Cross product property

Mathematics
1 answer:
Klio2033 [76]3 years ago
8 0

Using the cross product property on this proportion gives us the following equation:

20 (2x - 9) = 10 (9)

Use the distributive property and multiply

40x - 180 = 90

Add 180 to both sides

40x = 270

Divide 40 from both sides

x = 270/40

Simplify fraction

x = 27/4

This should be your answer. Let me know if you need any clarifications, thanks!

Alsion saves $29.26 each month. How many months will it take her to save enough money to buy a stereo for $339.12?
Darya [45]

Answer: 12 months (1 year)

We know that Alision gains $29.26 each month. She wants to buy a stereo for $339.12

You want to divide $339.12 with $29.26 to find the total months.

339.12 / 29.26 = 11.6

CHECK:

You want to round up, since she needs the money to buy a stereo. She's allowed to have more money.

29.26 * 12 = 351.12

It will take Alision 12 months (1 year) to buy her stereo.

To find the angle of rotation θ between the previous x and y axes and the new x′ and y′ axes, we use the formula: cotangent of 2
Tamiku [17]

The equation is the given one:

\cot 2\theta=\frac{A-C}{B}

Which is the same as:

\tan 2\theta=\frac{B}{A-C}

And the interval of the angle θ must be (0°,90°) so, 2θ must be (0°,180°).

So the statement is True.

Please I need help with this question: 2 + 2d > 6
Aleonysh [2.5K]

d > 2

Step-by-step explanation:

1) Subtract 2 from both sides.

2d > 6 - 2

2) Simplify 6 - 2 to 4.

2d > 4

3) Divide both sides by 2.

d >  \frac{4}{2}

4) Simplify 4/2 to 2.

d  > 2

Therefor, the answer is, d >2.
