B - Rhombus: A quadrilateral with four congruent sides; a rhombus is both a kite and a parallelogram
Answer:
-3/4
Step-by-step explanation:
change them to improper fractions
-5/2 - (-7/4)
now multiply -5/2 by two so the denominators are the same
-10/4 - (-7/4)
subtracting a negative number is the same as adding a positive number
-10/4 + 7/4
= -3/4
1) -5 + w/3 = -1
w/3 = -1 + 5
w = 4*3
w = 12
2) 24-3x = -27
-3x = -27 - 24
3x = 51
x = 51/3
x = 17
3) <span>-17 + n/5 = 33
n/5 = 33 + 17
n = 50 * 5
n = 250
4) A) </span><span>3m + 2 = -10
5) </span><span>25 = -75 - 5x
-5x = 25 + 75
x = 100 / -5
x = -20
6) D) </span><span>5 - 7x = 2
Hope this helps!</span>
Answer:
10/14, 15/21, and 20,28
Step-by-step explanation:
You just need to multiply a number on the numerator and the denominator. Remember, whatever you do to the numerator you have to do on your denominator.
Answer: B. 5/13
This is the same as writing
==========================================================
Reason:
We have two given sides of this right triangle. Use the pythagorean theorem to find the missing side.
a = 5 and b = 12 are the two known legs; c is the unknown hypotenuse
The hypotenuse is exactly 13 units long. This is a 5-12-13 right triangle.
Now we can compute sine of theta
This points us to choice B as the final answer.
----------------
Extra Info (optional)
- 5/12 is the value of tan(theta) since it's opposite/adjacent
- 12/5 is the value of cot(theta), the reciprocal of tangent
- 12/13 is the value of cos(theta), because cos = adjacent/hypotenuse
