The answer is 1/56 simplified

Step-by-step explanation:

Step-by-step explanation:

[tex] \frac{7}{8} - \frac{6}{7} = \frac{7 \times 7 - 6 \times 8}{7 \times 8} \\ \\ \frac{49 - 48}{56} = \frac{1}{56} [/tex]

Answer:

x ≈ 73.3

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos39° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{57}{x}[/tex] ( multiply both sides by x )

x × cos39° = 57 ( divide both sides by cos39° )

x = [tex]\frac{57}{cos39}[/tex] ≈ 73.3 ( to the nearest tenth )

Answer:

12

Step-by-step explanation:

6(5x−3)=

6 * 5 - 6 * 3 = 12

30 - 18 = 12

12 = 12

Hey there!

The distributive formula is:

a(b + c)

= a(b) + a(c)

= ab + ac

Now let’s solve for your given equation!

6(5x – 3)

= 6(5x) + 6(–3)

= 30x – 18

Answer: 30x – 18 ☑️

Good luck on your assignment and enjoy your day!

Step-by-step explanation:

Answer:

7 P.M.

Step-by-step explanation:

Time at which the walk was begun = 4 p.m.

Finished after rotating the clock 90° i.e. = 3 hours

Thus,

The time at which the task finished = 4 p.m. + 3hours

= 7:00 PM

Answer:

72°

Step-by-step explanation:

So the three angles of a triangle always add up to 180°. This means that

[tex]15x + 21x + 24x = 180[/tex]

This becomes:

[tex]60x = 180[/tex]

And solves as:

[tex]x = 3[/tex]

The largest angle has to be the one marked with 24x because it has the largest coefficient and x is a constant.

[tex]24x = 24(3) = 72[/tex]

The measure of the largest angle in the triangle is 72°.

72 degrees is the biggest angle in the given triangle.

The properties of the triangle are: The sum of all the angles of a triangle (of all types) is equal to 180°. The sum of the length of the two sides of a triangle is greater than the length of the third side. In the same way, the difference between the two sides of a triangle is less than the length of the third side.

Given that the three angles of the triangle are 24x, 21x, and 15x

Since the sum of all the angles of the triangle is always 180 degrees

Thus,

24x +21x + 15x = 180

60x = 180

x = 3

Thus, the biggest angle would be 24x

biggest angle of triangle = 24 * 3 = 72

Therefore, the biggest angle of the given triangle is 72 degrees

Answer:

Step-by-step explanation:

SOHCAHTOA

Sine is opposite over hypotenuse

Cosine is adjacent over hypotenuse

Tangent is opposite over adjacent

In this context, opposite means the side opposite of the angle. Adjacent means the side that is touching the angle. And the hypotenuse is the longest side, which is usually visually obvious.

3.) tan(25) = x/31

Use a calculator for tan(25), then multiply both sides by 31 to get your x value.

x = 14.5

4.) cos(48) = 17/x

Use a calc to do 17/cos(48) to get the x value

x = 25.4

5.) sin(theta) = 17/18

Divide 17/18, then take the inverse sine of both sides with a calculator to get the theta value

theta = 70.8 degrees

6.) tan(theta) = 31/42

Divide 31/42, then take the inverse tangent of both sides with a calc.

theta = 36.4 degrees

7.) Your best bet is to draw a picture. For my case, Im going to imagine it. The angle is 35 degrees and the hypotenuse is 300 feet. The question is asking for the opposite of the angle. This calls for sine.

sin(35) = x/300

x = 172.1 feet

Answer:

Step-by-step explanation:

It is easiest to just set both equations equal to each other and then solve for x.

Then we can plug the value we found for x back into either equation to find the corresponding y value.

This represents where on a graph the lines cross each other. At that intersection point, they would have the same x and y value.

[tex]-2x + 9 = 4x - 3[/tex]

Answer:

x=2 y=5

Step-by-step explanation:

Rewrite as -2x+9=4x-3. Solve for x: -2x-4x=-3-9--> -6x=-12--> x=2. Now that we know x=2, substitute x into each equation: y=-2(2)+9=-4+9=5. y=4(2)-3=8-3=5, thus making y=5
