If ya'll could help me with this one, it would be highly appreciated :]

Answer:

6.5

Step-by-step explanation:

Im not 100% sure because I may have overcomplicated this but im going to submit this anyway.

I'll do part (a) to get you started.

The angle 'a' pairs up with the 123 degree angle as a corresponding angle pair. Due to the parallel lines, the corresponding angles are congruent. Therefore a = 123.

We also see that b = 123 as well since a = b (they are vertical angles).

Notice how angle c is adjacent to the 123 degree angle. These two angles form a straight line, so they must add to 180 degrees.

c+123 = 180

c = 180-123

c = 57

-------------------------

To summarize, we have these three angles

a = 123

b = 123

c = 57

Answer:

a)      a=57°    b=123°   c=123°

b)     f=98°  d=98°   e=98°

c)     g=75°    h=75°

Step-by-step explanation:

a) a°+123°=180°  (angle on a straight line=180°)

    a°=180°-123°

     a°=57°

  b°=123°  (alternative angles)

  c=123°   (vertically opposite angles are equal)

b)f+82°=180°  (angle on a straight line=180°)

   f=180°-82°

   f=98°

  f=d (corresponding angles are equal)

   d=e  (vertically opposite angles are equal)

c)  h=75°  (corresponding angles are equal)

    g=h  (vertically opposite angles are equal)

=12-225= -213

Answer:

-213

Step-by-step explanation:

=3|x+y|²-(xy)²

Subtitute value of x and y above:

=3(|3+-5|)²-(3×-5)²

=3(|-2|)²-(-15)²

=3(2)²-(225)

=3(4)-225

=12-225

=-213

Answer:

Your answer is x=7

Step-by-step explanation:

To get your answer, first you add 24+25. This equals 49.

Next, you see what you have to multiply by 7 to get 49.

7 goes into 49 7 times.

(7*7)-24=25.

==========================================================

Explanation:

Check out the diagram below.

U is between T and V, and U is on segment TV. We can see that the smaller pieces TU and UV add back up to the largest segment TV

TU + UV = TV

17 + 18 = TV

35 = TV

TV = 35

Segment TV is 35 units long.

Answer:

B. x = 50; m∠LOK = 114°

Step-by-step explanation:

Supplementary angles add to 180

∠MOK + ∠JOM=180

66+ ∠JOM=180

<JOM = <LOK since they are vertical angles

<LOK = x+64

66+ x+64=180

Combine like terms

130+x = 180

x = 180-130

x = 50

<LOK = x+64 = 50+64 = 114

Answer:

Yes, because if the multiplication identity is 1, the division identity may be -1 because it is the opposite.

Answer: 19 + × / 2

Step-by-step explanation:

Look for the key words:

Rise AND fall of the tide = Addition (19+x)

To show the AVERAGE = Division (Divide it by 2 because there is Monday and Tuesday)

The average difference between the tides for Monday and Tuesday Expression is 1/2×(19 + x)

Average difference Expression = 1/2 ×(19 + x)

Where:

19 represent the Difference between high and low tides on Monday

x represent  Difference between high and low tides on Tuesday

Inconclusion The Average difference Expression is  1/2 ×(19 + x)

Additional comment

The denominator on the left is x. The least common denominator on the right is 6. To clear fractions, you can multiply by the product of these values: 6x. Doing this gave us the one-step linear equation 6 = 3x.

As with any operation performed on an equation, the operation must be performed on both sides of the equation. Here, we multiply both sides by 6x. It is a bit unconventional and confusing to show that multiplication as you have shown it in your figure. Usually, it would be shown as in the 2nd line of the solution, above.

Answer:

(new-old)/old * 100%

130.7-124/124 = .054 = 5.4%

Step-by-step explanation:

Answer:

Step-by-step explanation:

A spring has a force formula of F = k*x

f = 125 N

x = 0.15 m

125 = k*0.15

k =833.33

F = ?

k = 833.33

x = 0.25 m

F = 833.33 * 0.25

F = 208.33 N

You could do this without solving for k

F1/F2 = x1/x2

F1 = 125 N

F2 = ?

x1 = 0.15

x2 =0.25

125 / F2 = 0.15 / 0.25               Cross multiply

125 * 0.25 = 0.15 * F2              Divide by 0.15

125*0.25 /0.15 = F2

F2 = 208.33 just as you got above
