  s² = 8² +9.4² -2(8)(9.4)·cos(151°) ≈ 283.903

  s ≈ 16.849

Then the law of sines can be used to find angle Q.

  sin(Q)/q = sin(S)/s

  sin(Q) = (q/s)sin(S)

  Q = arcsin(q/s·sin(S)) = arcsin(9.4/16.849·sin(151°)) ≈ 15.692°

Angle Q is about 15.7°.

Answer:

x = 113, y = 67

Step-by-step explanation:

y and 67 are vertically opposite angles.

Vertically opposite angles are equal.

y = 67

x and 67 are linear pair angles.

Sum of linear pair angles is 180,

x + 67 = 180

x = 180 - 67

x = 113

The answer is option B!

Step-by-step explanation:

Answer:

B.

Step-by-step explanation:

The result if the inequality expressions are v ≥ 10 and v < 0

Given the following inequality expression

7v- 5 ≥ 65 or -3v - 2 ≥ -2

Solve the inequality individually

7v - 5 ≥ 65

Add 5 to both sides

7v - 5 + 5 ≥ 65 +5

7v ≥ 70

v ≥ 70/7

v ≥ 10

For the inequality-3v - 2 ≥ -2

Add 2 to both sides

-3v - 2 + 2≥ -2 + 2

-3v ≥ 0

v < 0

Hence the result if the inequality expressions are v ≥ 10 and v < 0

Answer:

Midpoint = (1,2)

Step-by-step explanation:

Using coordinates: D(-2,3) and L(4,1)

Using the midpoint formula:

Midpoint of DL = (D1 + L1) / 2, (D2 + L2) / 2

Midpoint of DL = (-2 + 4) / 2, (3 + 1) / 2

Midpoint of DL = (2) / 2, (4) / 2

Therefore the midpoint of DL is (1,2)

Answer:

100% - 15 % = 85 %

So, $21.08 represents the 85% sale price

What number represents the other 15% of the original price?

(21.08 x 15) / 85 = 3. 72

$21.08 + $3.72 = $24.80 which is the original price.
